WPC (Wood Plastic Composite) frames are modern, durable door frames made from a mixture of wood fibers, thermoplastics, and additives. They are 100% waterproof, termite-proof, and dimensionally stable, making them a low-maintenance, long-lasting alternative to traditional wooden frames. Commonly used for bathrooms, kitchens, and main entrances, they are environmentally friendly, cost-effective long-term, and do not warp.
