What is the most common type of composite metal decking

The composite metal decking was the positive moment support in the reinforced concrete slab by interlocking the metal sheet and the concrete slab. Additionally, the deck even acted as the concrete formwork. The resulting combined component was now recognized as composite metal floor deck.

Composite floor decking is using the steel beams to be connected with the concrete floor slabs. It utilizes the advantage of both steel and concrete. Therefore, it is more cost-effective form of construction.

This is the most common type of composite metal decking. Composite metal decking can be divided into trapezoidal metal deck ,re-entrant metal deck and flat profile.

The trapezoidal metal deck

The trapezoidal metal deck is very popular in the world and widely used; flat profile occupies more than 60% of the Chinese metal deck market. In Solideck, SD51-915, SD76-915, .The trapezoidal metal deckThe trapezoidal metal deck can be used as Composite floor decking because it needs to have indentation itself, can work with concrete, and can bear the later load when it is stressed.

The re-entrant metal deck

The re-entrant metal deck is widely used overseas. Solideck has the following two board types: SD53-600, SD51-760. The re-entrant metal deck is used in Bangladesh, Macau and other projects. The re-entrant metal deck can not only be used as Composite floor decking, but also can provide suspension parts due to its own plate characteristics, which is really a blessing for electromechanical installation

The flat profile

While SD65-510, SD65-555, SD65-720, SD46-600 are all flat profile. The flat profile is a unique deck type in China, which absorbs the advantages of re-entrant metal deck and improves its shortcomings. The flat profile not only has a smooth bottom surface, but also can bear larger spans and loads, and the bottom can still be hung.

The above are the deck types that Solideck can provide as Composite floor decking, you can choose according to the project status.
