Hebei Kaiheng’s carbon roofing sheet composite steel grating is an industrial-grade structural material, blending high-quality carbon steel with composite reinforcement. It excels in load-bearing, anti-slip, and weather resistance, making it ideal for building roofs, industrial platforms, and stair treads. Designed to meet stringent industrial standards, it balances functionality with long-term cost savings.
Parameter | Value |
Material | Carbon steel (Q235/Q355) + composite resin layer |
Grating Thickness | 20mm–80mm (customizable) |
Bearing Bar Size | 25×5mm–100×10mm (flat/serrated) |
Cross Bar Spacing | 38mm, 50mm, 76mm (standard); 100mm (custom) |
Load Capacity | 5kN/m²–50kN/m² (depends on thickness) |
Surface Treatment | Anti-rust paint, hot-dip galvanization |
Fire Rating | Class B1 (GB 8624) |
• Superior Load-Bearing: Q355 steel bearing bars handle heavy loads (e.g., 50kN/m² for 80mm-thick grating, suitable for industrial machinery).
• Anti-Slip Safety: Serrated bearing bars (surface roughness Ra 12.5μm) prevent slips in wet/dusty environments (e.g., factory floors, roof walkways).
• Weather Resistance: Composite resin layer blocks rain and UV rays; galvanized steel resists corrosion (service life ≥20 years outdoors).
• Lightweight Design: 30% lighter than solid steel plates, reducing building roof load and installation labor.
• Building Roofing: Used as roof support grids for factories/warehouses; composite layer insulates heat, lowering air-conditioning costs by 15%.
• Industrial Platforms: Applied in oil refineries and chemical plants—anti-corrosion coating resists chemical spills; open grid design allows drainage.
• Stair Treads: Serrated surface ensures worker safety in power plants; fire-resistant rating meets industrial safety standards.
• Bridge Auxiliary Structures: Lightweight grating reduces bridge load; high strength withstands vehicle vibrations.
1. Steel Cutting: CNC machines cut bearing bars/cross bars to precise lengths (tolerance ±1mm).
2. Welding: Automatic resistance welding (2000A current) ensures strong joints (shear strength ≥30MPa); no weld spatter for smooth surfaces.
3. Composite Coating: Resin layer (epoxy-based) is applied via roller coating, cured at 120°C for 2 hours to ensure adhesion.
4. Final Inspection: Load tests (simulate 120% of rated capacity) confirm performance; coating thickness measured with a magnetic gauge.
• Bearing Bar Arrangement: Parallel layout with uniform spacing; thicker bars (100×10mm) used for high-load areas.
• Edge Protection: 50×5mm steel edging bars prevent grating deformation; rounded edges reduce injury risks.
• Installation Holes: Pre-drilled holes (Φ10mm) on edging bars for easy mounting (compatible with M8 bolts).
• Design Support: Engineers create 3D models (AutoCAD/Revit) based on client building plans; optimize grating layout for load and cost.
• Installation Guidance: On-site training for installers; provide fastening accessories (bolts, washers) matching grating thickness.
• Quality Certifications: Supply ISO 9001 quality certificates and SGS test reports for each batch.
• Maintenance Tips: Annual inspection reminders; recommend anti-rust paint touch-ups for high-corrosion areas (e.g., coastal regions).
