Steel Grating

Steel Grating

1. Steel Grating Introduction

Steel grating is an open steel structure fixed by welding or press-locked, consisting of bearing flat steel and crossbars arranged at certain intervals in an orthogonal pattern; the crossbars are generally made of twisted square steel, but can also be round or flat steel, with materials available in 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.

Stainless steel commonly used 5mm

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

Flat Bar 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)

Example: The G253/30/100PG and above specifications utilize 25×3 plain flat steel, with a steel strip spacing of 30mm and a crossbar spacing of 100mm, for hot-dipped galvanized steel grating.

5. Application Scenarios

Primarily used for industrial platforms, boiler platforms, environmental protection equipment, ladder steps, guardrails, corridor flooring, railway bridge siderails, high-altitude tower platforms, drain covers, manhole covers, road grates, multi-level parking lots, and can also serve as exterior windows, balcony railings for residential buildings, guardrails for highways and railways, etc.
