Product Description
Product Overview
Hot-dipped galvanized steel grating manufactured from mild carbon steel with heavy zinc coating protection. This heavy-duty structural element provides superior corrosion resistance and durability for industrial applications.
Applications & Uses
Galvanized steel grating serves as strong, durable bearing structural elements in offshore oil rig platforms, refineries, walkways, and various industrial settings. It functions as filters for drains and air vents, blocking large solids while allowing liquid movement.
