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
