Dacking Sheet Work In Gyan Khand Ghaziabad

Got it 👍 — you’re referring to Decking Sheet (or Deck Sheet) Work, which is commonly used in civil and structural construction, especially for composite slabs, mezzanine floors, and roofing systems. Here’s a complete overview 👇 🏗️ Decking Sheet Work (Steel Deck Sheet / Roof Deck Sheet) 🔹 1. What is a Decking Sheet? A decking sheet is a corrugated galvanized steel sheet used as a permanent shuttering (formwork) during casting of reinforced concrete slabs. It serves dual functions: Acts as formwork for wet concrete. Becomes a tensile reinforcement in the slab after hardening. 🔹 2. Common Applications Multi-storey buildings (composite slabs) Mezzanine floors in industrial buildings Roof decking for steel structures Bridges and warehouses Parking areas and commercial complexes 🔹 3. Technical Specifications Parameter Typical Value Material Galvanized Steel (GI) Thickness 0.8 mm – 1.6 mm Width 900 mm – 1250 mm Length Custom (as per design) Yield Strength 240–550 MPa Finish Zinc-coated / Galvalume Coating Thickness 120–275 GSM 🔹 4. Types of Decking Sheets GI Decking Sheet (Galvanized Iron) – Most common for slabs. Color Coated Decking Sheet – Used for aesthetic roofs. Embossed Decking Sheet – For improved bond with concrete. Aluminium Decking Sheet – Lightweight roofing applications. 🔹 5. Advantages ✅ Quick installation and reduced slab casting time. ✅ Eliminates need for separate shuttering and scaffolding. ✅ High load-bearing capacity. ✅ Reduces concrete and reinforcement steel consumption. ✅ Clean underside finish – ideal for industrial interiors. ✅ Fire-resistant when properly designed with concrete topping. 🔹 6. Installation Procedure Mark layout and support positions. Place decking sheets on steel beams or joists with correct overlap. Fix with self-drilling screws or welding. Ensure proper alignment and end bearing (usually 50–100 mm). Place reinforcement mesh on top (as per structural design). Pour concrete carefully — avoid overloading during casting. Cure the concrete properly for at least 7 days. 🔹 7. Accessories & Fasteners Self-tapping screws / welding studs End caps and edge trims Shear studs (for composite action) Support brackets and sealants 🔹 8. Safety & Quality Checks Verify sheet thickness and zinc coating. Check alignment and overlaps. Ensure adequate end bearing and screw tightness. Avoid walking directly on sheets before fixing. 🔹 9.
