Heras Fence Blocks

rotoblock site safety barriers with mesh panels

The Heras fences are very popular in the UK as perimeter fencing around construction sites and we now offer a water filled block that can be used for the Heras fences and a wide range of other fence panels.

Unlike the original Heras feet these are easily visible in Red and White and each block can take a maximum of 105 kg.

Mira Tested wind speeds on a 3.5 metre Heras panel in the following configurations giving stability at up to 73 mph winds.
