SRG are the licensed Australian agent for the sale of Macalloy 1030 Post-Tensioning Bar. Macalloy bar systems are ideal for the economic application of post-tensioning forces on relatively short tendons. Through the use of threaded connections and anchorages they are simple to use and lend themselves to many applications.

The robust coarse thread (CT) provided to the Macalloy stressbars ensures rapid and reliable assembly, particularly suitable for onsite use and reuse. The Macalloy bar system consists of high tensile alloy steel bars in diameters of 25mm, 26.5mm, 32mm, 36mm, 40mm, 50mm and 75mm provided with cold rolled threads for part or full length, together with a range of fittings. Bars from 25mm to 50mm diameter obtain their specified properties via a quenched and tempered process. Stainless steel Macalloy S1030 bars in diameters from 20mm to 40mm are made from precipitation hardened stainless steel.
