Steel Decking Sheets

-- Steady & Reliable Manufacturer --

Introduction

Steel Decking Sheets (or composite floor deck) are galvanized structural steel sheets profiled to provide formwork for concrete slabs and reinforcement after the concrete cures. Used extensively in multi-story construction, this system significantly reduces the need for conventional concrete formwork while providing immediate work platforms during construction. The dovetail/trapezoidal shape mechanically locks with the concrete, creating a highly efficient, lightweight, and durable composite slab.

We supply various profiles optimized for different span lengths and concrete thicknesses, ensuring structural integrity and cost optimization.

Specifications

Parameter	Value/Range
Base Material	Galvanized Steel (GI)
Thickness Range	0.75mm to 1.5mm
Coating Mass	Z120 to Z275 g/m2 (Protection during construction)
Steel Grade	G300 to G550 MPa (Structural Grade)
Profile Height	50mm, 75mm, 100mm, 150mm
Effective Width	600mm to 950mm (Profile dependent)
Fire Rating	Achieves required fire rating when composite with concrete.

Structural Benefit: The trapezoidal profile acts as tensile reinforcement, reducing the need for costly conventional rebar within the slab's lower section.

Application

High-Rise Buildings: Commercial offices, residential towers, and mixed-use structures.
Parking Structures: Multi-story car parks due to their high strength-to-weight ratio.
Industrial Mezzanines: Intermediate floors in factories and warehouses.
Bridges & Infrastructure: Permanent formwork for elevated roadways and support structures.

Advantages

Faster Construction Cycle: Eliminates the time and cost associated with timber or traditional temporary formwork.
Structural Efficiency: Reduces the overall weight of the slab while maintaining high load-bearing capacity.
Immediate Work Platform: Provides a safe platform for follow-on trades before the concrete cures.
Cost-Savings: Reduces the volume of concrete and reinforcing steel required in the slab.

Payment & Shipping

Project Consultation: Our engineers can assist with load tables and profile selection based on your specific slab design requirements.
Logistics: Sheets are pre-cut and stacked in transportable bundles, clearly labeled by profile and project area for easy lifting and placement on site.
Customization: We offer special end-closure pieces and custom detailing for specific column and beam integration.

Frequently Asked Questions

Q: Do I still need rebar when using steel decking?
A: Yes, a light layer of temperature/shrinkage mesh is still typically required in the concrete. The decking replaces the need for most of the bottom-layer tensile reinforcement.

Q: How are services (pipes, cables) routed through the slab?
A: Steel decking has specific designated areas, or "ribs," where temporary holes can be cut for small services before concrete pouring. Larger openings require structural consultation.
