The plug-in welded design sets this ditch cover grating apart from traditional welded gratings, as individual panels can be easily lifted and removed for maintenance, reducing downtime for sewer line cleaning or pipe repairs. The hot-dip galvanized coating protects against rust and corrosion in outdoor or buried environments, outperforming paint-coated covers in harsh weather conditions. The standardized mesh opening size prevents large debris such as leaves, trash, and small stones from entering drainage systems, reducing the frequency of clogged pipes. The lightweight yet strong structure minimizes stress on underground drainage frames, while the flat surface provides a safe, non-slip walking surface for pedestrians and light vehicles such as golf carts or maintenance trucks.
The standard panel dimensions are 3000mm in length and 600mm in width, with custom sizes available to fit specific ditch widths. The bearing bars have a width of 45mm and thickness of 4mm, while cross bars are made of 6mm diameter round steel with a spacing of 60mm. The mesh opening size is 50mm x 100mm, which balances drainage efficiency and debris blocking performance. The load rating is Class B per EN 124, supporting up to 10kN/m of dynamic load. The weight per square meter is 26.3kg, and it complies with EN 124 and ISO 9001 quality and safety standards.
This plug-in welded steel grating ditch cover is ideal for municipal road drainage trenches, parking lot storm drains, industrial plant drainage channels, sidewalk trench covers, and pedestrian bridge drainage systems. It is suitable for both urban public spaces and industrial facilities, providing reliable drainage and easy maintenance access for underground utility systems.
