The HeliTie Bar is a Grade 304 austenitic stainless steel reinforcing material that has many unique properties. 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 extrusion process puts the fins into tension and the core into compression. The tensile strength of the base material is more than doubled during the manufacturing process. The deformation of the fins makes the bonding characteristics of the HeliTie Bar far superior to alternative standard reinforcing materials. Grade 316 steel is available for special requirements.
 

The uses for HeliTie Bar are both wide and varied and they can be utilised in new build and for many specialised refurbishment requirements.

In general terms the 6mm HeliTie Bar is used for the reinforcing of existing masonry structures, can be installed into existing masonry with very little disturbance to create beams which span over window or door openings or over soft areas of ground when footings have failed. It can also be used to create lintels. Crack stitching can be achieved by using 1M HeliTie bars.
