Steel decking sheets for composite floors

Composite metal deck acts as permanent formwork and tensile reinforcement for concrete slabs on steel beams. It speeds up construction by removing temporary propping and formwork in many spans.

Overview

We take enquiries for galvanized deck profiles, cut to length to your layout drawings, with accessories such as edge trims and shear connectors.

Available forms

  • Re-entrant composite deck
  • Trapezoidal composite deck
  • Roof deck
  • Edge trims, closures and shear studs

Selection guidance

How to specify steel decking (metal deck)

01

Unpropped span drives thickness

Construction-stage span without props determines the deck gauge. Use the manufacturer's tables or the engineer's design.

02

Coordinate shear studs

Through-deck stud welding needs suitable galvanizing thickness and qualified welders.

03

Fire rating

Fire resistance depends on slab depth, reinforcement and protection. Check the design meets Civil Defense requirements.

Steel Decking (Metal Deck): FAQs

What is composite decking?
A profiled steel sheet that bonds with the concrete slab so the deck and concrete act together, the deck serving as formwork and bottom reinforcement.
Is metal deck the same as roof deck?
No. Floor decks are designed for composite action with concrete; roof decks support roofing systems and insulation without a structural slab.
Do you need props with steel decking?
Not always. Within the profile's unpropped span limit no props are needed; beyond it, temporary propping is required during the pour.
