Below are answers to the most common questions about product quality, performance, installation, customization, and international cooperation.
Technical Specifications & Durability
1.What is co-extrusion technology?
Co-extrusion is an advanced surface protection technology used in premium WPC products.
A protective polymer layer is bonded around the WPC core, providing enhanced resistance against:
- UV exposure
- Stains
- Scratches
- Moisture
- Color fading
Compared with traditional WPC products, co-extrusion decking offers improved outdoor performance and a longer-lasting appearance.
2.How long can WPC products last?
With proper installation and normal outdoor conditions, our WPC products are designed for long-term outdoor use.
Depending on climate conditions, application environment, and maintenance, WPC products can provide a service life of approximately 15–25 years.
How does WPC perform in extreme weather conditions?
Our WPC formulations are developed for outdoor environments and provide excellent resistance against:
- Moisture
- Temperature changes
- UV exposure
- Daily weathering
The products maintain structural stability under different climate conditions.
For projects requiring specific temperature or environmental performance, our technical team can provide detailed recommendations.
3.Are WPC products termite resistant?
Yes.
The polymer component in WPC makes the products naturally resistant to termites, insects, and fungal decay.
Compared with traditional wood, WPC requires less maintenance and provides better long-term outdoor durability.
4.What is the recommended joist spacing for WPC decking?
The recommended joist spacing is generally:
300–400mm
depending on:
- Decking profile structure
- Board thickness
- Application area
- Required load capacity
For commercial projects or special applications, we provide technical recommendations based on project requirements.
5.What is the difference between hollow and solid WPC decking?
Hollow WPC Decking
Advantages:
✓ Lightweight
✓ Cost-effective
✓ Easier transportation
✓ Suitable for residential applications
Solid WPC Decking
Advantages:
✓ Higher strength
✓ Better load-bearing performance
✓ Suitable for commercial areas and high-traffic locations
Our team can recommend the right profile according to your project needs.
6.Will WPC decking fade over time?
Like all outdoor materials, WPC may experience slight natural color changes after long-term UV exposure.
Our products include UV-resistant additives to improve color stability.
Premium co-extrusion WPC products provide enhanced protection against fading and weathering.
