Co-Extrusion WPC Hollow Decking

139 × 22 mm
Co-Extrusion Hollow Core 139 mm Width 22 mm Thickness
Co-Extrusion WPC Hollow Decking

This co-extrusion WPC hollow decking profile measures 139 mm in width and 22 mm in thickness, featuring a co-extruded protective cap layer over a hollow core structure. The co-extrusion process integrates UV stabilizers and color pigments into the surface layer, providing enhanced durability and color retention. The hollow core design reduces weight while maintaining structural performance. Suitable for exterior decking, terrace flooring, and balcony applications requiring superior weather resistance and long-term color stability.

Core Advantages
Co-Extrusion Protection
Integrated UV-stabilized cap layer provides superior color retention and resistance to fading, chalking, and surface degradation.
Hollow Core Lightweight
Internal hollow cavities reduce overall weight by approximately 30 percent while maintaining structural integrity and load-bearing capacity.
Weather Resistance
Engineered to withstand UV exposure, moisture, and temperature fluctuations without warping, cracking, or surface degradation.
Slip-Resistant Surface
Embossed wood grain texture provides safe walking surface with enhanced traction in both wet and dry conditions.
Low Maintenance
The co-extruded surface eliminates the need for painting, staining, or sealing. Simple cleaning with water maintains appearance.
Pest and Rot Resistance
Closed-cell structure and co-extruded barrier prevent moisture absorption, eliminating rot and insect infestation risks.

Product Characteristics
Co-extruded cap layer
Protective surface layer integrated during extrusion for superior UV resistance, color stability, and wear resistance.
Hollow core design
Internal cavities reduce material weight while maintaining structural performance and load-bearing capacity.
Weight per meter
Approximately 2.0 to 2.4 kg per linear meter, lighter than solid core with comparable strength.
Edge profile
Square-edged design with slight radius for clean appearance and comfortable walking surface.
Co-Extrusion Technology
The co-extrusion process creates a dual-layer decking profile where the protective cap layer is fused to the WPC core during manufacturing. This integrated construction eliminates the risk of surface delamination, provides consistent color throughout the panel, and offers superior UV protection. The hollow core reduces weight without compromising structural performance.

Frequently Asked Questions
01 What is co-extrusion technology in decking? ⌃
Co-extrusion is a manufacturing process where a protective cap layer is fused to the WPC core during extrusion. This creates a durable, UV-resistant surface that is bonded at the molecular level, eliminating delamination and providing superior color retention compared to traditional WPC decking.
02 How does co-extruded decking compare to standard WPC? ⌃
Co-extruded decking offers superior UV resistance, color stability, and surface durability compared to standard WPC. The protective cap layer prevents fading, chalking, and surface degradation, extending the product lifespan and maintaining appearance with minimal maintenance.
03 What is the recommended joist spacing for this profile? ⌃
For the 22 mm thick co-extrusion hollow decking, maximum joist spacing of 400 mm center to center is recommended for residential applications. Reduce to 350 mm for commercial applications or areas with heavy foot traffic.
04 How to clean co-extruded decking? ⌃
Use a broom or leaf blower for debris removal, followed by low-pressure water rinsing. For stains, use mild detergent with water and a soft brush. The co-extruded surface is stain-resistant and does not require sealing or special treatments.
05 What is the expected lifespan of co-extruded decking? ⌃
With proper installation and minimal maintenance, co-extruded decking typically lasts 25-35 years. The protective cap layer provides long-term protection against UV degradation, ensuring color and performance throughout the product lifespan.
Storage & Installation Notes
Store decking boards flat on level surface, stack height under 1 meter. Acclimate for 48 hours at site conditions before installation. Use stainless steel or coated fasteners. Leave 3-5 mm expansion gaps between boards. The co-extruded surface requires no sealing or painting. Warranty: 15 years against manufacturing defects.
