Our 1 ½ composite floor deck is the narrowest of our composite steel deck products. Each of our steel floor decking is used as a platform before and during concrete placement, removing the need for pricey wood forms. Concrete is poured on top of the 1 1/2” metal floor decking and creates a strong bond between concrete and deck. We recommend pouring 2” of concrete over the ribs of the deck for a total slab thickness of 3.5”. Discover more about our 1 ½” composite floor deck systems.

In order to understand which composite steel deck you’ll need for the job, it’s important to know the following information:

  • The depth of the slab 
  •  Clear distance between supports.

This information is vital for determining which variety of composite floor decking you’ll need. 

D-MAC’s metal floor decking is manufactured by members of the Steel Deck Institute and meets all of the necessary steel deck certifications.

What is Composite Steel Deck Made Of?

D-MAC’s composite steel deck has embossments in the vertical ribs, allowing it to form a tight bond with the concrete slab and develop a composite floor system. Once the concrete is poured over the metal decking and the concrete cures, the completed composite steel floor decking system will provide superior strength and durability for years to come.

Oftentimes, people think that the composite in composite steel deck means that it’s a combination of steel and other materials, like composite lumber. But really, “composite” refers to the finished metal floor decking system, which is now a composite of concrete and steel decking created by pouring concrete over metal decking that has special embossments that allow the steel deck to act like rebar.

How Should I Store Composite Steel Deck?

When your composite steel deck needs to be stored on-site prior to installation, it’s important to protect it from corrosion, deformation, and any other types of damage. When your metal floor decking is not being actively installed, it should be stored off the ground, with one end elevated to provide drainage. To provide further protection from corrosion, we recommend that composite steel floor deck bundles are protected against condensation with a ventilated waterproof covering. It’s notably important to properly store your metal floor decking if you are in a climate with snow, ice, and salt, as these conditions can quickly cause corrosion. If you have any questions regarding storing your composite steel deck, the experts at D-MAC Industries are always happy to assist.
