Guide To Choosing The Right Steel Grating Trench Cover

Time:2022-03-22

Selecting the right steel grating trench cover depends on three main factors:

Load Rating:

Pedestrian Area (A15/B125): For sidewalks, parks, and gardens. (e.g., G253/30/100)

Car Parks / Driveways (C250/D400): For light vehicles and residential areas. (e.g., G325/30/100)

Industrial / Heavy Duty (D400/E600): For forklifts, trucks, and ports. (e.g., G505/30/100 or Heavy Duty Grating)

Material:

Carbon Steel (HDG): Most common, cost-effective, anti-corrosion via Hot-Dip Galvanizing.

Stainless Steel (304/316): For food processing, pharmaceuticals, and coastal areas (corrosion-resistant).

Ductile Iron: For heavy traffic roads and airports.

Slot Design:

Open Mesh: Standard bar grating, good for water flow but allows debris.

Linear Slot (Heel-Proof): Narrow slots (<15mm) to prevent high heels from getting stuck, ideal for public areas.
