PU foam cored FRP composite panels are made of prefabricated fiberglass reinforced plastic sheets as inner and outer surfaces, PU foam ad core and high-strength adhesive bonding together under high vacuum pressure. The gelcoat on surfaces are FDA approved, friendly to food.
Advantage: light weight, high impact resistance and strength, corrosion resistance, smooth and glossy surface, UV ad weather resistance, good insulation, easy to repair, long time using. Custom made aluminum extrusions to join body panels giving easy assembly. Bodies can be supplied either fully built or in CKD form.
Thickness: 30mm, 45mm, 70mm, 105mm, 130mm, can be customized.
Sizes available: 16.5m long and 3m wide at maximum.
