Hot-Dipped Galvanized Steel Grating for Industrial Catwalk & Flooring
Steel bar grating with high strength and firm structure is made from carbon steel, aluminum steel, or stainless steel. Available in various manufacturing methods including welded, press-locked, swage-locked, and riveted gratings, with surface options of smooth or serrated patterns. These versatile gratings are widely used in stair treads, walkways, platforms, floors, covers, wheeled equipment, security screens, and heavy-duty construction applications.
Surface Treatment Options
We provide four finishes for anti-corrosion treatment of carbon steel bar grating:
Black / Bare Steel: No finish, shortest lifespan, most economical option
Painted Coat: General anti-rust protection, available in various colors
Electro-galvanized: Light zinc coating, may experience minor corrosion in humid environments
Hot-dip galvanized: Most commonly used method providing superior anti-rust protection, compliant with ASTM A123 or GB/T 13912-2002 standards
