Manhole cover product dimensions

Selection Instructions: 1. The flange plate flat steel is oriented in the load-bearing (supporting) direction, and the length L of the flat steel is determined based on the gap left for the trench (well) width.

2. Arrange by trench (well) length, using standard board widths of 995mm that match the processing modulus, with a gap of 5mm between boards.

3. The remaining part of the trench (well) less than 1 meter is sized by 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 sizes are available for customization.
