Carbon steel – perforated steel grating

Close Mesh Grating

1. Product Overview

Close Mesh Grating is a specially designed carbon steel grating featuring small, closely spaced openings that prevent small objects from falling through while maintaining excellent structural strength. This type of grating is engineered for applications where both pedestrian safety (high heel proof) and industrial load-bearing are required. Panels are precisely cut, welded, and treated to accommodate complex layouts, curved walkways, mezzanines, and platforms. Suitable for industrial facilities, urban infrastructure, commercial zones, and logistics environments requiring enhanced safety and load performance.

Engineering Notes:
Close mesh panels are engineered to prevent small objects, tools, or debris from falling through while offering strong structural performance. Bearing bar spacing below 25 mm is crucial for high heel/ball proof requirements, especially in pedestrian-heavy facilities. Hot-dip galvanizing ensures durability in corrosive and coastal environments. Customized shapes and cutouts can integrate with stair landings, curved walkways, and maintenance zones without compromising safety or performance.
