Cattle Grids

Cattle grids look deceptively simple to build. Anyone who has tried to specify one knows differently. Blackburn & Roberts Ltd have developed a modular range of cattle grids to suit every location. All units are made from steel to BS 4360 and hot dip galvanised to BS 729.

Our cattle grid designs are animal friendly. Rails are in profiles which minimise injury to stock which tangle with the unit. Escape routes are provided for hedgehogs and other small animals which fall into it. Cattle Grids are used in a wide variety of locations. We have units appropriate to every location whether Domestic, Highway, Off Highway or Heavy Industrial.


Cycleway Cattle Grids

Cycling is continuing to grow and is attracting a wider range of people. Cycleways that cross fields create corridors for animals which creates problems and leads to fouled trackways and irate farmers. As the Cattle Grid supplier with the widest range of models we felt obliged to deal with this issue. Our units use as many of the recommendations of BS 4008:2006 as practical in our design. The units are designed to carry a Live Load of 5Kn/sq m to comply with DoT Pedestrian and Cyclist specification. The units are fabricated from Mild Steel and are hot dip galvanised for maximum life.

Domestic Cattle Grids

It is important to remember that large vehicles need to be able to access most homes, occasionally, to make deliveries or for house moves. Provision needs to be made for these occasions when selecting the most suitable grid type. Domestic Cattle grids consist of a steel tubular section fabricated grid which is supported at the ends and at intervals across the pit on sleeper walls. A bearing strip coincides with the top of the sleeper wall. This ensures efficient load transfer and provides hold down fixing points. We provide a drawing showing the position of the walls with every order for Domestic Grids. The tubes are usual circular in section but we occasionally use rectangular section when refurbishing an existing grid with levels and loads defined by the in-place pit. It is usual to provide chamfers on the edges of the sleeper walls to deter animals from trying to cross on the top of the walls.

Off Highway Cattle Grids

off-highway-cattle-grids

For the installation of our off highway cattle grids, a pit is excavated and drainage installed. An appropriate quantity of ballast is then placed into the pit and compacted level. The cattle grid unit is lifted off the delivery vehicle and placed in position. The void round it is back filled. The unit can be dismantled to reduce the weight and permit the use of smaller excavators. Once the grid is in position it can be used immediately. Excellent edge finishing can be achieved if the track is surfaced. The unit can be dismantled to reduce the weight and permit the use of smaller excavators. Once the grid is in position it can be used immediately.
