Steel Grating

Steel Grating

1. Steel Grating Introduction

Steel grating panels are open steel structures composed of bearing flat steel and cross bars arranged at a certain spacing in orthogonal fashion, fixed by welding or press lock. The cross bars are usually made of twisted square steel, round steel, or flat steel, and the materials are divided into 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-sized steel grating utilizes 5mm twisted square steel.

Common stainless steel thickness: 5mm

Flat steel sizes: Commonly available in various specifications from 20×3mm to 75×6mm

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: The specifications above G253/30/100PG utilize 25×3 flat steel bars, with a spacing of 30mm between the bars and 100mm between the crossbars, forming hot-dipped galvanized steel grating.
