Decking Sheet Work In Vasundhara Sc-19 Ghaziabad

Here’s a detailed explanation and checklist for Decking Sheet (Dacking Sheet) Work, often used in roofing, mezzanine floors, or composite slab construction in commercial and industrial buildings. 🧱 1. What Is a Decking Sheet? A decking sheet (also called metal deck sheet) is a corrugated galvanized steel sheet used as: Permanent shuttering for reinforced concrete slabs, or Roof/floor covering in industrial sheds, high-rise buildings, and commercial structures. It provides structural strength, formwork support, and durability. ⚙️ 2. Types of Decking Sheets Type Description Common Use Galvanized Decking Sheet (GI) Zinc-coated for corrosion resistance Floors, mezzanine slabs Color Coated Decking Sheet Polyester or PVDF coating for aesthetic & durability Roofing, façade Embossed Deck Sheet Anti-slip surface Composite floors Aluminum Decking Sheet Lightweight, corrosion-free Marine or chemical areas 🧩 3. Technical Specifications Thickness: 0.8 mm to 1.5 mm Width (effective): 600 mm – 1000 mm Length: Custom as per site (usually 2 m – 12 m) Yield Strength: 240–550 MPa Material: Galvanized steel (zinc-coated 120–275 GSM) Profile Depth: 44 mm, 50 mm, 76 mm (varies by brand) 🏗️ 4. Decking Sheet Work Process 🔹 Step 1: Site Preparation Verify structural steel frame alignment Ensure beam spacing matches sheet layout Clean and level all support members 🔹 Step 2: Material Handling Inspect sheets for bends or rust Store sheets on a flat, elevated surface Handle with gloves to avoid coating damage 🔹 Step 3: Sheet Laying Position sheets perpendicular to beams Maintain overlap (minimum 50–100 mm) Align ribs for uniform look and load transfer Mark and cut sheets using appropriate tools 🔹 Step 4: Fixing & Fastening Fix sheets to beams using self-drilling screws (SDST) Use washers with neoprene seals for waterproofing Provide side-lap stitching screws at regular intervals Install shear studs (if composite slab work) 🔹 Step 5: Reinforcement & Concreting (for composite slabs) Place reinforcement mesh or bars over the sheets Install spacers and maintain cover thickness Pour concrete evenly and vibrate gently to avoid deformation 🧱 5. Materials & Accessories Decking sheets (GI / Color coated) Self-drilling screws with washers Shear studs (for RCC composite slab) Reinforcement bars (TMT) Concrete (as per structural design) Edge formwork and safety barricades 🧰 6. Tools & Equipment Measuring tape and chalk line Power drill and screw gun Sheet cutting tools (nibbler or shears) Safety harnesses and helmets Welding machine (for shear studs) 🔒 7. Safety Measures Workers must wear PPE (gloves, helmet, safety shoes, harness) Use scaffolding and lifelines for high-level work Handle sheets carefully to prevent injury from sharp edges Ensure sheets are not walked on before proper fixing 📋 8. Inspection Checklist Item Checkpoint Sheet quality Thickness, galvanization, straightness Alignment Proper overlap and rib direction Fixing Adequate screw spacing and tightening Stud welding As per structural drawing Reinforcement Correct placement and spacing Concrete pour Even spreading without sheet displacement 🧾 9.
