ICF(Insulated Concrete Form) Bracing
ComFlor 60 equivalent heavy galvanized deck for bridges and high-rise buildings
The ComFlor 60 Equivalent Composite Steel Floor Decking is a high-performance, heavy galvanized floor deck system engineered for steel bridges and high‑rise building construction. This profile combines a trapezoidal section with a dovetail re‑entrant design, delivering exceptional spanning capabilities, reduced concrete usage, and superior fire performance. Manufactured from G500 galvanized steel with a minimum yield stress of 500 N/mm² and Z275 zinc coating (275 g/m² total both sides), this decking provides outstanding durability and corrosion resistance for demanding structural applications. All profile dimensions and specifications are fully customizable to meet project-specific requirements.
Superior Spanning Capability
The optimized profile design offers exceptional unpropped spanning capability for double‑span construction. Propped spans can reach even greater distances, significantly reducing the number of support beams required. This longer span capability broadens beam spacing, accelerates erection timelines, and delivers substantial cost savings on supporting steelwork. Specific span data is available upon request based on your project parameters.

Material Specifications & Durability
| Category | Detailed Technical Data |
|---|---|
| Material & Coating | Steel grade: G500 cold‑formed steel complying with AS 1397, with a guaranteed minimum yield stress of 500 N/mm². Zinc coating: Hot‑dip galvanized Z275 (total coating mass 275 g/m² both sides), ensuring superior corrosion resistance for exposed and internal structural environments. Customizable: Steel grades and coating weights can be tailored to project requirements. |
| Profile Geometry | Trapezoidal profile with integrated dovetail re‑entrant design enables quick suspension of ceilings and MEP services using wedge‑nut or squeeze‑type hangers (safe working load up to 3.0kN per fixing). Fully customizable: Rib height, cover width, pitch and overall profile dimensions can be engineered to your exact specifications. |
| Structural Performance | Multiple thickness options available to suit different load requirements. The profile delivers excellent moment capacity and stiffness, with unpropped double‑span capacity up to 4.5m and propped spans up to 6.8m with temporary supports. Customizable: Thickness, steel area, moment of inertia and load-bearing capacity can all be engineered to order. |
| Fire & Acoustic | Fire resistance: Tested to BS 5950 Part 8 with ratings up to 4 hours. Design options include the Simplified Fire Method or the Fire Engineering Method. The rib profile also contributes to enhanced acoustic insulation (STC data available on request) and improved vibration damping. Customizable: Fire rating and acoustic performance can be optimized per project needs. |
Fire Resistance & Acoustic Performance
ComFlor 60 equivalent decking achieves fire ratings of up to 4 hours. The optimized profile height allows for a reduced overall slab depth while maintaining required fire insulation. The system also delivers excellent inherent acoustic properties, making it suitable for noise‑sensitive applications such as residential apartments, hospitals, and office buildings. Fire design can be calculated using either the Simplified Fire Design Method or the Fire Engineering Method.

Optimized Composite Action
The profile has been specially designed with trough stiffeners and side laps positioned to guarantee centrally placed shear studs. This centralized stud position ensures optimum capacity of the shear connectors, enhancing composite action while reducing the need for on‑site checking of stud location. Standard shear studs are suitable for use with this decking system.

Reduced Concrete Volume & Slab Depth
The profile design minimizes the concrete volume required for any slab depth. The optimized profile shape effectively reduces slab depth, resulting in lower overall floor height, reduced dead loads on the structure and foundations, and savings on the total building cost.

Ease of Installation & On‑Site Safety
The decking sheets are designed for lightweight handling and easy installation, delivering significant on‑site safety benefits. The dovetail re‑entrant allows for quick and easy suspension of ceilings and services using low‑cost hanger fixings. Wedge nut fixings provide a safe static working load of up to 3.0kN each.
