Dimond Roofing Showpiece Case Study

Arrow International has recently completed a new building for leading New Zealand manufacturer EPL Group. The building, designed by Cymon Allfrey Architects, is a fantastic showpiece portraying how an industrial premise can be transformed from something that is  often plain into something truly stunning and unique.

The office block attached to the main warehouse has been installed with Dimond® Roofing Eurotray® on both  the  roof and walls.. However that’s just the start – it’s the unique flashing details and roof lines combined with a huge curve and twist that extends the length of the roof that make this project so distinctive.

Eurotray® Roll Cap by Dimond® Roofing was chosen because of the widely spaced ribs which offer a subtle texture to the exterior of the building. From a technical perspective, it provided the 3-4mm of tolerance between the sheets that was required to achieve the twist in the roof. The roof visually appears to curve but it is better described as a twist. Each rib is a perfectly straight line but they are positioned on a slightly different angle to the rib before, giving the curved appearance. The architects gave the contractor set out points for the end of each rib, then using the magic of trigonometry and CAD modelling, they managed to make it work.

All design is a collaborative effort. A robust discussion was had prior to commencement to be sure the end result was exactly as envisaged by Dimond® and the client. When designing something outside of the “normal” way of doing it, you need to take the time and advice from fabricators and installers to ensure that it is done correctly. TM Consultants, who were the structural engineers, also played a fundamental role in achieving the end result.

A New Zealand inspired design and the most popular profile of the Eurotray® family, Eurotray® Roll Cap offers clean lines and a uniquely robust and distinctive look. Visualise the traditional timber board and batten look and then imagine this in metal and you have Roll Cap. The profile is ideally suited to withstand New Zealand’s harshest climates and is compatible with Photo-Voltaic Laminate (PVL) to allow solar energy generation. Additionally, Eurotray® has the option to be manufactured on site, a critical advantage on some jobs when sheets are too long for transportation.
