What Is Composite Metal Decking

Composite steel deck is a permanent concrete form and provides positive reinforcement while it eliminates the time and cost of wood forming.

What is composite metal decking.

Composite slabs comprise reinforced concrete cast on top of profiled steel decking which acts as formwork during construction and external reinforcement at the final stage. Composite deck gains its strength from the bond between concrete and steel for a high performance composite floor deck system. Composite metal floor decking is metal floor deck with an embossment pattern manufactured into the sides flutes at regular intervals. Steel deck panels are supplied with both galvanized and painted finishes to meet an array of project finish requirements.

A composite steel deck combines the tensile strength of steel with the compressive strength of concrete to improve design efficiency and reduce the material necessary to cover a given area. In this case we are referring to the metal deck and the concrete slab. Additionally composite steel decks supported by composite steel joists can span greater distances between supporting elements and have reduced live load deflection in comparison to previous construction methods. Our lightweight composite and non composite steel deck profiles have depths that range from 7 8 to 71 2.

Panel lengths range from 3 6 to 45. Composite is the combination of 2 or more distinct substances to create a solid material. Composite floor deck systems are strong and versatile load tables. Composite metal deck composite deck was designed with a ribbed profile or bump outs in the flutes called embossments these embossments grip the concrete as it cures creating a reinforced concrete slab that serves as a permanent form with positive reinforcement.

The dimensionally stable steel of trex elevations stays in place giving you consistently stronger straighter safer and smarter decking than what wood can offer. The composite action allows the deck to serve as the tensile reinforcement for positive bending in the slab which significantly reduces or eliminates the need for rebar in the slab and lowers material and labor costs. Wood substructures split warp and shift leading to an uneven surface in the deck boards above. They each have different physical characteristics and when they combine they create a composite system.

The embossments allow the concrete to bond with the metal decking panel as the concrete cures. Asc steel deck offers a robust selection of products. Trapezoidal decking may be over 200 mm deep in which case it is known as deep decking. Formlok in order to create an effective composite slab the metal floor deck is manufactured with an embossment pattern.
