Helical Bars

The SureTwist Helical Anchorage System is offering you an optimum solution. SureTwist is an austenitic stainless steel, Grade 1.4301 or 1.4401 - DIN EN 10088 Part 3 (1995), AISI - 304 or 316, reinforcing material that has many unique properties (Or 8.8 High Tensile Steel for specific applications). Being rolled from a plain round wire, the fins are work-hardened to a very high level whilst the core remains relatively soft. The subsequent twisting process puts the fins into tension and the core into compression. The tension induced by the twisting process also ensures that any impurities in the base material are detected early, helping to produce a safer product. The tensile strength of the base material is more than doubled during the manufacturing process. The pronounced fins over the core make the bonding characteristics of the SureTwist Profile far superior to alternative standard reinforcing materials.
