Composite panel incorporates modified polyethylene plastic core in middle and is enclosed with non-flammable aluminium layers on both sides. It is then coated with PVDF coating to provide different colour on the panel surface. Both type of panel is strong, durable and heat resistance and is widely used for building awing, roofing, shelter, walkway, etc. Structure for the polycarbonate and composite panel roof can be either metal or timber.
