Steel Grate Introduction
Steel Grate is a metal grid structure made of carbon steel or stainless steel, which is widely used in industrial platforms, walkways, drainage systems, stair treads and other fields. It is usually made of load-bearing flat steel and crossbars welded or pressed together, and has the advantages of high strength, anti-slip, corrosion resistance, water permeability and breathability.
Specification
🔹 Common specifications (examples)
Type Flat steel size (mm) Spacing (mm) Crossbar spacing (mm) Surface treatment
Ordinary welded steel grating 25x3 / 30x3 30 / 40 100 / 50 Hot-dip galvanized / spray-painted
Toothed steel grating 25x5 / 32x5 30 / 40 100 / 50 Hot-dip galvanized / stainless steel
Heavy-duty steel grating 40x5 / 50x5 30 / 40 100 / 50 Hot-dip galvanized
⚠ Note: Different specifications, materials and surface treatments can be customized according to needs.
🔹 Common types
1️⃣ Welded Steel Grating
The load-bearing flat steel and crossbar are connected by electric welding, with a strong structure, suitable for industrial platforms, ground drainage, etc.
2️⃣ Press-Locked Grating
The flat steel and crossbar are tightly combined by mechanical pressing, suitable for decoration, commercial buildings, etc.
3️⃣ Serrated Steel Grating
The flat steel surface has serrated shape to improve the anti-slip performance, suitable for humid or oily environments, such as oil fields, docks, etc.
4️⃣ Heavy-Duty Grating
It uses thickened flat steel with stronger load-bearing capacity, suitable for airports, freight docks, large equipment channels, etc.
Feature
🔹 Main features
✅ High load-bearing capacity: It can withstand heavy loads and is suitable for industrial sites and pedestrian walkways.
✅ Anti-slip safety: The surface can be treated with anti-slip treatment to enhance friction and reduce the risk of slipping.
✅ Strong corrosion resistance: Galvanized, stainless steel and other materials can be selected to improve durability and adapt to different environments.
✅ Water permeable and breathable: The open structure is convenient for drainage and ventilation, and reduces water accumulation problems.
✅ Easy to install and maintain: The structure is simple, easy to install, and the long-term use cost is low.
