Product Description

Product Description

Fire-Resistant Closed Ribe Floor Decking

Fire-resistant closed rib floor decking is a composite construction element that integrates fireproof material (rock wool/fireproof batting) into the ribbed cavity of profiled steel sheets. By leveraging the synergistic effect of "steel-fireproofing-concrete", it provides a combined structural load-bearing and fire protection solution. This system is widely used in high-rise buildings, commercial complexes, industrial plants, and other structures with stringent fire safety requirements.

Key Features

Superior Fire Resistance:

Achieves 1.5–3 hours of fire resistance without additional sprays;
Rock wool and fireproof cotton block heat transfer;

Corrosion Protection:

Closed ribs prevent moisture ingress, reducing rust risk;
Ideal for humid/coastal environments when combined with Galvalume coating;

Structural Efficiency:

Acts as permanent formwork, eliminating the need for temporary shoring;
Composite action with concrete enhances load capacity;

Noise & Thermal Insulation:

Rock wool filler reduces sound transmission and improves thermal performance;

Faster Construction:

No post-installation fireproofing required, saving 20–30% time.

Applications

High-Rise Buildings: Core tubes, escape staircases;

Industrial Facilities: Power plants, chemical factories;

Underground & Parking Structures: Protects structural steel in garages/tunnels;

Public Spaces: Hospitals, schools, shopping malls.
