Product Description
Galvanized Steel Grating Overview

Galvanized steel grating features mild carbon steel construction with hot-dipped galvanized surface treatment for superior corrosion protection. These structural elements provide exceptional strength and durability for industrial applications.

Custom galvanized steel bar grating for trench drain covers and industrial walkways

Gratings serve as effective filters over drains and air vents, blocking large solids while allowing liquid and air movement. The heavy zinc coating ensures long-term performance in demanding environments.
