PERMALITE V-RIB™
Product Description and Features
PERMALITE V-RIB™ is a roofing and walling profile made from marine grade aluminium alloy. It has a 915mm cover width and a symmetrical profile. A double capillary drain in the rib overlap ensures weather security.
- Fast fixing and minimum wastage due to the symmetry and large cover width.
- Long lasting, durable, lightweight alternative to other cladding materials.
- High thermal insulation. This is significant in reducing the operating cost of air conditioning.
- Minimal maintenance to remain corrosion free.
- The lighter mass of aluminium can provide a substantial reduction of the cost of transport to remote locations.
Produced to: AS1734
Common Uses of this product
Small projects and complex roof and walls or where a striking design is required. As well as providing a neat, balanced appearance on buildings, this profile is also effectively used as insulation jacketing in power stations and chemical processing plants.
Warnings
- 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.

Materials
PERMALITE LT7™, PERMALITE ALSPAN™ and PERMALITE V-RIB™ are manufactured entirely from marine grade aluminium alloy with exceptional resistance to corrosion in marine or industrial environments.
The profiles are available in three finishes:
- Mill Finish - a 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 prepainted 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.
The paint systems commonly used are:
- Polyesters - These coatings have outstanding colour and gloss retention characteristics and are suitable for exterior roofing and walling applications in all but the most severe environments.
- Fluorocarbons - Premium coatings with excellent weatherability and durability. These coatings are recommended for severe marine and industrial environments.
