High-Strength Profiled Steel Deck / Composite Floor Deck from China Suppliers - Quality Factory Manufacturer
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.

Frequently Asked Questions
What is the primary function of a Profiled Steel Deck in construction?
The Profiled Steel Deck serves a dual purpose: it acts as a permanent formwork for concrete slabs during the pouring phase, and it functions as positive reinforcement in the final composite floor system.
How does the steel deck improve installation speed?
Because our profiled decks are lightweight and easy to handle, they allow for rapid coverage of large areas. The interlocking side laps create a secure working platform, reducing overall installation time by up to 30% compared to traditional reinforced concrete methods.
What steel grades and thicknesses are available?
We manufacture profiled decks using structural steel grades such as S250GD, S350GD, S390GD, or ASTM A653M Gr.340 with Zinc or Zinc-aluminum coatings. The available thickness ranges from 0.8mm to 1.5mm depending on engineering requirements.
What is the difference between Trapezoidal and Re-entrant profiles?
Trapezoidal profiles (e.g., YX76-305-915) offer high stiffness and are ideal for mid-to-long span applications. Re-entrant profiles (e.g., YX50-185-740) provide a flat soffit and deliver excellent acoustic performance.
Do your profiled steel decks comply with international standards?
Yes, all of our products are manufactured in strict accordance with leading international standards, including ASTM (American Society for Testing and Materials), BS (British Standards), and Eurocodes.
What is Honglu Group's production capacity for steel structures?
Honglu Group operates 10 production sites and over 400 production lines, with a daily capacity exceeding 15,000 tons. Our annual production capacity reaches 5,000,000+ tons of steel structures and 30,000,000㎡ of slabs.
