Overview
I Bar Grating is manufactured via pressure welding, forming an open-grid structure with I-shaped bearing bars and cross rods. This Grating provides controlled deflection within 1/200 of span length under rated load, supporting heavy-duty industrial applications without structural deformation.

Product Advantages
- Bending strength: I-shaped section increases moment of inertia, enabling 5 tons/m² static load capacity.
- Deflection limited to ≤1/200 of span under full load, verified by structural calculation.
- Serrated design improves friction coefficient, suitable for oily or wet environments.
- Hot-dip galvanizing ≥85 μm passes 1000-hour salt spray test without corrosion.
Applications
- Industrial platforms (chemical plants, power plants) – load ≥5 kN/m²
- Municipal engineering – drainage covers, stair treads with front edge cladding
- Special environments: mines (bar spacing 60 mm to prevent falling objects), coastal areas (zinc coating ≥100 μm)
