The YX76-323-970 steel floor deck panel, also known as a galvanized floor deck, steel floor decking, or corrugated steel sheet, is a cold-formed structural steel product widely used in modern steel construction. Manufactured by roll-forming galvanized steel sheets, this deck panel features a profile height of 76mm, a rib pitch of 323mm, and an effective coverage width of 970mm. It is designed to function as a permanent formwork and composite reinforcement in cast-in-place concrete floor systems.
Originally developed as roofing sheets for industrial facilities, profiled steel sheets have evolved into specialized floor deck systems, such as the YX76-323-970 floor deck, for use in high-rise buildings, transportation terminals, commercial spaces, and public venues. Its unique profile enhances mechanical bonding with concrete and delivers excellent load-carrying performance.
High Load-Bearing Strength: The 76mm deep ribbed profile significantly increases section modulus, allowing the deck to support concrete weight and live loads during construction.
Quick and Efficient Installation: Suitable for fast-paced construction environments. The panel acts as a working platform and permanent formwork, reducing the need for scaffolding or timber formwork.
Excellent Composite Performance: After the concrete sets, the steel deck becomes part of the slab, enhancing shear resistance and overall floor stiffness.
Galvanized Corrosion Protection: Made from hot-dip galvanized steel, ensuring long-term durability even in high-humidity or coastal conditions.
Custom Lengths Available: Panels can be fabricated to project-specific lengths, minimizing on-site waste and installation time.
