Aluminium Skin As a result of this technology, we Adhesive Layer have created a perfectly flat and Polyethylene Core very formable material with an excellent strength-to-weight ratio. Alupanel is supplied with a face PE paint finish, available in the widest colour range on the market. The versatility of the panel makes it a perfect material for sign makers, designers, architects, fabricators and installers. Advantages include: - Exceptional rigidity - Outstanding strength to weight ratio - Simple to fabricate - Easy and quick to install However, since skill, judgment, In no event shall Multipanel UK - High resistance to and quality of equipment and tools Ltd, have any liability in any way atmospheric conditions are involved, and since conditions related to or arising out of said - Easy to maintain and methods of using Alupanel are suggestions and product data for beyond our control, the direct, special, consequential or This manual has been developed suggestions contained in this to assist fabricators and any other damages of any kind. manual are provided without installers to work with Alupanel in guarantee.
