Description:
The panel comprises a polyethylene core between two aluminum skins, the thickness of LDPE core and two aluminum skin and the width of panel can be designed according to customers requirement, the front surface is coated with high gloss polyester (PE) paints of more than 90°, the protective film which is on the top surface can be peeled off. The back aluminum skin is done by anti-corrosive pretreatment or coated with anti-corrosive paints. It is enjoyable for sign and advertisement.
