Welded Steel Grating: Material & Construction
- Premium Material Options:
- Carbon Steel (ASTM A36/A1011): Hot-rolled or cold-rolled options with yield strength ≥250 MPa for heavy industrial platforms or truck docks.
- Hot-Dip Galvanized Steel (ASTM A123): 85–100 µm zinc coating for water treatment plants or coastal walkways (salt spray resistance: 1,500+ hours).
- Stainless Steel 304/316L (ASTM A480): Ideal for chemical processing or food-grade facilities (PREN ≥18–25, Ra ≤1.6 µm finish).
- Engineered Welding Techniques:
- Electric Resistance Welding: Uniform crossbars (±1.5 mm tolerance) for OSHA-compliant load distribution (EN 1433:2002).
- Press-Locked Construction: Interlocked bearing bars for zero-slip performance in refinery stair treads or parking garages.
- Custom Configurations:
- Panel Sizes: Standard 1m x 6m or custom-cut for tight industrial spaces (thickness: 3–10 mm).
- Surface Treatments: Serrated or grit-coated surfaces (DIN 51130 R10–R13 slip resistance) for oil rigs or frost-prone walkways.
Welded Steel Grating: Performance Advantages
- Exceptional Load Capacity:
- Heavy-Duty Ratings: Supports 10–40 kN/m² (EN 1991-1-1) for warehouse mezzanines or airport tarmacs.
- Impact Resistance: Withstands ASTM E23 Charpy tests (≥27 J at -20°C) for mining conveyor platforms or logistics hubs.
- Corrosion & Wear Resistance:
- Galvanized Longevity: 25+ years in humidity-rich environments (ISO 9227 compliant).
- Abrasion-Resistant Coatings: Epoxy or polyurethane finishes (ISO 12944 C4/C5) for steel mills or wastewater facilities.
- Safety & Compliance:
- SlipGuard Design: Meets OSHA 1910.23 for open riser stairs or catwalks.
- Toe Plates & Trim: OSHA-compliant edges to prevent tripping hazards in public infrastructure.
Welded Steel Grating: Precision Manufacturing & Testing
- Advanced Fabrication:
- Robotic Welding (AWS D1.1): Ensures full-penetration joints for high-traffic pedestrian bridges or factory floors.
- Laser-Cut Edges: Precision (±0.5 mm) for seamless alignment in modular platforms or retrofit projects.
- Rigorous Quality Assurance:
- Load Deflection Tests (EN 1990): Validates ≤L/200 deflection under 1.5x design load (e.g., 30 kN/m²).
- Coating Adhesion Tests (ASTM D3359): Ensures ≥4B rating for long-term corrosion protection.
- Dimensional Checks: Verified flatness (±2 mm/m²) for ADA-compliant ramps (ANSI A117.1).
Welded Steel Grating: Industry Applications
- Oil & Gas:
- Offshore Platform Flooring: Galvanized grating with R13 slip resistance (NORSOK M-501 compliant).
- Refinery Walkways: Stainless steel 316L grating for acidic fume resistance (ASTM G48 certified).
- Water & Waste Management:
- Treatment Plant Platforms: Epoxy-coated grating for chlorine-rich environments (ISO 12944 C5-M).
- Pump Station Grating: Aluminum-bearing bar alternatives for lightweight maintenance access.
- Transportation & Infrastructure:
- Railway Station Platforms: Press-locked grating with anti-vandal design (EN 1433:2002).
- Highway Drainage Covers: Heavy-duty carbon steel grating (40 kN/m²) for HS25 vehicle loads.
- Commercial & Industrial:
- Warehouse Mezzanines: Hot-dip galvanized grating (6mm thickness) for pallet jack traffic.
- Food Processing Catwalks: 304 stainless steel with hygienic electropolish (FDA compliance).
- Renewable Energy:
- Wind Turbine Access Grating: Galvanized panels with non-slip serrations (IEC 61400-22 certified).
- Solar Farm Walkways: Lightweight aluminum grating for UV-resistant maintenance paths.
