Precision engineered reinforcing steels used for retrofit bed joint rein­for­cem­ent to upgrade the tensile and flexural capacity of a masonry wall. The bars have deep and continuous helical troughs that ensure bonding cha­rac­te­ris­tics with proprietary mortars are superior to those of any alternative brick re­in­for­cement bar.

The twisted bars are manuf­ac­tu­red from round stainless steel wire, which is passed through a series of profiled rolls to prog­res­sive­ly alter its shape in cross-section. The cold rolled shaped wire is then forced through a twisting die to deliver a patented precision engineered helical re­in­for­cem­ent bar with unique torsional elastic yield cha­racteristics and a tensile strength that is double that of standard stainless steel.

Why do these shaped and twisted helical bars offer superior re­in­for­cem­ent to earler versions of helibar?

• Upgraded by the inventor and designer of the earlier Helifix helibar product
• Raw material is selected from a single grade of stainless steel within the 304 range for greater consistency
• Re-designed cross sectional shape for improved strength and to alleviate inter-annealing processes
• Die operated twisting technique for unequalled consistency of pitch angle and tensile strength

Twistfix Helical bars provide a quick, easy and cost-effective means of restoring or adding strength to existing buildings.
