Long Run
ROOFING & WALL CLADDING
Steel roofing has been installed in NewZealand since the Pākehā brought kitset houses from Europe in the 1800s. It has been a tried and tested solution and regarded as the roof of choice by many New Zealanders.
Early roofing involved using 3.0 metre sheets and lapping them to cover longer roof planes. Modern manufacturing techniques have allowed us to use full length sheets without laps. The range of profiles has also increased with a range of manufacturers offering unique designs.
Roofing sheets vary in thickness, but typically most residential roofing is 0.4mm (base metal thickness) and commercial is 0.55 BMT to cope with the bigger spans. Please refer to the specific manufacturers product information sheets for further information regarding the technical performance of their products.
Corrugated
Corrugated roofing has become a timeless choice for many, being used on everyday housing through to high end projects. It suits roof pitches steeper than 8 degrees. Often laid on purlins at 900mm centres for standard installation. This may vary subject to the manufacturer’s technical information.
5 Rib and 6 Rib
These products are popular local choices especially for lower pitched roofs as they can be laid from 4 degrees upwards. They can span further than subject to the manufacturer’s technical information.
V Rib
V Rib is an angular profile with pans equal to the rib and is often used on architectural homes and commercial builds. V Rib can be from 4 degrees and is wider than the generic 5 and 6 rib profiles.
Commercial Profiles
There are a plethora of products on the market for commercial/industrial applications, such as Solar Rib and DP955. Commercial Profiles can generally be laid to wider purlin spans than residential profiles, reducing overall build costs and speeding up installation. We have access to a wide range of profiles and can assist with the selection of suitable products for your build.
