HEA Panel
When large, possibly unstable rocks cannot be safely removed from the rock face, a system is required that actively secures or 'straps' that rock back into the rock face stopping it from detaching and falling.
Traditionally a series of rock bolts or anchors would be installed around the loose rock and steel cables would be laced across the outcrop between the anchors.
Now Maccaferri HEA panels can be used instead and offer reassuring and reliable strength in a rapid and simple method to install ready-made panel configuration. These consist of single high tensile steel cable (1770 N/mm) woven into a panel of square grids.
Where the cable moves over itself to form the grid, the inter-sector is secured with our patented 'knot' system. This connection is far stronger than the traditional 'clip' connection, thus offering improved performance and reliability especially in demanding applications.
By offering a variety of steel cable diameters, and grid apertures, Maccaferri HEA panels can suit most applications. The size of the panels can be manufactured to suit your application up to a maximum size of 10x6m.
