​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.
