SSAB ERB 160 and SSAB ERB 160+
Download data sheet
The ERB 160 and 160+ are mostly used for tunneling and construction, but could also be used in the mines.
The tube thickness is 0.079". The bolts are delivered in bundles of 50 bolts per bundle. The bolts have a loading capacity of 35.97 kipf.
The ERB 160+ is made of special steel and has gone through a precise annealing process to give the bolts excellent elongation characteristics whilst maintaining good load bearing capacity. This gives the 160+ better capacity to follow rock deformation with squeezing ground or high strain concentration areas. The products are available within the length range of 94.488" - 236.220".
