JoistWPCKeelForFlooringWallPanel is a joist system made of wood-plastic composite (WPC) material, designed to support prefabricated panels for floors, walls, and ceilings. Products include standard DoubleKeel and optional SteelKeel options to meet varying project sizes and budgets. Its cross-sectional dimensions are approximately 40mm x 25mm, and a recommended installation spacing of 30-35mm ensures a flat and stable panel.
Advantages
1. High Strength and Durability: WPC joists offer excellent compression and bending resistance; SteelKeels are more durable and suitable for large-scale projects.
2. Corrosion and Moisture Resistance: WPC is naturally waterproof and moisture-resistant, making it suitable for outdoor and humid environments.
3. Insect-Resistant and Flame-Retardant: Termite-resistant, mildew-resistant, and flame-retardant, it meets building safety requirements.
4. Low Maintenance and Long Life: No paint treatment is required, with a service life of up to 15 years and requiring only occasional cleaning. 5. Multiple Color Options: Available in 12 standard colors, including black, coffee, brown, gray, and mahogany, to meet your decorating needs.
6. Environmental Certification: Obtained multiple international certifications, including CE, SGS, ISO, FSC, and INTERTEK.
Easy Installation: Double keels are designed for panel joints, ensuring overall flatness. With a 30-35mm spacing, installation is quick.
7. Cost Flexibility: Standard WPC keels offer high cost-effectiveness. Steel tube keels, while slightly more expensive, provide stronger support. Choose the right one based on your budget.
