ALUSONG Hollow panel features a corrugated plastic core sandwiched between two 0.30mm aluminium skins coated with a superior polyester paint finish. This innovative core structure makes a strong, lightweight panel, offering easy handling and providing maximum strength and stability. ALUSONG Hollow panel has an easy-peel protective film and is the perfect base for vinyl. The panels are rigid, easy to install and can be easily fabricated for folding and forming. They are much lighter than standard Aluminium Composite Panels making them ideal for many applications.
ALUSONG Hollow panel are painted by a high-gloss, factory-baked, polyester paint coating.
The finish is smooth, durable and dirt resistant. It will not crack, chip, flake or peel even under harsh weather conditions. Colors shown are as the same as ALUSONG other products series as per customer’s request.
