Permalite V-Rib®


PERMALITE V-RIB® is a roofing and walling profile that has a 915mm cover width and in conjunction with its symmetrical profile, provides a roofing sheet which can also be used effectively on walls. A double capillary drain in the rib overlap ensures almost total weather security. With a neat balanced appearance on buildings, this profile is also effectively used as insulation jacketing in power stations and chemical processing plants.

  • Fast fixing and minimum wastage due to the symmetry and large cover width.
  • Long lasting, durable, lightweight alternative to other cladding materials.
  • High relectivity and low emissivity values providing improved thermal performance.
  • Minimal maintenance to remain corrosion free.
  • The lighter mass of aluminium can provide a substantial reduction of the cost of transport to remote locations.
  • Can be used on walls.
  • Effectively used as insulation jacketing in power stations and chemical processing plants.


  • Galvanic corrosion may occur when aluminium, in the presence of water, is placed in contact with metals other than alloys of aluminium, non-magnetic stainless steel or zinc. Direct contact with zinc coated steel is not recommended in marine or industrial environments. See our Permalite® Aluminium Roofing Solutions Manual for more information.
  • If there are any doubts about the compatibility of other products being used, contact us.

All PERMALITE® aluminium roofing profiles are manufactured entirely from marine grade aluminium alloy 5251 or 5052 produced to AS/NZS 1734:1997.  Alloy 5251/5052 are high strength marine grade alloys with exceptional resistance to corrosion in marine or industrial environments.

The profiles are available in three finishes:

  • Mill Finish – an unpainted smooth lustrous finish which will dull relatively quickly and enhances corrosion resistance.
  • Standard Finish – stucco embossed mill finish, which reduces the specular reflectance of mill finish sheet.
  • Painted Finish – a range of quality painted finishes are available.

PERMALITE® Roof and Wall Sheet may be supplied pre-painted on one or both sides.

Aluminium provides a superior painting base for paint systems. Before roll forming, the paint is applied to the coiled sheet by reverse roller coating and heat curing on paint lines employing the latest painting technology.
