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, using standard board widths of 995mm that conform to the processing module, with a gap of 5mm between boards.

3. The remaining part of the trench (well) over 1 meter is dimensioned by modular size.

4. Select the steel grating 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.
