Water leaks bring small amounts of salts and acids from the roof surface and, in some cases, from the insulation surfaces it has passed through or through them. While a steel deck is sure to be the most durable type of outdoor deck, in order for it to last as long as possible, you need to maintain it properly. Steel platforms have been increasingly used in a variety of construction applications due to their many advantages over competing materials. However, given its durability, the steel platform is susceptible to rust.
Nothing is more harmful to your steel deck than rust, which is why proper maintenance is so important. Usually, the galvanized metal platform is preferred because there is no need to apply the finished paint layer to the metal platform. This type of metal platform is also suggested in corrosive or high humidity environments. You can also protect your steel deck with regular use of specially formulated metallic paint mixed with primer.
Reapplying this mixture as needed will help protect older covers that are more susceptible to rust. For the paint to work effectively, remember to fix small dents and holes in the steel before application. However, if you know that there is a steel platform under the insulation and you notice leaks or pond problems, there is a good chance that your steel deck has been affected. The metal platform can simply be used as a form of staying in place for pouring concrete, in which case the concrete platform is the structural component and the metal does not serve any structural purpose after the concrete has cured.
The premium painted gray metal deck is generally found in applications where the metal deck does not have to be exposed. The phosphated and painted metal deck has a top deck that is neither galvanized nor painted, combined with a primed and painted finish on the bottom. Often undetected by landlords, managers and tenants, roof corrosion and mechanical fasteners weakens the roof deck to the point where, in some cases, it can present safety concerns for roofing crews and workers. The steel elements of your platform are in the insulation, so most often corrosion problems are encountered on the platform when dealing with leakage problems.
