types of metal Roof deck
A roof deck, as defined by the Steel Deck Institute (SDI), is a structural steel component that enhances roof strength, load distribution, and stability. Available in Type A, B, and N profiles, it supports insulation, waterproofing, and drainage systems. Designed for commercial, industrial, and institutional buildings, it meets ANSI/SDI RD-2017 standards, ensuring durability and compliance.

-
What gauge is most commonly used for Type B decking?20 gauge is generally the most common for Type B decking due to its balance of cost and strength for typical applications. However, project-specific requirements can necessitate other gauges.
-
What is the difference between G60 and G90 galvanized finishes?The difference between G60 and G90 galvanized steel is the amount of zinc coating applied for corrosion protection. G60 has a coating of 0.60 oz/ft² (183 g/m²), while G90 has 0.90 oz/ft² (275 g/m²), providing 50% more zinc and greater resistance to corrosion G60 is suitable for indoor applications or low-moisture environments, such as HVAC, interior metal structures, and construction panels. In contrast, G90 offers superior protection and is ideal for outdoor use, roofing, steel decking, and structures exposed to weather, humidity, or corrosive conditions. If the application requires higher durability and corrosion resistance, G90 is the best choice. However, if moisture exposure is minimal and cost efficiency is a priority, G60 may be sufficient.
-
What are the maximum spans for the 1.5" Type B deck?Maximum spans depend on the gauge, span type, and load requirements. For example, 22-gauge decks can span up to 8 feet under multiple spans, while 16-gauge decks can span up to 14 feet. Always consult load tables for precise details.
-
Can 1.5" Type B metal decking be customized for specific projects?Yes, the deck can be customized in terms of gauge, finish, and length. Custom lengths are cut to suit project needs, reducing waste and optimizing installation efficiency.
-
Does 1.5" Type B metal decking meet industry standards?Absolutely. It complies with Steel Deck Institute (SDI) standards and American Iron and Steel Institute (AISI) design guidelines, ensuring quality, safety, and compatibility with construction codes.
