Alstone is made out of two Aluminium skins, which are precoated and thermally bonded to each side of non-toxic polyethylene core. Adhesion achieved by combination of chemical and mechanical actions, thereby providing exception resistance to delamination.
The outer Aluminium skin is precoated with PVDF 70/30 (Polyvinylidene fluoride) coating, which is the most advance coating used in building sector because of its excellent stability over the time in all respect. Where as the inner aluminum skin is precoated with a service coat to protect the inner skin from either alkali attack from cement or galvanic corrosion from steel.

Features
  • Alstone The Versatile Alternative
    Excellent color uniformity- A very high end technology is used to coat the aluminium skin with quality colors and ensures accurate color constancy. Uniform flatness-Alstone Aluminium Composite Panels are absolutely flat and free from any distortion.
  • Light Yet Rigid
    Alstone aluminium composite panels weigh 3.4 times less than steel and 1 times less than aluminium and yet compete equally when it comes to rigidity.
  • Hassle Free Maintenance
    Alstone aluminium composite panels require little or no maintenance during their lifetime. In fact, by simply wiping them with a normal detergent you can keep them in mint condition for years
  • Reduction Of Construction Lead Time In Final Stages
    Alstone Aluminium composite panels enable comprehensive cladding process to be carried out at a faster pace by using various fastening system. They are even being used to change the appearance of old buildings by their sheer look and long life.
  • Built To Last Long Time
    Alstone aluminium composite panel are manufactured under stringent quality at Alstone's start-of-the manufacturing facility at Dehradun, Uttaranchal. It is managed by its team experienced engineers and technocrats drawn from the industry.

SUGGESTIONS:-
To ensure colour consistency, the total requirement for a project is advised to be placed in one order. It is also recommended to install the panels in the same direction as marked arrow on the protective peel-off-film to avoid possible reflection differences.
Custom colours are also available upon request for solid colours, metallic colours and special finishes such as mirror, brush finishes etc. subject to the respective minimum quality Colour may vary from batch to batch. (±.?5)
