In many projects, increasing the cross-section of the components raises the weight and cost, but doesn&#039;t solve the underlying causes that accelerate deterioration.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Corrosion, water accumulation, inadequate coatings, manufacturing defects, and lack of maintenance tend to have the greatest impact. Therefore, we need to analyze the entire structure, from the choice of material to the actual conditions of use.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">With an environmentally friendly design and a well-specified protection system, we can preserve the steel without unnecessarily increasing its thickness.<\/span><\/p>\n<h2><b>Are steel thickness and durability the same thing?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">The thickness of the steel influences the strength and rigidity of the structure. However, it does not, by itself, represent a solution against corrosion.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">When a part is continuously exposed to moisture, salts, or chemical agents, the corrosive process begins on the surface. Wear progresses gradually and can lead to loss of cross-section over time.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">A thicker component allows for a greater amount of material to be lost before this loss becomes critical. Even so, corrosion will continue to occur if the cause is not controlled.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Therefore, increasing the thickness may only postpone the problem. Furthermore, this choice adds weight to the structure and may require changes to foundations, connections, transport, and assembly.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Structural design must comply with the loads, spans, and conditions specified in the project. Corrosion protection, on the other hand, must be appropriate for the exposure environment.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Therefore, we need to separate two concepts. A <\/span><b>structural capacity<\/b><span style=\"font-weight: 400;\"> It is related to the behavior of the part under stress. Durability depends on the ability to maintain this performance over the expected period.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">A structure can have correctly sized components and still exhibit premature wear. This occurs when the design does not consider accumulated water, sea air, pollution, or maintenance.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">There is also the opposite risk. Increasing the thickness unnecessarily can increase steel consumption without proportionally extending the lifespan.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Before modifying a section, we need to identify the deterioration mechanism. In many cases, drainage, coating, and inspection offer more efficient results.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Our content about<\/span><a href=\"https:\/\/www.grupoacocearense.com.br\/en\/resistencia-do-aco-o-que-voce-precisa-saber-sobre-isso\/\"> <span style=\"font-weight: 400;\">steel strength and its characteristics<\/span><\/a><span style=\"font-weight: 400;\"> It helps to differentiate mechanical properties and application criteria.<\/span><\/p>\n<h2><b>What determines the lifespan of metal structures?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">The service life corresponds to the period during which the structure maintains safety and performance compatible with its intended use. To achieve this result, several factors need to work together.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The first is the quality of the steel. The material must meet the class, dimensions, and properties defined by the project.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The second factor is the environment. A warehouse located in a dry region faces different conditions than a structure near the sea or a chemical plant.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">We also need to consider the design of the components. Areas that accumulate water, debris, or moisture tend to suffer more intense corrosion.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Manufacturing interferes in a similar way. Cuts, welds, punctures, and contamination can damage coatings or create vulnerable areas.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The main factors that affect durability include:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Material quality and specifications:<\/b><span style=\"font-weight: 400;\"> The steel must have a composition, strength, and dimensions compatible with the project.

However, the intensity of the process varies depending on ventilation, temperature, and the presence of contaminants.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Sea spray represents a more aggressive condition. Salts carried by the wind reach the surface and can concentrate in cracks, joints, and areas protected from rain.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Industrial areas also require attention. Vapors, particles, and chemicals can attack the steel or the applied coating.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Even indoor environments can present risks. Warehouses with condensation, industrial laundries, and food processing areas maintain damp surfaces for extended periods.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Therefore, broad classifications, such as &quot;indoor&quot; or &quot;outdoor,&quot; are not always sufficient. We need to consider the microenvironment where each piece will be installed.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">A pillar protected by a covering can accumulate dirt and salts without receiving natural washing. A piece directly exposed to rain, on the other hand, can dry more quickly.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Geometry also affects water exposure. Horizontal surfaces retain more water than inclined pieces. Pipes without drainage can accumulate liquid internally.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Furthermore, areas close to the ground often receive moisture, mud, and cleaning products. Pillar and support bases require specific detailing.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In existing structures, signs of corrosion in nearby elements help to understand the environment. This observation can support the choice of protection system.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">However, the analysis should consider potential differences in materials, age, and maintenance conditions.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">THE<\/span><a href=\"https:\/\/www.icz.org.br\/site\/pdf\/ICZ-MANUAL-DE-ESPECIFICACAO-DE-GALVANIZACAO-POR-IMERSAO-A-QUENTE-2021.pdf\"> <span style=\"font-weight: 400;\">ICZ galvanizing specification manual<\/span><\/a><span style=\"font-weight: 400;\"> The durability of the coating is related to the exposure conditions and the thickness of the zinc layer.<\/span><\/p>\n<h2><b>What is the role of coatings in protecting steel?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Coatings create a separation between the steel and the environment. Some also offer additional protective mechanisms.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The paint acts primarily as a barrier. When the system remains intact, it reduces the entry of water, oxygen, and contaminants.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">However, scratches, adhesion failures, and wear can expose the metal. Therefore, surface preparation and proper application are of great importance.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Galvanization uses a layer of zinc. In addition to providing a barrier, zinc can offer... <\/span><b>sacrificial protection<\/b><span style=\"font-weight: 400;\"> in small areas where the steel was exposed.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This behavior occurs because zinc tends to oxidize before iron. In this way, it helps protect the steel near the damage.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Hot-dip galvanizing forms layers bonded to the surface of the material. It is used in structures, railings, supports, profiles, and various components.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Galvanized sheets in continuous lines can be transformed into roofing sheets, light profiles, and metal cladding.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Our article about<\/span><a href=\"https:\/\/www.grupoacocearense.com.br\/en\/processo-de-galvanizacao-entenda-como-funciona\/\"> <span style=\"font-weight: 400;\">the galvanizing process<\/span><\/a><span style=\"font-weight: 400;\"> It explains the main steps of this treatment.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Another way is the <\/span><b>duplex system<\/b><span style=\"font-weight: 400;\">, This system combines galvanizing and painting. In this system, the zinc layer protects the steel, while the paint reduces the exposure of the metallic coating.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This combination can be considered when the environment is harsh or when the project requires a specific appearance. However, the paint must be compatible with the galvanized surface.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">There are also sheets coated with metal alloys that combine zinc and other elements. These solutions can offer different performance depending on the environment and application.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The choice should be based on technical specifications, tests, and manufacturer recommendations. Generic commercial terms do not replace information about the composition and quantity of the coating.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Furthermore, the coating needs to adapt to the manufacturing process. Folds, cuts, and welds can create conditions that differ from the original surface.<\/span><\/p>\n<h2><b>How can the design increase lifespan without adding weight?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">A design focused on durability avoids conditions that accelerate corrosion. This strategy usually yields better results than increasing the mass of the parts.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The first step is to ensure proper drainage. Rainwater, wash water, or condensation should not be allowed to accumulate.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Profiles and plates need to be positioned to allow for drainage. In closed parts, drainage holes may be necessary.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The second precaution involves ventilation. Stuffy areas dry slowly and keep the surface moist for longer.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Narrow crevices also deserve attention. They retain water, salts, and debris, creating conditions favorable to localized corrosion.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Overlapping connections can form this type of region. Therefore, we need to evaluate sealing, continuous welding, or spacing between the components.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Contact between dissimilar metals must be controlled. In the presence of moisture, certain combinations can cause galvanic corrosion.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In these cases, insulating materials and compatible fastening systems help to separate the metals.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Accessibility is another important point. The design must allow for inspection, cleaning, and repair of surfaces.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Completely sealed elements can hide corrosion until the loss of cross-section becomes significant. Therefore, inspection openings may be necessary.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The detailing also needs to protect the bases of the pillars. Water and dirt tend to accumulate near the floor.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Solutions that raise the structure, facilitate drainage, and protect the junction with the foundation help reduce exposure.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">On roofs, gutters and flashing need to channel water without directing it towards the structures. Recurring leaks can deteriorate purlins, connections, and supports.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Like this, <\/span><b>draw to dry<\/b><span style=\"font-weight: 400;\"> It is one of the most effective measures to extend the lifespan of metal structures.<\/span><\/p>\n<h2><b>How can we increase durability without raising structural costs?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">The first step is to specify the steel according to the actual loads. Then, we must define the surface protection according to the environment.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This separation avoids the use of heavier parts simply to create a buffer against corrosion.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">A properly dimensioned structure can be galvanized, painted, or treated with a combination of both. The decision depends on the level of exposure and the planned maintenance.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Another measure involves distributing the investment according to criticality. Not all parts face the same conditions.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Items directly exposed to rain may require superior protection. Interior, dry items, on the other hand, can utilize a simpler system.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This approach reduces costs without compromising durability. However, mapping needs to be done during the design phase.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The use of standardized components also helps. Commercially available profiles, sheets, and tubes tend to make purchasing, replacement, and manufacturing easier.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Furthermore, an efficient cutting plan reduces waste. Excess leftovers increase costs without improving performance.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Coordination between engineering, manufacturing, and assembly avoids on-site adaptations. Holes and cuts made after the coating has been applied require repairs.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Therefore, the more operations that are planned before final protection, the smaller the number of vulnerable areas tends to be.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">We also need to compare the life cycle cost. An alternative with a lower initial investment may require frequent repainting.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In tall structures, maintenance access can represent a significant portion of the cost. Platforms, area isolation, and operational interruptions need to be factored into the calculation.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In these cases, investing in a more durable protection system can be advantageous, even without increasing the thickness of the parts.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Our content about<\/span><a href=\"https:\/\/www.grupoacocearense.com.br\/en\/apoio-tecnico-na-escolha-de-materiais-como-evitar-desperdicios-e-retrabalhos-na-obra\/\"> <span style=\"font-weight: 400;\">technical support in the selection of materials<\/span><\/a><span style=\"font-weight: 400;\"> This demonstrates how more precise specifications help reduce losses and rework.<\/span><\/p>\n<h2><b>How do cuts and welds affect surface protection?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Cuts and welds alter the continuity of the coating. Therefore, these operations need to be part of the manufacturing planning.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In coated sheets, the cut exposes the edge of the steel. Depending on the system, the surrounding protection can reduce corrosion in small areas.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">However, extensive edges and damaged areas require treatment. The procedure should follow the material specifications.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Welding generates heat and can remove coatings near the joint. Additionally, spatter and residue affect surface quality.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">After welding, the area must be cleaned and treated with the chosen repair system. Zinc-rich paints and metallization are among the possible solutions for certain projects.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The choice depends on the extent of the damage and the conditions of exposure. Applying any product without preparation does not guarantee recovery.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">We also need to observe the geometry of the welds. Irregular welds and porous areas retain moisture and make painting difficult.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The manufacturing process must utilize clean tools. Particles of other metals can contaminate the surface and create corrosion points.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For parts intended for hot-dip galvanizing, the design must include ventilation and drainage. Closed cavities hinder the process and can pose risks.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The technical guide of<\/span><a href=\"https:\/\/galvanizeit.org\/uploads\/publications\/Design-Guide-AGA-2023-reduced-size_2024-09-10-171216_zgwg.pdf\"> <span style=\"font-weight: 400;\">American Galvanizers Association<\/span><\/a><span style=\"font-weight: 400;\"> It provides recommendations for designing parts that will be galvanized after manufacturing.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Therefore, the coating should not be treated as an isolated step. It needs to be compatible with the geometry and the manufacturing method.<\/span><\/p>\n<h2><b>How do transportation, storage, and assembly interfere?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">The structure may leave the factory with adequate protection and still suffer damage before installation. Transportation and storage must preserve the applied system.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">During movement, chains, cables, and supports can scratch the surface. Intermediate guards help reduce direct contact.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The pieces should not be dragged over each other. This movement causes abrasion and can remove part of the coating.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">During storage, the material must be kept off the ground. Furthermore, the storage conditions should prevent water accumulation and deformation.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Galvanized parts stored wet and without ventilation can develop whitish stains. This condition occurs when the surface is unable to dry properly.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Paints also require care. Stacking them before they are fully cured can score or remove the coating.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The identification of the parts must remain visible. Swaps during assembly may cause a component to be placed in a different position than intended.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">On the construction site, improvised drilling and cutting should be avoided. When authorized, the team must replace the protective barrier.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Lifting should utilize points compatible with the weight and geometry. Deformations can create retention areas or compromise the fit.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Our article about<\/span><a href=\"https:\/\/www.grupoacocearense.com.br\/en\/conheca-as-melhores-praticas-de-armazenamento-de-aco\/\"> <span style=\"font-weight: 400;\">proper storage of steel<\/span><\/a><span style=\"font-weight: 400;\"> It provides guidelines for preserving the products before use.<\/span><\/p>\n<h2><b>How does maintenance extend the lifespan of a structure?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Even the most durable protection systems need inspection. Maintenance identifies faults before corrosion progresses.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Frequency should be adjusted to the harshness of the environment and the importance of the structure. Coastal, industrial, or very humid areas may require more frequent checks.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Visual inspection should look for stains, blisters, peeling, rust, and buildup of debris. Edges and joints deserve special attention.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Pillar bases, areas under gutters, and areas protected from rain also need to be checked. These points can retain moisture for longer.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In addition, we need to check drainage and ventilation. Holes blocked by dirt cease to function.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Minor damage to the coating should be repaired before it spreads. Surface preparation needs to remove corrosion, contaminants, and loose particles.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Repairs should be performed using products compatible with the original system. Inappropriate mixtures may result in poor adhesion or interlayer reactions.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Regular cleaning helps remove salts and pollutants. However, harsh products can damage the coating.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Therefore, the maintenance plan should document methods, materials, and frequency. Photographs and measurements help track progress.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In critical structures, coating thickness tests and section loss assessments can complement visual inspection.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The content about<\/span><a href=\"https:\/\/www.grupoacocearense.com.br\/en\/manutencao-preditiva-na-industria-como-antecipar-falhas-e-otimizar-a-producao\/\"> <span style=\"font-weight: 400;\">Predictive maintenance in industry<\/span><\/a><span style=\"font-weight: 400;\"> It shows how data and inspections support decisions before failures occur.<\/span><\/p>\n<h2><b>How do you calculate the life cycle cost?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Life cycle cost considers purchase, manufacturing, installation, maintenance, and replacement. This perspective helps to compare solutions more accurately.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Increasing the thickness raises the weight of the steel from the start. Consequently, transport, lifting, and foundations can also be impacted.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">On the other hand, a good coating adds protection primarily to the surface. This solution can extend durability without significant changes in dimensions.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The cost of future interventions needs to be estimated. A low, accessible structure requires simpler maintenance than an operational industrial roof.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Production stoppages are also factored into the calculation. Painting a structure inside a factory may require isolation and interruption of activities.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Furthermore, we need to assess the frequency of interventions. An inexpensive system that requires frequent repairs can lead to higher accumulated costs.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The analysis should use the same period for all alternatives. Comparing only the initial value favors solutions that may not maintain performance.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">We also need to consider the possibility of expansion. Standardized and documented systems facilitate replacements and new phases of the project.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Supplier quality influences this outcome. Identified materials that meet specifications reduce risks during execution.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Therefore, the best solution is not necessarily the heaviest or the cheapest.

In more demanding projects, certificates and inspection reports help to confirm compliance.<\/span><\/p>\n<h3><b>Can a duplex system be repaired locally?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Yes, depending on the extent of the damage. The area needs to be cleaned and prepared before applying the recommended system. The repair must be compatible with the existing zinc and paint.<\/span><\/p>\n<h3><b>Do white spots mean that the galvanized part has lost its protection?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Not always. Moisture stains can appear when wet items are left without ventilation. However, the area should be assessed to determine the extent of the damage.<\/span><\/p>\n<h3><b>Do internal structures also need protection against corrosion?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Yes, when they are exposed to condensation, washing, vapors, or chemicals. The absence of rain does not mean that the environment remains dry.<\/span><\/p>\n<h3><b>How do you know when your coating needs maintenance?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Blisters, peeling, rust, loss of adhesion, and exposed steel indicate a need for evaluation. Periodic inspections help identify the problem before it progresses.<\/span><\/p>\n<h3><b>Can the coating alter the dimensions of the connections?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Yes. The added layer can interfere with holes, threads, and fittings. Therefore, tolerances and connection details need to be considered in the protection process.<\/span><\/p>","protected":false},"excerpt":{"rendered":"<p>The lifespan of metal structures does not depend solely on the thickness of the steel.
