Parking garages are an integral part of our nation’s infrastructure. Although they are subject to more deterioration than other building types, their maintenance is typically not considered of primary importance to building owners or managers.
Stainless steel is often used as a railing material, especially where corrosion resistance is a major concern. However, many design/construction professionals may be unaware of the finer nuances of selecting the right type of material. Having a better understanding of finishes is critical.
Specifying high-performance coatings for structural steel framing, decking, or curtain walls can be a tall order when the application surface is located hundreds of feet above ground level. The specified coatings must protect the structural integrity of these hard-to-reach steel exposures against corrosion.
Galvanizing is one of the best ways to protect steel, but the complex series of reactions necessary to prevent corrosion can be undermined by exposure. When hot-dipped galvanized steel is first exposed to the atmosphere, near-pure zinc at the surface reacts with oxygen to form zinc oxide.
