Product Description

GEZHIGE No Dirt Accumulation Heavy Duty Steel Grating Manufacturing Stainless Steel Drain Grate China 1/2"X1/8" mm Bearing Bar 4mm Galvanized Steel Grating

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.

1. Description

(1) Structure: Welding with flat steel and cross/round bars with certain distances.

(2) Features: High strength, light structure, high bearing.

(3) Surface: The hot dipped zinc coating gives the product excellent anti-corrosion
