Product Description

Heavy Duty Anti-Slip Serrated Steel Deck Grating

Steel grating is manufactured through a precision welding process that combines bearing bars and cross bars arranged in a flat-steel weft pattern. The production involves high-pressure resistance welding followed by cutting, notching, opening, and overlocking processes to create finished products that meet specific customer requirements.

Our steel gratings feature exceptional strength-to-weight ratio, lightweight construction, superior load-bearing capacity, and easy installation. The hot-dip galvanized coating provides outstanding corrosion resistance for long-lasting performance.

Product Advantages

Hot-dip galvanized steel grating offers exceptional cost-effectiveness and is widely used in construction projects for paved drainage systems on both new and existing roadbeds. The specialized hot-dip galvanizing treatment creates stable chemical and physical properties that resist corrosion and oxidation from environmental exposure and microorganisms, significantly enhancing trench load capacity.

Surface Treatment Processes

Stainless Steel Finishing Options

Pickling Passivation: Immersing the stainless steel grating in specialized solution to achieve a uniform silver-white matte surface finish
Electrolytic Polishing: Processing in heated electrolytic solution at 75°C for 1-3 minutes to produce a bright, polished stainless steel surface
