Structural Steel Decking 

Structural steel decking is a cold-formed, corrugated metal sheet used as a structural element in constructing floors and roofs. It serves as a working platform during construction and acts as permanent formwork for concrete slabs. Steel decking provides lateral bracing to the building's frame and contributes to its overall structural integrity. It comes in various profiles and gauges to suit different loading requirements and applications. As a structural steel decking supplier, Triple-S Steel® is your partner for all steel decking applications.
