Product Description

Product Description

Fire-Resistant Closed Ribe Floor Decking

Fire-resistant closed ribe floor decking is a kind of composite building component that pre-fills the fireproof material (rock wool/fireproof cotton) in the closed rib cavity of the profiled steel plate, and realizes the integrated solution of structural load-bearing and fireproof protection through the triple synergy of "steel-fireproof-concrete", which is widely used in high-rise buildings, commercial complexes, industrial plants and other places with strict requirements for fire rating.

Key Features

Superior Fire Resistance:

Achieves 1.5–3 hours of fire resistance (per GB 50016/ASTM E119) without additional sprays;
Rock wool (melting point >1000°C) and fireproof cotton (A1 non-combustible) block heat transfer;

Corrosion Protection:

Closed ribs prevent moisture ingress, reducing rust risk (vs. open-rib decks);
Ideal for humid/coastal environments when combined with Galvalume coating (AZ150);

Structural Efficiency:

Acts as permanent formwork, eliminating the need for temporary shoring;
Composite action with concrete enhances load capacity (up to 10 kN/m²);

Noise & Thermal Insulation:

Rock wool filler reduces sound transmission (STC ≥50) and improves thermal performance (U-value: 0.04 W/m·K);

Faster Construction:

No post-installation fireproofing required (e.g., spray coatings), saving 20–30% time.

Applications

High-Rise Buildings: Core tubes, escape staircases (meets R120+ fire ratings for evacuation routes);

Industrial Facilities: Power plants, chemical factories (resists high temperatures + chemical corrosion);

Underground & Parking Structures: Protects structural steel in garages/tunnels (fireproofing + reduced concrete thickness);

Public Spaces: Hospitals, schools, shopping malls (complies with strict fire codes like NFPA 101).
