MS Tophat Purlin and Girt

Metalcraft Roofing's structural division manufactures MS Tophats for the New Zealand construction market, in particular the pre-engineered sheds and garage market segment. MS Tophats are cut to length and available in a range of sizes and gauges to suit a variety of applications.

Some description

The MS Tophats are manufactured from high tensile Z275 galvanised coil in accordance with AS1397. MS Tophats can be used as roof purlins, wall girts and floor joists and are an economical alternative to timber and ‘C’ section purlins for spans up to 7 metres.

MS Tophats are easy to use and fasten directly to their supports which eliminates the requirements for cleats. As MS Tophats are symmetrical there is no requirement for braces or nogs to prevent twisting. This allows the MS Tophats to be easily lapped for maximum performance. Thermal breaks are required between the MS Tophat and cladding to avoid thermal bridging and contact with materials not compatible with Zinc should be avoided.
