Product Description
-
As an alternative to ComFlor® 210, this deep long-span composite floor deck fits Slimflor® & Slimdek® systems. Fabricated from S280GD+Z275 hot-dip galvanized steel (BS EN 10346), it features 350 N/mm² minimum yield strength and 275g/m² double-sided zinc coating, delivering robust strength and anti-corrosion performance for indoor and semi-exposed projects. Its 210mm deep rib with bidirectional stiffeners enhances structural efficiency and cuts steel & concrete usage. It achieves 6m unpropped spans and 9m propped spans, reducing temporary supports and shortening construction schedules. Certified to BES 6001, standard EPD documents are available.
Material Performance
Made of premium hot-dip galvanized steel complying with BS EN 10346:- •Steel grade: S280GD+Z275, minimum yield strength: 350 N/mm²
- • Zinc coating: 275g/m² on both sides for long-term anti-rust protection
- •High strength-to-weight ratio realizes longer spans with less steel dosage, widely used in commercial and industrial buildings
Core Specifications & Advantages
| Attribute | Specification | Core Advantage |
|---|---|---|
| Material Grade | S280GD+Z275 galvanized steel, 350 N/mm² yield strength, 275g/m² zinc coating, BS EN 10346 standard | High strength reduces steel consumption; thick zinc coating delivers durable anti-corrosion effect |
| Profile Geometry | 210mm deep trapezoidal rib, dual stiffeners, 600mm covering width | Prominent structural efficiency lowers concrete usage; broad top surface serves as safe working platform |
| Span Capacity | 6.0m unpropped span; 9.0m propped span, single-span design during construction | Fewer temporary supports required, shortens construction period and reduces labor cost |
| Fire Property | 2-hour fire resistance with bare soffit, equipped with single reinforcement and anti-crack mesh | No extra fireproof coating needed, simplifies design and lowers overall project expenditure |
| Sustainable Certifications | BES 6001, verified EPD (ISO 14025) | Qualified for LEED, BREEAM green buildings and global infrastructure bidding projects |
| System Matching | Designed for Slimdek®/Slimflor®, installable on asymmetric beam bottom flange or conventional beam top flange | Slim floor design shrinks building height and adds extra floors for high-rise projects; convenient pipeline layout |
Fire Resistance Feature
Optimized rib structure and reinforcement layout enable 2 hours fire resistance without soffit fireproof paint, satisfying commercial, educational and medical building codes. It achieves 60-minute fire protection easily with encastre beams. Equipped with anti-crack mesh as BS 5950 standard, the slab keeps stable structural performance under fire conditions.
Slim Floor System Application
Mounted on the bottom flange of asymmetric beams, the floor slab is embedded within beam depth to bring multiple benefits:
- •Cut overall building height and add one extra floor for buildings above 10 storeys
- •Reduce exterior wall cladding costs
- •Arrange pipelines inside slab ribs to save indoor vertical space It also fits traditional beam installation modes for diversified engineering designs.
Concrete Allocation
Applicable slab thickness ranges from 260mm to 400mm. The optimized rib shape consumes less concrete than ordinary floor decks, effectively reducing foundation load and main steel weight. Adjustable slab thickness adapts to office light loads and industrial heavy loads flexibly.
Export & Logistics Benefits
The nestable trapezoidal profile greatly increases loading volume per bundle and shipping container to cut transportation expenses. A two-person team can lay over 400 m² per day; hoisting and concrete pouring proceed efficiently to speed up project delivery, delivering remarkable cost advantages for global export orders.
Summary
As an alternative to ComFlor 210, this long‑span galvanized composite floor deck serves multi‑story building projects. Made of S280GD+Z275 Grade 350 hot‑dip galvanized steel, it features durable anti‑corrosion property, 6m unpropped span, 9m propped span and 2‑hour bare soffit fire resistance. Equipped with global sustainability certifications and nestable shipping structure, it effectively lowers export logistics expenses. Matched with the Slimflor slim floor system, it optimizes space planning and total project cost, offering stable performance for engineers and contractors.

Fire Resistance Performance
With optimized rib structure and reinforcement layout, ComFlor 210 achieves 2-hour fire resistance without soffit fireproof paint, fitting commercial, education and medical building codes. It reaches 60-minute fire protection effortlessly with encastre beams. Anti-crack mesh configured as BS 5950 and Eurocode 4 standards maintains slab stability under fire conditions.
Slim Floor System Application
Installed on the bottom flange of asymmetric beams, the floor slab is contained within beam depth to bring multiple benefits:
- Reduce total building height and add one extra floor for 10+ storey buildings
- Cut exterior cladding costs
- Conceal mechanical services inside slab ribs to save indoor vertical space It also adapts to traditional beam layouts for flexible engineering designs.
Concrete Allocation & Slab Size
Applicable slab depth: 260mm–400mm. Its streamlined rib structure consumes less concrete than ordinary floor slabs and lessens foundation load and main steel weight. Adjustable slab thickness accommodates office light loads and industrial heavy loads flexibly.
Export & Logistics Merits
The nestable trapezoidal shape raises loading quantity per bundle and container to lower transportation fees. Two workers can lay over 400 m² per day; hoisting and concrete pouring proceed rapidly to accelerate project progress, delivering prominent cost edges for global export orders.
