Grate product dimensions

Selection Instructions: 1. The flat steel direction of the manhole cover is the load-bearing (supporting) direction; determine the length L of the flat steel based on the gap left according to the width of the trench (well).

2. Arrange by trench (well) length, selecting a standard board width of 995mm that conforms to the processing module, with a gap of 5mm between boards.

3. The remaining part of the trench (or well) less than 1 meter is sized based on modular dimensions.

4. Select the steel grating model based on the trench (well) width and load-bearing requirements.

5. We recommend using standard size manhole covers for design and construction; other specifications are available for customization.
