The application of the SureTwist plus fixings are for securing counter battens over a layer of insulation, into the structural roofing timbers. Properties Fixing type: SureTwist plus. Length: 170mm. Profile: 6mm. Pack quantity: 100x fixings. Material: 304 grade austenitic stainless steel. Point: one point. Points Please note the SureTwist plus has one point and is used in the anchorage system. Bars without points are used in the reinforcement system. Bars with one or two points are used in the anchorage system, along with the two point dual diameter tie. We can supply the material in any length and profile to meet the requirements of structural engineers and other specifiers. Tension tested To Guarantee the products safety, tension is induced through the helical section by the twisting motion in the manufacturing process. Ensuring that impurities in the raw material aredetected, and any inferrior materials discarded. Technical data 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.
