Galvanized Walkway Grating is a load-bearing metal panel with regularly arranged openings that allow water, air, light, and small debris to pass through the surface. It uses Q235 steel, 32 mm-high and 5 mm-thick bearing bars, and a 100 mm grid length. A hot-dip galvanized finish provides corrosion protection for outdoor, humid, and industrial locations. The open structure helps prevent standing water and reduces the amount of material retained on the walking surface. It provides a practical flooring solution where load support, drainage, ventilation, straightforward installation, and routine maintenance are required within the same structure.

Main Applications
The galvanized walkway grating is suitable for industrial operating platforms and maintenance walkways.
Power plants, chemical facilities, and manufacturing workshops.
Drainage channels, service trenches, and equipment access areas.
Elevated floors around pipelines, tanks, and processing machinery.
Installation and Maintenance
Panels should be supported in the specified bearing-bar direction and fixed to prevent movement during use. Installation drawings need to identify panel dimensions, supporting spans, openings, edge bars, and removable sections. Galvanized surfaces should be checked after cutting or on-site modification, particularly around exposed edges. The open grid allows visual inspection of the supporting structure and simplifies cleaning because water and loose material can pass through the openings.
FAQ
Q: Which standard applies to galvanized walkway grating?
