DB7

Steelformers DB7 is sleek, strong and stylish. It has a wider effective cover, high strength for wider purlin spacings and excellent water run off for low pitch roofs. Manufactured in our New Plymouth factory, it is one of the most stylish roofing and cladding profiles available, with its strong visual appeal and bold shaped profile. Being light and strong, Steelformers DB7 finds immediate acceptance in both domestic and commercial markets. Add value to your home with this great new profile.

A range of Alsynite Topglass (including Gelcoat Ultrasafe) equivalents are available and compatible with DB7, capable of being side and end lapped.

The NZMRM Code of Practice provides information on selection, fixing methods and patterns according to wind zones.
