High-Strength Serrated Stainless Steel Grating for Stairs & Drainage
What Is Steel Grating?

Steel grating is manufactured from high-quality carbon steel or stainless steel. Flat steel bars are arranged crosswise at specific intervals and welded into a grid pattern with square openings. The exterior of steel grating is typically hot-dip galvanized to provide corrosion resistance.

Steel grating offers excellent ventilation, light transmission, anti-slip properties, strong load-bearing capacity, heat dissipation, easy cleaning, and simple installation.

Frequently Asked Questions
How long does galvanized steel grating last?
Typically 15-30 years depending on environment and maintenance.
Is steel grating fire-resistant?
Yes, steel grating is non-combustible and suitable for high-temperature applications.
What is the standard size of steel grating panels?
Standard panels are 1m x 6m or 1.2m x 6m, but custom sizes are common.
How thick is steel grating?
Thickness varies from 25mm to 50mm or more, depending on load requirements.
What are bearing bars and cross bars?
Bearing bars carry the load; cross bars hold the bearing bars in place.
Can steel grating support heavy machinery?
Yes, with proper design, steel grating can support industrial equipment.
How is steel grating installed?
It can be mounted on support frames, welded, bolted, or anchored depending on the structure.
