Grating Stair Tread: Material & Construction
- Heavy-Duty Materials:
- Hot-Dip Galvanized Steel (ASTM A123): Corrosion-resistant for industrial plants or offshore platforms (coating thickness: 80–100 µm).
- Stainless Steel 304/316L: PREN ≥18–25 for chemical facilities or food processing plants (Ra ≤1.6 µm surface finish).
- Aluminum 6061-T6: Lightweight yet durable (tensile strength: 276 MPa) for maritime staircases or temporary access systems.
- Engineered Safety Features:
- Serrated or Gripper Surface: R10–R13 slip resistance (DIN 51130) for wet environments or oil & gas platforms.
- Nose Overhang (20–30 mm): OSHA-compliant design (1910.24) to prevent foot slippage on steep inclines.
- Closed-End Edges: Eliminate toe traps for ADA/ANSI A117.1 compliance in public infrastructure.
Grating Stair Tread: Performance Advantages
- Unmatched Safety:
- Slip Resistance (ASTM F1679): Achieves ≥0.68 dynamic coefficient of friction for refinery stairways or brewery catwalks.
- High Load Capacity: Supports 5–15 kN/m² for heavy equipment access or crowded pedestrian zones (EN 1993-1-1 compliant).
- Corrosion & Wear Resistance:
- Salt Spray Resistance (1,500+ hours, ASTM B117): Ideal for coastal walkways or de-icing salt exposure.
- Abrasion-Resistant Coatings: Epoxy or polyurethane finishes (ISO 12944 C5-M) for mining staircases or steel mills.
- Modular Design:
- Pre-Drilled Mounting Holes: Enables bolt-on installation for retrofitting existing stairs.
- Interlocking Panels: Seamless alignment for long-span mezzanine stairs or ship ladders.
Grating Stair Tread: Precision Manufacturing & Testing
- Advanced Fabrication:
- Robotic Welding (AWS D1.1): Ensures full-penetration joints for high-traffic stair systems.
- Laser-Cut Profiles: Precision edges (±1 mm tolerance) for snug fit in tight industrial spaces.
- Rigorous Quality Assurance:
- Load Testing (EN 1991-1-1): Validates ≤2 mm deflection under 1.5x design load (e.g., 22.5 kN/m²).
- Slip Testing (EN 1093-5): Certifies R10–R13 ratings for oil-resistant surfaces or frost-prone areas.
- Coating Thickness Checks (ISO 2178): Ensures ≥80 µm galvanization for 20+ years service life.
- Custom Solutions:
- Color-Coded Treads: Powder-coated yellow/black for hazard zone visibility (OSHA 1910.145).
- Integrated Drainage Slots: Prevent water pooling on outdoor emergency exits.
Grating Stair Tread: Industry Applications
- Oil & Gas:
- Offshore Platform Stairs: 316L stainless steel treads with serrated surfaces (NORSOK M-501 compliant).
- Refinery Access Ladders: Galvanized steel treads (R13 rating) with anti-static coatings.
- Industrial & Manufacturing:
- Factory Mezzanine Stairs: Aluminum treads (6061-T6 alloy) for lightweight maintenance access.
- Warehouse Fire Escapes: Bolt-on carbon steel treads (10 kN/m² load) with epoxy red finish.
- Public Infrastructure:
- Pedestrian Overpass Stairs: Powder-coated treads (RAL 7011 grey) with ADA-compliant nose profiles.
- Transit Station Escalators: Stainless steel treads (Ra ≤1.2 µm) for low-maintenance urban use.
- Marine & Utilities:
- Shipboard Staircases: Aluminum treads with anodized finish (MIL-A-8625F) for saltwater resistance.
- Wastewater Treatment Plants: Hot-dip galvanized treads (150 µm coating) for H₂S corrosion resistance.
