What is 1 ½” Composite Deck Used For?

This flooring system has a dual purpose and acts as a platform before and during concrete placement, eliminating pricy wood forms, and used as positive reinforcement for the concrete slabs, eliminating the need for rebar in most cases. Sometimes referred to as metal deck, this product is typically used for multiple floors in commercial buildings, bridges, porches, parking garages, storage facilities, and more.

1 ½” Composite Floor Deck is designed to be used as a floor deck where concrete is poured on top of the deck. This deck has indentations and embossments, which allow for better bonding between concrete and deck. These embossments will grip the concrete slab and reinforce it for a strong bond and are designed to interlock.

Composite floor deck provides positive reinforcement while eliminating the time and cost of wood forming, making it incredibly durable and efficient. Furthermore, unlike conventional slabs, the combination of composite and concrete creates a stronger and lighter application. The composite steel deck slab is used to act as a support structure for the concrete’s entire life.
