GRP Coated Plywood Sandwich Panel
GRP plywood sandwich panels are high-performance composite materials. Made from GRP laminated with marine-grade plywood. Enhance the waterproof and moisture resistance of plywood to prevent rotting. They replace traditional steel and aluminum panels. Service life of up to 40 years. Reduces weight by more than 40% compared to traditional metal panels. They are used in the production of kitchen cabinets, furniture, camper trailers, and box trucks.
Why use GRP-coated plywood panels?
GRP is a stabilized composite material. It has lightweight and high-performance benefits, and is water and moisture resistant. Marine-grade plywood makes better use of timber. It has several layers of thin wood glued together. Layers are cross-laminated at 90 degrees. GRP protects marine-grade plywood from moisture and corrosion. Enhances the impact and bending resistance of plywood. It protects the exterior from scratches and insulates from air. It makes the sandwich panel easier to maintain.
Uses integrally formed composite panels for greater strength and structural integrity. It improves stability and impact resistance.
Advantages of GRP-coated panels:
- Smooth
- Water- and moisture-resistant
- Scratch resistant
- Easy to work with.
- Long service life
Structure:
- GRP coated: The matrix of GRP is resin. This resin covers the exterior. It boosts waterproof performance, impact resistance, and bending resistance.
- Glue: High-quality glue that prevents gluing and cracking and provides good stability.
- Plywood: as a core material, it is a strong, lightweight, and stable material.
