Steel Grating
1. Steel Grating Introduction
Steel grating is an open steel structure fixed by welding or press locking, composed of bearing flat steel and cross bars at a certain spacing in an orthogonal arrangement; the cross bars are usually made of twisted square steel, but can also be round or flat steel. The materials are carbon steel and stainless steel.

3. Steel Grating Model Explanation
Material Type: G for Carbon Steel
BG for stainless steel
Bar Spacing: 100mm (Center to Center)
50mm (center distance)
Bar Size: Standard 6mm Twisted Square Steel
Small-scale steel grating is made of 5mm twisted square steel.
Common stainless steel thickness: 5mm
Flat Steel Dimensions: Standard sizes range from 20×3mm to 75×6mm and various specifications
Flat Steel Spacing: Series 1 - 30mm (Center to Center)
Series 2 - 40mm (Center Distance)
Series 3 - 60mm (Center Distance)
Flat Steel Type: P for Plain Surface Type (can be abbreviated)
S for enhanced anti-slip tooth pattern
Surface Treatment: G for Hot-Dip Galvanized
U for surface untreated (can be abbreviated)
For example, G253/30/100PG and above specifications use 25×3 standard flat steel strips, with strip spacing of 30mm and crossbar spacing of 100mm, to form hot-dip galvanized steel grating.
