Building Material Hot Dipped Galvanized Steel Grating For Trench Cover Or Foot Plate
Galvanized grating, also called galvanized steel grating or
galvanized steel bar grating, refers to the steel bar grating made
of mild carbon steel through hot dipped galvanized surface
treatment.
Mild carbon steel provides an economical, high strength for uses in
most industrial and commercial applications. And hot dipped
galvanized surface treatment supplies excellent corrosion
resistance performance for durability.
Steel grating is available in various material, such as stainless
steel, aluminum, and galvanized steel. Among them, the galvanized
steel grating is the most cost effective and economical type with
long service life and high load. And it is the most widely used in
both industrial, commercial and residential applications.
Hot-dip galvanizing is the most effective, economical and durable
process to protect steel from atmospheric corrosion. The process is
based on immersing the steel in a 450º molten zinc bath. The zinc
covers the steel and protects it from atmospheric oxidation
processes.
