Patented Macalloy thread allows low lock-off losses during stressing
Macalloy was the first company in the world to develop a post-tensioning bar system in the 1940s. The product has since evolved to include a unique fatigue-resistant thread form that provides low lock-off losses on stressing.
The Macalloy 1030 and S1030 post-tensioning bar systems are high strength with superior fatigue properties. The Macalloy Post Tension bar provides an ultimate yield strength of 1030 N/mm2.
The Macalloy Post Tension bar is available in diameters from 25 to 75mm and lengths of up to 11.8m. Longer lengths can be achieved by joining bars together with couplers. Custom sizes are available on request.
The 1030 bar is a carbon chrome steel bar with high strength properties achieved by cold working or heat treatment.
The stainless-steel version (S1030) is a martensitic nickel-chrome alloy steel, hardened during the manufacturing process. Available in diameters 20 to 75mm and lengths of 6m. Longer lengths can be achieved by joining bars together with couplers. Custom sizes are available on request.
A range of accessories including nuts, washers, end plates and ducts can also be supplied.
