Used for decking and outdoor flooring.MPI’s 2” Composite Decking is a durable, high-performance metal floor deck designed to serve as a permanent form for poured concrete slabs. Its 2-inch deep corrugated profile includes side embossments that bond with the concrete, creating a strong composite floor system that enhances structural support and bending resistance. With a 36-inch coverage width, this decking supports spans from 1 foot to 10 feet, depending on gauge and back-span conditions (single, double, or triple). Available in 20, 18, and 16 gauge galvanized steel, MPI Composite Decking can also be supplied in primer-painted or G50 galvanized finishes—making it ideal for a wide range of outdoor flooring and structural applications.
