1. Walkways
It delivers a safe, stable walking surface for staff in industrial plants, factories, and warehouses. Its open-grid design not only ensures slip resistance but also lets dirt, liquids, and debris pass through easily—keeping the surface clean and free of hazards.
2. Steel Staircases
Perfect for industrial and commercial stair treads where durability and anti-slip performance are non-negotiable. For added safety, you can opt for serrated surfaces or anti-slip inserts.
3. Work Platforms
Widely applied in workshops and maintenance zones to support machinery, equipment, and workers. The open structure promotes proper ventilation and makes it simple to clean work surfaces.
4. Drainage Areas
The open-grid construction allows water, oils, and other fluids to flow through efficiently. It’s commonly installed in outdoor spaces, factory floors, and alongside drainage channels to ensure safe, effective fluid management.
Superior Weather & Corrosion Resistance: Options include hot-dip galvanizing, powder coating or industrial painting, suitable for indoor, outdoor and coastal/marine environments.
Safe, Non-Slip, and Well-Ventilated: Open-grid structure enables drainage and airflow, enhances slip resistance, and improves workplace safety.
Versatile Applications: Ideal for industrial, commercial and infrastructure projects (walkways, platforms, stairways, maintenance areas, drainage zones).
ISO 9001 Quality Assurance: Strict quality control ensures consistent performance across all batches.
Fast Delivery & Professional Support: Flexible production, packaging and logistics; standard delivery 7–15 days, with professional technical and customer support.
Packing
Standard Export Packing: Grating panels are securely bundled with steel straps to prevent deformation or damage during transit.
Customized Labels & Project Identification: Each bundle can be labeled with material grade, size specs and project codes for on-site efficiency.
Additional Protection: Wooden pallets, protective covers and enhanced packaging are available for sensitive surfaces or long-distance shipment.
Delivery
Lead Time: 7–15 days after order confirmation (varies by quantity and customization).
Flexible Shipping: Supports container loading, flatbed transport and local delivery.
Safe Handling: Packaging is designed for safe lifting, loading/unloading and easy on-site installation.
Stable cooperation with shipping companies such as MSK, MSC, COSCO efficiently logistics service chain, logistics service chain are we to your satisfaction.
We follow the standards of quality management system ISO9001 in all procedure, and have strict control from packaging material purchase to transport vehicle scheduling.
Q1: Materials of High Load Capacity Anti-Corrosion Galvanized Steel Grating
A1: Mainly high-quality structural carbon steel, welded then hot-dip galvanized (base steel for load-bearing, galvanizing for anti-corrosion).
Q2: Load-Bearing Capacity & Industrial Adaptability
A2: Load ranges from several hundred kg to tens of tons (varies by dimensions/spacing/thickness), meeting industrial heavy-duty needs.
Q3: Anti-Corrosion Effect & Service Life
A3: Hot-dip galvanizing forms a dense protective film; 15-20 years (indoor), 10-15 years (outdoor/coastal); additional treatments extend service life.
Q4: Customization Availability
A4: Supports customization of length (1-6m), width (500-1500mm), bar spacing (25-100mm), mesh size and surface treatment.
Q5: Slip Resistance & Applicability to Wet/Oily Environments
A5: Excellent slip resistance (open-grid + optional serrated/anti-slip inserts), suitable for wet, oily or snowy conditions.
