Production
Roll-formed from galvanized or Al-Zn coated coils; profiles feature ribs with embossments for shear bond. Sheets are cut-to-length and bundled per pour sequence; closures, end caps, and fasteners are supplied to suit.
Quality
Materials and coatings for durability and composite action:
- Base Steel: S220GD – S350GD (formability & strength)
- Metal Coating: Z275 galvanized or AZ150 Al-Zn (typical)
- Design Use: Non-composite (formwork) or composite slabs per engineer’s design
Production Range
Profile Heights (typ.)50, 60, 75 mm (others on request)
Typical Thickness0.70 – 1.20 mm
Effective Cover Width≈ 900 – 1000 mm (profile-dependent)
Concrete GradesC25/30 – C35/45 (per project spec)
AccessoriesEnd closures, edge trims, hangers, shear connectors, fixings
Applications
- Composite Floors: Office/industrial slabs with integrated deck reinforcement
- Mezzanines & Platforms: Fast-install spans with minimal propping
- Parking Structures: Durable slabs with repeatable pour cycles
- Refurbishment: Over-decking on existing beams to add stiffness
Usage Areas
Employed in composite floor systems, mezzanines, car parks, industrial buildings, and bridge decks; suitable for new builds and refurbishment where speed, reduced propping, and integrated reinforcement are desired.
