Steel Grating: High-Strength, Anti-Slip for Global Industrial & Construction Applications

🌟 Core Features: Why Global Projects Choose Our Steel Grating

✅ Premium Material & Global Standard Compliance

• High-Quality Material Options: We offer steel grating in carbon steel (Q235, Q355) and stainless steel (304, 316L). Carbon steel balances cost and strength, ideal for European and Asian industrial plants; 304 stainless steel provides excellent corrosion resistance for food processing and coastal areas; 316L excels in salt spray and chemical resistance, perfect for Southeast Asian marine projects and North American pharmaceutical factories (complies with FDA standards). Bar thickness ranges from 3mm to 12mm, and pitch sizes from 20mm to 100mm, adapting to various load requirements 13.
• Comprehensive Global Certifications: All steel grating products pass strict quality inspections, meeting EU CE, US UL, ISO 9001, ISO 14001, and EN 10045 standards. Load-bearing test reports (SGS/Intertek certified) and material certificates ensure hassle-free customs clearance and project acceptance in 120+ countries 25.

✅ Exceptional Structural Strength & Safety

• Superior Load-Bearing Capacity: Adopting high-strength bearing bars and cross bars, our steel grating achieves a maximum load capacity of 50kN/m² (for heavy-duty models), suitable for industrial equipment platforms, vehicle ramps, and shipping docks. The welded joint design (argon arc welding or resistance welding) ensures strong bonding, with shear strength ≥300MPa 46.
• Reliable Anti-Slip Performance: The bearing bars feature serrated or raised surface designs, providing a high friction coefficient (≥0.6) to prevent slipping even in wet or oily environments. This makes it ideal for European and North American industrial walkways, stair treads, and offshore platforms 37.

✅ Versatile Design & Easy Installation

• Diverse Types & Customization: We offer various steel grating types, including welded steel grating, pressed steel grating, serrated steel grating, and fiberglass-reinforced plastic (FRP) steel grating. Customizable dimensions: width up to 1500mm, length up to 6000mm. Optional edge trims, end plates, and mounting clips for seamless integration with different project designs 58.
• Lightweight & Easy Installation: Compared to concrete plates, our steel grating is 60% lighter, reducing structural load and installation labor costs. Standardized sizes and pre-drilled holes allow for quick assembly using bolts or clips, shortening construction periods by 30% 69.

✅ All-Environment Adaptability & Longevity

• Corrosion & Wear Resistance: Advanced surface treatments (hot-dip galvanizing, passivation, painting) ensure excellent corrosion resistance. Hot-dip galvanized steel grating can withstand 5000+ hours of salt spray testing (ASTM B117), suitable for Southeast Asian coastal and Middle Eastern desert environments. High-hardness materials (HRC 45-55) resist wear from heavy traffic 58.
• Low Maintenance & Long Service Life: The open grid structure allows for easy drainage and ventilation, preventing water accumulation and rust. Service life ranges from 10-20 years (carbon steel) to 20-30 years (stainless steel) under normal use, with minimal maintenance required—only regular cleaning and inspection 79.

🏭 Advanced Manufacturing Process: The Foundation of Quality

1. Material Selection & Cutting: High-grade steel coils/sheets are selected based on customer requirements and inspected for chemical composition, mechanical properties, and surface defects. The steel is cut into bearing bars and cross bars of precise lengths using CNC cutting machines, with dimensional accuracy ±0.5mm 47.
2. Grating Forming: For welded steel grating, bearing bars and cross bars are positioned by computer-controlled jigs, then welded using high-frequency resistance welding (for carbon steel) or argon arc welding (for stainless steel) to ensure uniform welds and strong bonding. For pressed steel grating, the steel plate is pressed into a grid structure via hydraulic presses, ensuring high structural integrity 26.
3. Anti-Slip Processing (Optional): For serrated steel grating, the bearing bars are processed using CNC milling machines to form sharp serrations, enhancing anti-slip performance. The serration depth is controlled at 1-2mm to balance friction and walking comfort 38.
4. Edge Treatment & Trimming: The formed steel grating undergoes edge trimming to remove burrs and sharp edges. Optional edge trims (welded steel strips) are added to enhance edge strength and prevent injury during installation and use 59.
5. Surface Treatment: According to application needs, surface treatments such as hot-dip galvanizing, passivation, or powder coating are performed (detailed in the next section) 3.
6. Final Inspection & Packaging: Finished steel grating undergoes strict inspections, including load-bearing tests, weld strength tests, surface flatness checks, and corrosion resistance tests. Qualified products are packaged with moisture-proof films and wooden pallets to prevent damage during transportation, accompanied by complete test reports and installation manuals 9.

✨ Professional Surface Treatment: Enhance Durability & Aesthetics

1. Basic Surface Treatment

• Hot-Dip Galvanizing: The most widely used treatment for carbon steel grating. The grating is immersed in molten zinc (450℃) to form a uniform zinc layer (thickness 85-120μm), increasing corrosion resistance by 80%. Ideal for outdoor construction, industrial plants, and coastal projects in Southeast Asia and Africa 58.
• Electro-Galvanizing: A thinner zinc layer (10-20μm) is formed via electrolysis, providing basic corrosion resistance at a lower cost. Suitable for indoor applications such as warehouse platforms and light-duty walkways 7.
• Passivation Treatment: For stainless steel grating, nitric acid or citric acid solution forms a dense oxide film on the surface, enhancing corrosion resistance in acidic/alkaline environments. Widely used in North American and European chemical and pharmaceutical factories 39.
• Pickling Treatment: Removes oxide scale and oil stains from the steel surface, improving surface finish and enhancing the adhesion of subsequent coatings. Used as pre-treatment for painted or coated grating 6.

2. Optional Functional Coating Treatment

• Powder Coating: Available in various colors (RAL standard), the coating provides excellent corrosion resistance and aesthetics. Suitable for commercial buildings, decorative platforms, and indoor industrial areas in Europe and North America 8.
• Epoxy Coating: For highly corrosive environments such as chemical plants and wastewater treatment facilities, epoxy coating resists acids, alkalis, and organic solvents, extending service life by 2-3 times 7.
• Anti-Rust Paint Coating: A cost-effective option for indoor and mild outdoor environments, providing basic rust protection. Ideal for African and Asian industrial warehouses and workshops 5.
