Dimond V-Rib Profile

The clean-cut, striking appearance of V-Rib makes it a very popular roofing and cladding profile used on a wide range of applications from the Comalco Aluminium Smelter at Tiwai Point, Southland to the prestigious Mikano restaurant on Auckland’s waterfront. The symmetrical sections have inherent strength characteristics which provide a good tolerance to foot traffic as well as the title of the strongest drape curved roofing profile available. Where design criteria demands continuous length, economy and simple, speedy construction choose V-Rib.
