Grating product dimensions

Selecting Instructions: 1. The flat steel direction of the manhole cover is the load-bearing (support) direction, and the length of the flat steel L is determined by leaving a gap 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) 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 specifications are available for customization.
