Galvanized Steel Bar Grating combines high strength, light weight, and long-term corrosion resistance in a single hot-dip galvanized grid. Featuring a minimum zinc coating of 70μm, it delivers a 20–30 year maintenance-free service life-making it a standard choice for industrial platforms, walkways, stair treads, and trench covers.
Performance Advantages Of Galvanized Steel Bar Grating
Corrosion Resistance (Compliant with ISO 1461)
Hot-dip galvanized coating thickness ≥70μm; stable performance in pH 6–12.5 environments; offers a 20–30 year anti-corrosion lifespan, eliminating future maintenance costs.
Heavy-Duty Load Bearing (Double the capacity of cast iron gratings)
Made of Q235 carbon steel; flat bar specifications and spacing can be precisely calculated to meet specific needs. Load-bearing capacity is more than double that of traditional cast iron gratings of the same dimensions, capable of supporting heavy machinery traffic.
Ventilation and Light Transmission (Open area >80%)
Grid structure with an open area exceeding 80%, ensuring excellent airflow and natural lighting while facilitating rapid drainage-ideal for areas with poor lighting or a need for immediate heat dissipation.
R13-Rated Slip Resistance
Surface options include serrated or raised textures; achieves an R13 slip-resistance rating, effectively mitigating safety hazards caused by accumulated oil, water, or sloped walkways.
Main Classifications Of Galvanized Steel Bar Grating
1. Hot-dip galvanized grating: The metal grating is immersed in molten zinc to form a thicker zinc layer, offering superior corrosion resistance and making it suitable for outdoor or harsh environments.
2. Electro-galvanized grating: A zinc layer is deposited on the metal surface through electrolysis. This results in a thinner zinc layer and lower cost, but its corrosion resistance is weaker than hot-dip galvanizing.
Application Scenarios
Industrial Sector
Drainage Ditch Covers: Prevent large objects from falling while allowing water to flow through.
Construction Sector
As a decorative material for building facades, it combines aesthetics and ventilation. It can also be used for interior space partitioning, improving ventilation and lighting.
Transportation Sector
Bridges and Tunnels: Serving as maintenance platforms or ventilation structures, ensuring long-term corrosion resistance.
Rigorous Quality Control
System Certification: The company holds ISO9001:2015 quality management system certification, with the entire production process strictly adhering to standardized procedures.
Production Standards: Products are manufactured in strict accordance with the YB/T 4001.1-2019 standard and can meet international requirements such as American (ASTM), British (BS), and Australian (AS) standards.
Comprehensive Process Inspection: Quality control checkpoints are established at every stage-from raw material intake and welding to the final galvanized product. Finished products undergo critical testing for coating thickness (≥70μm), dimensional accuracy, and weld integrity to ensure every batch meets technical specifications; factory inspection reports are available upon request.
