PurlinDek® is a cold rolled metal profile with a 6 metre load-bearing span capability, designed for use as a long span roofing. The strength of PurlinDek’s patented profile means less purlins, fixings and labour are required for the construction, resulting in time and cost savings.
With almost five decades in the New Zealand market, the PurlinDek® high rib profile is a proven performer for large commercial and industrial buildings. Where wide coverage and large spans is an essential part of the structure, PurlinDek® is ideal with it’s 6 metre load-bearing span capability.
The trapezoidal profile & shape provides incredible strength across long sections, and delivers greater water carrying capacity, and superior weather performance across a range of applications. It complies with current code requirements for loading without purlins or sub-framing. PurlinDek® also has outstanding eave overhang credentials. It can extend up to 1.8m, unsupported from the roof purlins in a 0.75g BMT.
Purlindek® is available in two gauges of iron;
This allows PurlinDek® to be an efficient profile with most commercial installations having less fixings and use 0.40g PurlinDek®. Weighing only 3.0kgs/m, a 20m sheet is easily handled by 3 roofers. With less Purlins needed and thinner iron gauge needed, the weight factor is reduced and with all steel products weight equals money.
A product of engineering research, PurlinDek® has a bold profile, shaped to eliminate capillary action of water and has positive interlocking of sheets to form a rigid structure. With PurlinDek® having a high profile allows sheets to be run up to 35m and expansion and contraction, hot and cold, there is no problem. PurlinDek® can also be laid at 3° pitch as the high profile takes the deluge without leaks. NZ Steel warrantees 3° pitch and greater.
