Hot DIP Galvanized Steel Grating with 25x5mm Bearing Bar and Serrated Style for Industrial Walkways
Galvanized grating consists of metal grates that undergo a specialized zinc coating process called galvanization. This treatment creates a protective barrier that significantly enhances the material's resistance to rust and corrosion. GNEE Steel provides premium grating manufactured from high-strength steel, offering superior structural integrity while withstanding harsh environmental conditions.
Hot DIP galvanized metal grating has three kinds of steel gratings: Plain Style Steel Grating, Serrated Style Steel Grating and I Bar Type Steel Grating. They are widely used in steel structure platforms, stair treads, sidewalks, drainages and well covers. We can design and manufacture standard steel grating and customized shapes per client's requirements.
