Z-Bar

zbar

Z-Bar is a hot-rolled bar formed to give superior performance when used in conjunction with the latest resin bolting technology. The bar is designed in such a way that the nominal diameter of the bar approximates the pitch diameter of the thread, thus allowing for maximum thread strength, in relation to nominal bar diameter.

Lengths Studs and bolts are available in standard lengths from 0.6m to 3.0m in increments of 0.3m.
The length of the studs are measured overall, and bolts are measured from the end to under the forged head.
Non-standard lengths are available on request.

Duraset have a technologically advanced computerised tensile/compression testing facility, which we use for Research and Development as well as Quality Control. In addition to Research and Development and Quality Control tests, this facility is also capable of conducting short encapsulation and double embedment pull tests.

With ongoing investment in R&D in collaboration with our customers, Duraset is committed to continuously improve resin bolting technology resulting in better cost efficiencies.
Our multi-disciplinary R&D team work closely with research organisations and Universities to ensure ongoing innovation in resin bolting applications.
