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
