The ComFlor 210 Alternative Deep Composite Floor Decking is a high-performance structural flooring system tailored for large bay-width steel-framed buildings. Featuring a specialized deep profile, it enables wider column spacing to create spacious, column-free interior areas while drastically reducing the number of supporting beams. Manufactured from premium high-strength galvanized steel, it delivers outstanding long-span capability, stable concrete composite action and dependable fire resistance. Highly versatile, it is widely applicable for commercial high-rises, parking structures and industrial facilities, perfectly accommodating construction projects requiring flexible and extended bay-width designs.

Extended Bay Widths – Maximizing Design Flexibility​

ComFlor 210 Alternative deep deck profile achieves longer spans between supporting beams, allowing engineers to adopt wider column grids and flexible floor plates. Lifting internal column quantities expands usable space and improves layout freedom. The optimized rib geometry and integral stiffeners supply sufficient rigidity for long spans with economical material consumption.
Material Quality & Corrosion Protection​
Produced from high-strength galvanized steel with guaranteed minimum yield strength, ComFlor 210 Alternative maintains stable structural performance in harsh construction environments. The heavy-duty zinc coating offers full corrosion protection, preserving structural integrity during construction and long-term operation. The durable surface avoids extra anti-corrosion treatment, lowering initial investment and maintenance costs.​
Technical Specifications​​

Integrated Service Routing – Optimizing Floor Zones​​
The ComFlor 210 Alternative features a deep profile that allows all building MEP services to be installed within the deck ribs and fully concealed inside the slab depth, rather than beneath the floor structure. This unique design effectively reduces overall floor zone height, maximizes clear floor-to-ceiling space, and simplifies coordination between structural and MEP engineering teams. By optimizing vertical space utilization, it delivers superior spatial efficiency and is perfectly suited for all types of multi-storey building construction.
Structural Efficiency & Composite Action​​
Equipped with integrated cross and longitudinal stiffeners, the ComFlor 210 Alternative delivers exceptional structural efficiency and stable composite performance with cast-in-place concrete slabs. Acting as permanent formwork during construction and serving as continuous tensile reinforcement for the finished floor system, the deck ensures uniform concrete coverage and standardized rebar layout. This optimized profile reliably meets structural strength and fire resistance requirements. Compared with conventional flooring solutions, its superior composite performance enables longer clear spans while significantly reducing both steel and concrete consumption.
Fire Performance – Proven Protection​​​​​
ComFlor 210 Alternative possesses inherent fire resistance. It reaches a 60-minute fire rating without fire protection on steelwork or deck. Proper slab thickness and reinforcement arrangement help achieve ratings of up to 2 hours with unprotected soffit. Fire design takes tensile performance of trough reinforcement and surface anti-crack mesh into consideration, meeting mainstream international building code requirements.
Construction Efficiency & Site Benefits​​

ComFlor 210 Alternative deep deck supports fast on-site installation. Panels are lightweight for easy handling while retaining long-span structural capacity. The deck forms an immediate safe working platform for follow-up construction works. Nestable profile cuts transportation volume and logistics cost, and the 50mm minimum end bearing simplifies positioning on supporting steel structures.
Why Choose ComFlor 210 Alternative ​for Extended Bay Width Projects?​​

Ideal for projects requiring wider column spacing, flexible floor layouts and shallow structural depth, the ComFlor 210 Alternative Deep Composite Decking serves as a highly reliable structural solution. Combining superior long-span capability, integrated MEP service routing and up to 2-hour fire resistance, the system fully satisfies modern building standards for structural stability, design flexibility and construction efficiency.
