Narayani GI Structural Decking Sheets | 0.80mm to 1.20mm Thickness | High-Rib Composite Floor System | Permanent Formwork for Reinforced Concrete Slabs
Narayani GI Decking Sheets are high-strength, cold-rolled galvanized steel profiles designed specifically for composite floor slab construction. These sheets feature a high-ribbed trapezoidal profile with structural embossments on the ribs to enhance the mechanical bond between the steel and the concrete. Functioning as a permanent formwork, the decking sheet supports the weight of wet concrete and construction loads, eventually acting as the external tensile reinforcement for the cured slab. The provided technical data specifies a precision-engineered profile with a 47mm rib height and a coverage width of 960mm, manufactured from a 1220mm blank size. This structural logic significantly reduces the volume of concrete required and eliminates the need for traditional timber shuttering, accelerating construction timelines for multi-story buildings and industrial mezzanines.
