Product Description

Platform Stainless Steel Grating Pressure Welded Grating Plate

Galvanized grating, also called galvanized steel grating or galvanized steel bar grating, refers to steel bar grating made of mild carbon steel through hot dipped galvanized surface treatment.

Mild carbon steel provides an economical, high strength for use in most industrial and commercial applications. And hot dipped galvanized surface treatment supplies excellent corrosion resistance performance for durability.

Product Description

Structure: Welding with flat steel and cross/round bars with certain distances
Features: High strength, light structure, high bearing capacity
Surface: The hot dipped zinc coating gives the product excellent anti-corrosion properties

Steel Grating Types

1. Plain Type: One of the most widely used gratings, available for flooring, sidewalk, drainage pit cover, stair tread, etc

Plain type steel grating showing smooth surface design for flooring applications

2. Serrated Type: Better non-skid property & safety compared with plain grating

Serrated type steel grating with tooth-like surface for enhanced slip resistance

3. I-Shape Type: Lighter, more economical and practical comparing with plain grating

I-shape type steel grating with I-section bars for lightweight construction
