INNOVATIVE CLIP ELIMINATES NEED FOR A SUBSTRATE
Espan® has a unique clip system that allows for concealed fixings. The Espan® roofing simply locks onto the clip and allows for superior weather performance as it eliminates the need for fixing penetrations through the pan.
Another great benefit of the clip system is that Espan® has great spanning capabilities and eliminates the need for an often expensive substrate.
The clips are fixed directly onto the purlins at recommended spans depending on thickness and wind loadings.
The clip is manufactured from Zincalume® and comes standard with a 4mm coreflute pad that acts as a separator and cushion. The coreflute can be replaced if required.

THE COLORSTEEL® RANGE
All colours are available in COLORSTEEL® Maxam™. Please note colours below are indicative and we recommend you request a steel colour sample from your nearest Metalcraft Roofing branch. The homeowner should be aware that temperatures of dark colours are higher than those of lighter colours. Darker colours will thermally expand more. Thermal expansion of metal roofs is covered in the MRM Code of Practice. The MBIE document on roof cladding advises that noise from thermal expansion is normal and should be expected. Refer to MBIE -Guide to tolerances, materials and workmanship in new residential construction 2015.

OIL CANNING
Oil canning is an inherent characteristic of gauge cold formed metal products, particularly products with broad flat areas like Espan®. It is seen as waviness or distortion in the flat surfaces. Oil canning does not affect the products strength or performance . The architect, builder and homeowner needs to be aware that oil canning may affect the overall aesthetic outcome. Oil canning may occur during the roll-forming process and or during installation and where thermal expansion occurs. Please refer to MRM NZ Metal Roof and Wall Cladding Code Of Practice - Section 2.3.5 for more information. (www.metalroofing.org.nz). Refer also to MBIE -Guide to tolerances, materials and workmanship in new residential construction 2015 which advises oil canning is a common occurrence with products which have standing seams or wider profile patterns. This is not considered a defect and will become less apparent with weathering. The end result of the profile is dependent upon the quality of the timber substructure that supports it so it is critical that the roof purlins be square and level for optimum results.

FLEXIBILITY WITH DESIGN
Both Espan 340 and Espan 470 can be interlocked together allowing for greater design flexibility as demonstrated on Hornby Shopping Mall in Christchurch.
