1.5" Type B Roof Deck questions
What gauge do most buyers choose for Type B decking?
20 gauge is typically the most common, because it offers a good balance of cost and strength for ordinary applications. Some projects need a different gauge based on their requirements.
What separates G60 from G90 galvanized finishes?
The coating on G60 is 0.60 oz/ft² versus 0.90 oz/ft² on G90. That makes G90 50% heavier in zinc and more corrosion resistant. G60 works for indoor applications or low-moisture environments, while G90 is better for outdoor use, roofing, steel decking, and structures facing weather, humidity, or corrosive conditions.
What are the maximum spans of the 1.5" Type B deck?
The answer depends on gauge, span type, and loading. For instance, 22-gauge deck spans up to 8 feet in multiple spans, and 16-gauge deck spans up to 14 feet. For exact numbers, refer to the load tables.
Can I get 1.5" Type B metal decking customized for my Lakeland project?
Yes, gauge, finish, and length are all customizable. Lengths are cut to project needs, so there is less waste and installation goes more efficiently.
