Grate product dimensions

Selection Instructions: 1. The flat steel on the manhole cover is oriented in the load-bearing (support) direction; the length of the flat steel L is determined based on the width of the trench (well) and the gap left.

2. Arrange by trench (well) length, selecting a standard board width of 995mm that conforms to the processing modulus, 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 panel model based on the trench width and load-bearing requirements.

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