Long-Span Composite Floor Decking – ComFlor 210 Equivalent for Slimflor Steel Structures

Our Long-Span Composite Floor Decking is a high-precision structural flooring solution professionally developed as a reliable ComFlor 210 equivalent, specially optimized for modern Slimflor steel structure construction. Featuring a standard deep closed-rib profile, this metal decking fully matches international ComFlor 210 specification standards, enabling rapid on-site installation while minimizing overall structural floor depth.

Integrated cross and longitudinal stiffeners significantly enhance mechanical stability, forming strong composite bonding with cast-in-place concrete slabs. Serving as permanent structural formwork, the deck bears wet concrete loads during construction and acts as continuous tensile reinforcement after slab curing. It delivers an efficient, low-maintenance, and highly cost-effective flooring solution for large-span commercial and industrial building projects.
 

1. Professional Design for Slimflor Steel Structures​​

This decking system is tailor-made for Slimflor integrated beam construction. The steel deck fits perfectly on the extended bottom flange of slim steel beams, fully embedded within the beam depth. This mature structural design effectively reduces total building floor height, creates clear service voids under the floor slab, and allows full integration of electrical, HVAC and plumbing systems inside the floor zone.

By optimizing the overall floor assembly thickness, our long-span decking greatly reduces the building envelope volume, lowering foundation and enclosure costs. It is highly suitable for high-rise commercial buildings, residential complexes and large public infrastructure projects.
 

2. Superior Spanning Capacity & Structural Efficiency​​

As a high-performance deep-rib deck profile, our ComFlor 210 equivalent boasts outstanding spanning performance. With a maximum steel gauge of 1.25mm, the system achieves unpropped spans up to 6 metres, and over 8.5 metres for propped construction scenarios.

Ultra-long spanning capability drastically reduces the layout density of intermediate secondary steel beams and eliminates extensive temporary shoring systems. It accelerates construction progress, simplifies on-site workflows, and effectively cuts overall steel consumption and comprehensive project costs.
 

3. Technical Specifications​​

All parameters support full customization to meet project-specific load grades, span limits and environmental conditions.

4. Concrete Optimization & Comprehensive Cost Reduction​​

The unique deep-rib profile structure greatly improves material utilization efficiency and reduces concrete consumption significantly. A 270mm composite slab with our ComFlor 210 equivalent only consumes concrete equivalent to a 115mm solid slab; a 350mm deep slab equals a 195mm solid slab in concrete volume.

Reduced concrete dosage lowers the permanent dead load of the entire building structure, optimizing primary steel beam and column specifications, and further saving foundation engineering costs. It achieves dual cost savings of material consumption + structural optimization.
 

5. Service Integration & Reliable Fire Resistance​​

The 210mm deep rib void provides reserved space for centralized arrangement of building services, including electrical pipelines, air-conditioning ducts and drainage systems. It eliminates the need for additional suspended ceilings, simplifying interior decoration and improving indoor space utilization.

This composite deck system features excellent natural fire resistance, achieving 60-minute fire rating without additional fireproof coating on steel decks. With unprotected soffit design, the fire resistance can reach up to 2 hours, fully meeting international building fire protection standards.
 

6. Precision Manufacturing & Strict Quality Control​​

We adopt advanced continuous CNC roll-forming production lines with ultra-tight dimensional tolerances to ensure 100% profile consistency with standard ComFlor 210. Before mass production, all steel coils undergo strict inspection of thickness, zinc coating weight and yield strength.

Multi-stage finished-product inspections including profile geometry detection, surface quality screening and dimensional calibration ensure perfect on-site fitting, stable composite structural performance and zero construction rework risks.
 

7. Standardized Packaging & Global Export Shipping​​

Professional seaworthy packaging protects profile integrity and galvanized finishes during long-distance ocean transportation:

• Compact Bundling: Nestable deep-rib design enables tight stacking and compact bundling, effectively reducing transportation volume and freight costs. Panels are fixed with heavy-duty steel straps and wrapped with moisture-proof barrier film.
• Container Optimization: Custom cut lengths maximize 20ft/40ft container loading rate to lower unit freight cost.
• Unified Marking: All bundles are clearly labeled with batch numbers, dimensions and shipping marks for fast customs clearance and on-site inventory management.
   

8. Full-Cycle After-Sales & Technical Support​​

We provide one-stop full-lifecycle project support for global clients:

• Professional Technical Consultation: Structural engineers provide accurate span calculation, composite slab design optimization and connection detail guidance.
• On-Site Installation Guidance: Optional field installation supervision to ensure standard placement, fixing and composite structural effectiveness.
• Complete Quality Documents: Full mill test certificates and material traceability reports are provided with every shipment.
• Auxiliary Material Support: Stable supply of matching high-strength fasteners, sealants and repair touch-up coatings for after-sale maintenance.
