What Is a Decking Sheet?

A decking sheet is a profiled steel sheet specially engineered to provide excellent structural support for roofs, floors and mezzanine systems. Unlike conventional flat sheets, a decking sheet features deep ribs or embossed profiles that significantly increase its load-bearing capacity without adding excessive weight. Available in various designs such as metal decking sheets, steel deck sheet, deck profile sheet, corrugated deck sheet, roller deck sheet and TR 60 deck sheet, these sheets are selected based on project-specific structural and architectural requirements. They are widely used because they improve construction speed while reducing the overall steel and concrete requirement.

Construction of Decking Sheet PUF Panels

A Decking Sheet PUF Panel consists of three primary layers that work together to deliver strength, insulation and durability. The outer layer is a high-quality steel deck sheet or profiled metal sheet that provides exceptional structural support and protects the panel against external weather conditions.
