What Is Galvanized Steel Deck?

Galvanized steel decking is suitable for steel structure construction to improve its stiffness. Galvanized b decking is made of high-zinc galvanized sheets and profiled through rolling and cold bending, which offer excellent corrosion resistance and great durability. Corrugated metal deck is used for supporting floor concrete, including structural roof deck or composite floor deck.

Galvanized Roof Deck

Galvanized corrugated metal decking is used as a strong base in roof construction. The most popular one is the Type B-galvanized roof decking with wide ribs. Other common types include A deck (narrow ribbed roofing panel), F deck (intermediate rib), and N deck (deep rib).

Galvanized Floor Deck

A galvanized floor decking is a kind of corrugated metal panel for floor application. It is also called composite deck because it is a combination of concrete and metal roof panels. The floor deck serves as the tensile reinforcement to improve the rigidity of the floor panel and reduce the usage of reinforcement and concrete.

The main difference between the roof deck and floor deck is in embossment patterns. The former uses a smooth panel, with no embossment pattern. While the latter has special embossment patterns to create mechanical and chemical bonds between the deck and the concrete.

Requirements of Composite Floor Deck

(1) The material for the composite deck is corrugated galvanized sheets with high zinc layer so that the service life of the floor deck can be more than 20 years.

(2) The average groove width for pouring concrete shall not be less than 50mm. When there are connectors in the groove, the composite deck should not be greater than 80mm in height

(3) The thickness of the composite deck should not be less than 90mm. Also, the thickness of the concrete above the corrugated steel roof decking surface should not be less than 50mm

(4) The end of the composite galvanized metal decking should be fixed with bolt anchors. The stud should be set at the concave rib of the corrugated sheet, penetrating the steel sheet, and then be welded firmly to the steel beam

(5) The supporting length of the corrugated metal sheet on the beam should not be less than 50mm and not less than 75mm on masonry.
