Gauge
Gauge | Thickness (inches) | Weight (lbs/sq ft) | Typical Applications |
|---|---|---|---|
22 | 0.0295 | 1.6 | Light-duty roofing and small spans. |
20 | 0.0358 | 2 | Medium spans, roofing, and siding. |
18 | 0.0474 | 2.6 | Heavy-duty applications |
16 | 0.0598 | 3 | Heavy load spans |
The Type B deck is available in a range of gauges, including 22, 20, 18, and 16. These gauges offer varying thicknesses and load capacities to suit specific project needs. Thinner gauges (22 and 20) are lightweight and cost-effective, ideal for shorter spans and lighter loads. Thicker gauges (18 and 16) provide enhanced structural strength and can support longer spans and heavier loads, making them perfect for demanding applications.
Finish
Finish Type | Details |
|---|---|
Galvanized G60 | Zinc coating of 0.6 oz/ft². Recommended for general environments. |
Galvanized G90 | Zinc coating of 0.9 oz/ft². Ideal for highly corrosive environments. |
Prime-Painted | Provides a base coat for additional protection or paint adhesion. |
Bare Steel | Unfinished; typically for indoor use or controlled environments. |
To ensure durability and long-term performance, the Type B deck comes in multiple finish options, including galvanized (G60 and G90) and prime-painted. Galvanized finishes provide excellent corrosion resistance, with G90 offering higher zinc coating for environments with greater exposure to moisture or chemicals. The prime-painted option adds a protective base coat, making it suitable for projects requiring additional layers of paint or coatings. These finishes extend the deck’s lifespan and protect it from environmental wear and tear.

-
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.
