Hurricane Rib™

Features

Developed as an economical profile for use in known cyclonic zones. High level of rigidity and good structural performance. 1.5 corrugation sidelap.

Applications

May be specified as single skin, thermally or acoustically rated roof and/or wall cladding.

Applications have included structures for defence and aviation in cyclonic regions.

Orientation & Accessories

Can be installed as a vertical, horizontal or diagonal system to walls. Supplied with a range of accessories as required.
