Product Description

Product Description

Closed Rib Profiled Steel Decking

Closed Rib Profiled Steel Decking is formed by cold-rolling galvanized steel sheets into interlocking trapezoidal profiles with sealed ribs. It functions as permanent formwork during construction and achieves full composite action with cast-in-place concrete through mechanical interlock.

Key Features

Economic:

Reduces formwork costs by 80% compared to timber systems (per NIST studies);
Eliminates concrete leakage (saving 15% material waste, CIRIA Report 141);

Structural Efficiency:

Enables unpropped spans up to 4.5m (25% longer than open-rib decks, SDI-C 2021);
Achieves 30% higher composite shear capacity (EN 1994-1-1 Annex B);

Durability:

Standard hot-dip galvanizing (Z275–Z600 per ISO 1461);
Optional epoxy-polyester hybrid coatings for harsh environments (ISO 12944 C4).

Applications

Data Centers: Supports 7.5 kN/m² live loads with 200mm concrete (Uptime Institute Tier III)
Hospitals: Vibration frequency >9Hz (HTM 05-02 compliance)
Parking Structures: Chloride resistance with Class C galvanizing (ASTM A123)

Technical Compliance

Material: G550 (AS 1397) / S420MC (EN 10149-2)
Design: EN 1994-1-1 (EU) / SDI-C 2021 (US)
Fire Rating: 120mins unprotected (BS 476-21 tested)
