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 crossbars at a certain spacing in an orthogonal arrangement; the crossbars are generally made of twisted square steel, round steel, or flat steel, and are available in carbon steel and stainless steel materials.

3. Steel Grating Model Explanation
Material Type: G for Carbon Steel
BG - Stainless Steel
Rod 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
Flange Steel Sizes: Standard sizes ranging from 20×3mm to 75×6mm and more
Flange Spacing: Series 1 - 30mm (center to center)
Series 2 - 40mm (Center Distance)
Series 3, 60mm (Center Distance)
Flat Steel Type: P for Plain Flat 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)
Example: G253/30/100PG specifications use 25×3 standard flat steel strips, with a strip spacing of 30mm and a cross-bar spacing of 100mm, forming hot-dip galvanized steel grating.
