by pwdale25 — last modified Wed, 24 Jul 2013

The Macalloy 1030 is a carbon chrome steel with a composition designed to give the specified properties. The Macalloy 1030 Post Tensioning System consists of high tensile alloy steel bars. Download our brochures below for more information. Alternatively you can contact us; the details can be found at the bottom of this page.

The Macalloy 1030 and S1030 post tensioning bar systems are high strength bar systems with superior fatigue properties. The Macalloy Post Tension bar provides an ultimate yield strength of 1030 N/mm2.

Macalloy was the first company in the world to develop a post tensioning bar system in the 1940’s and the product has evolved to include a unique fatigue resistant thread form that provides low lock off losses on stressing.

The Macalloy 1030 is a carbon-chrome steel with a composition designed to give specified properties.

The Macalloy Post Tension bar is available in diameters from 20 to 75mm.

Post Tensioning Bar

The 1030 bar is a high strength carbon chrome steel bar with the high strength properties achieved by either cold working or heat treatment. A Stainless Steel version is available, The Macalloy S1030, which is a martensitic nickel-chrome alloy steel, hardened during the manufacturing process.

Bars are available in standard lengths up to 11.8 metres and longer lengths can be achieved by joining bars together with couplers. A range of accessories including nuts, washers, end plates and ducts are also available.

For corrosion protection, in addition to standard ducts, Macalloy can also supply bars with factory applied Denso Tape. Denso tape is a grease impregnated tape with technical and cost saving benefits over traditional duct and grout solutions.

Macalloy PT bars up to 50mm diameter carry the European CE marking and are approved to the requirements of ETAG 13.

Macalloy can provide technical and onsite support. See separate pages for more information.
