Grating 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, with a 5mm gap between boards.

3. The remaining part of the trench (well) that is less than 1 meter in length is sized by modular dimensions.

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

5. We recommend designing and constructing with standard size manhole covers; other sizes are available for customization.
