Trench Covers |

|
|
Construction |
Materials & Finishes |
Trench covers are made from Rectagrid RS40 type grating with a bearer bar and transverse bar pitch of 40mm. They are banded along the span only. |
|
Note |
O.E.S. grating in narrow panels like trench covers, is not recommended where grating has to carry heavy wheeled traffic. Banding is welded on to the bearer bars in these cases to prevent the grating from curling up when heavy loads are applied.
These trench covers can be easily removed when trenches require cleaning. All trench covers are 1000mm wide and any trench length can be covered by using several individual gratings. |
