Firstly, the selection of the rear cover is crucial. Choosing the appropriate rear cover based on business needs can ensure the quality of the drainage trench and control costs. What should be considered when selecting a rear cover?
For pedestrian crossings, vehicle lanes, zinc-coated grating panels in underground parking lots, and trench covers for ports or building structures, design and model selection should be considered due to their varying load-bearing capacities and vehicle orientations.
When used on road drainage ditches and cross-section manholes (with the direction of the luxury car assembly parallel to the load-bearing galvanized flat steel), it is not only important to understand wheel load and impact but also to avoid the danger of the manhole cover jumping. The manhole cover must be secured with angle iron and support beams (either by welding or using steel grating installation clips).
3. Load-bearing capacity adopted: Lightweight - 25 tons/m², suitable for trolleys, campus residential parks, ecological parks, underground parking garages, kitchens, etc.
