Trench Cover Steel Grating

Steel grating for drainage channels is a metal product formed by cross-welding flat bars and crossbars. Primarily used as drainage channel covers, platform decking, and stair treads, it features high strength, corrosion resistance, and easy maintenance.

Materials and Processes

Carbon Steel/Stainless Steel: Common materials include Q235B carbon steel (hot-dip galvanized) and 304/316L stainless steel. Hot-dip galvanized gratings feature a zinc coating ≥85μm for enhanced weather resistance.

Surface Treatment: Primarily employs hot-dip galvanizing for outstanding corrosion and rust prevention, with service life reaching 5 years (outdoor municipal applications) or over 10 years (stainless steel variants).

Product Features

Superior Drainage: Offers twice the drainage area of cast iron grates, minimizing water accumulation risks.

Load-Bearing & Wear Resistance: Supports pedestrian traffic and small equipment passage while resisting deformation and wear during prolonged use.

Easy Installation: Supports custom standard sizes with pre-production sample verification, achieving a 99.5% direct installation rate.

Applications

Ideal for municipal roads, industrial parks, docks, airports, and other environments requiring large spans, high load-bearing capacity, and strict drainage standards. Replaces traditional cement or cast iron grates to reduce maintenance costs.
