COLORSTEEL DRIDEX is a roof and wall cladding product with an anti-condensation fleece layer adhered to the reverse side. This layer negates the need for separate underlay to be installed prior to the sheets being attached.
Reduces installation time
Installation is less affected by wind, reducing down time
Available on all trapezoidal and corrugate profiles
Can be used for roof and wall cladding on most building types — including residential buildings, industrial sheds, and a range of farm buildings
COLORSTEEL Endura Dridex is suitable for mild to moderate environments
COLORSTEEL Maxx Dridex can be used in severe marine environments
