High-Strength Profiled Steel Deck | Composite Floor Deck from China Suppliers and Factory
Product 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.
Key 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.
Technical Specifications
- Material: Structural Steel Grade (e.g., S250GD, S350GD, S390GD, or ASTM A653M Gr.340) with Zinc/Zinc-aluminum coating.

Frequently Asked Questions (FAQ)
What is a Profiled Steel Deck and how is it used?
A Profiled Steel Deck is a high-strength, cold-formed structural component made from galvanized steel coils. It serves as permanent formwork for concrete slabs during construction and provides positive reinforcement in the final composite floor system.
What are the main structural advantages of composite floor decks?
It offers a high load-bearing capacity due to optimized rib geometry, fast and safe installation that reduces labor time by up to 30%, cost-effective elimination of temporary timber formwork, and excellent durability with up to 120 minutes of fire resistance.
What steel grades and thicknesses are available for the profiled deck?
We supply structural steel grades such as S250GD, S350GD, S390GD, or ASTM A653M Gr.340 with Zinc or Zinc-aluminum coatings, in thicknesses ranging from 0.8mm to 1.5mm depending on engineering requirements.
