16 Gauge Metal Decking Applications – Heavy Duty Structural Uses, Load Capacity & Specs

16 Gauge Metal Decking Applications

16 gauge metal decking is one of the heaviest and strongest standard decking options used in construction. Designed for extreme load conditions, long spans, and high-impact environments, it is commonly specified in heavy industrial, infrastructure, and structural applications where maximum strength and durability are required.

With a significantly thicker profile than 18, 20, and 22 gauge decking, 16 gauge decking delivers superior load capacity, minimal deflection, and long-term structural reliability.
