COLORSTEEL Dridex® is a roof and wall cladding product with an anti-condensation fleece layer that collects, stores and then releases moisture. This layer, adhered to the reverse side of the COLORSTEEL® sheet, negates the need for separate underlay to be installed prior to the sheets being attached.
COLORSTEEL Dridex® is available in a range of profiles, please check with your local roll-former to confirm that COLORSTEEL Dridex® is available in your desired profile. Roll-forming companies operate throughout New Zealand, each offering their own range of profiles. Use our nation wide database to find the perfect supplier for your project.
COLORSTEEL DRIDEX® has been developed for residential and commercial buildings, industrial sheds, and farm buildings.

Can Dridex® be used on cladding?
Yes, Dridex® is suitable for both roofing & wall cladding. All accessories (such as gutters, flashings) are available from the regular COLORSTEEL® product range.
Can the absorbent backer be supplied on Zincalume®?
Dridex® is only available with pre-painted COLORSTEEL® products.
Does fungus grow on the Dridex® backer?
Dridex® pre-painted steel does not support fungal growth and is classified as a Class I material (a material that is extremely insensitive to fungus growth). It has been tested independently by TNO Bouw in the Netherlands.
Which colours is COLORSTEEL Dridex® available in?
Dridex® is available in all top coat colours. The Dridex® fleece colour is grey, similar to the Perpetual Grey® backer of COLORSTEEL®
How does a roofer become an accredited Dridex® Installer?
Only accredited roofers can install Dridex®. Face-to-face training is available from New Zealand Steel. Please contact your roll-former for more information on how to complete this qualification.
Why does Dridex® have to be stored dry prior to installation?
The backer of Dridex® is made to absorb water in wet environments. If the product is close stacked, the fleece backer has no room to breathe and the water will not evaporate. A wet stack of sheets can have an impact on the performance of the painted product. Furthermore, on the day of the installation, when the sheets are prepared and the drip edge is melted back from the edge, the melt back process will take much longer and time savings may not be achievable for the roofer.
Can I store Dridex® outside prior to installation?
No. You should not expose Dridex® to the outside weather conditions prior to installation. The product is designed to absorb water, so if it absorbs water while stacked the moisture can’t evaporate, causing the product to become significantly heavier. Furthermore, on the day of the installation, when the sheets are prepared and the drip edge is melted back from the edge, the melt back process will take much longer and time savings may not be achievable for the roofer.
Does Dridex® absorb water from gutters?
No. Capillary action on overhangs is managed by removing the backer 3-6cm from the sheet edge during installation.
