China Profiled Steel Deck Suppliers - High-Strength Composite Floor Deck from Leading Factory
1Product Overview
The Profiled Steel Deck, also known as composite floor deck or metal roof deck, is a high-strength, cold-formed structural component roll-formed from galvanized steel coils. It serves a dual purpose in modern construction: acting as a permanent formwork for concrete slabs during the pouring stage and functioning as a positive reinforcement in the finished composite floor system. Its unique trapezoidal or re-entrant rib profile provides excellent structural performance, making it an indispensable element in high-rise buildings, industrial plants, and large-span infrastructure projects.
2Key Features & Advantages
The optimized rib geometry delivers an exceptional strength-to-weight ratio. The embossments (webs) on the ribs provide a mechanical interlock with concrete, ensuring composite action and enhancing the structural integrity of the floor slab.
Lightweight and easy to handle, our profiled decks allow for rapid coverage of large areas. The interlocking side laps create a secure platform for workers, reducing installation time by up to 30% compared to traditional reinforced concrete methods.
By eliminating the need for traditional timber formwork and reducing the amount of onsite rebar placement, it significantly lowers labor costs and material waste. The deck itself acts as the tensile reinforcement, streamlining the supply chain.
Made from high-quality Zinc-coated (Galvanized) or Zinc-aluminum coated steel (e.g., AZ150), it offers superior corrosion resistance and can achieve up to 120 minutes of fire resistance when used in composite slabs with proper concrete cover.
Suitable for a wide range of spans and slab depths. The decking also creates a flat, clean ceiling profile below, which can be left exposed for an industrial aesthetic or easily fitted with services.
