Steel is 100 percent recyclable. Each year, nearly 68.7 percent of all steel scrap is North America is recycled. Steel does not contribute to the growth of landfills. Steel framed structures stay straight and true and do not expand and contract with humidity and temperature changes. This means that door and windows openings framed with steel remain stable and this saves on energy costs. Cold-for...

Influence of design on corrosionThe design and detailing of a structure can affect the durability of any protective coating applied to it. Structures designed with many small structural components and fasteners are more difficult to protect than those with large flat surfaces. The key issues to consider include:Access for coating application and maintenanceAvoidance of moisture and debris trapsAvo...

The corrosion of structural steel is an electrochemical process that requires the simultaneous presence of moisture and oxygen. In the absence of either, corrosion does not occur. Essentially, the iron in the steel is oxidised to produce rust, which occupies approximately 6 times the volume of the original material consumed in the process. The general corrosion process is illustrated here.Atmosphe...
