PU square bar is a high-strength material made by mixing polyurethane resin and glass fiber under high pressure. It is mainly used for box truck body panels and has the characteristics of corrosion resistance, durability and no deformation. It can also be used in ships, construction and other fields.
- Size: 200*42mm (Customized)
- Material: Fiberglass+Polyurethane
- Thickness: 8.5~22mm (Customized)
- Density: 500~700kg/m³
