Co-extrusion composite decking is the smart way to get a great-looking, long-lasting deck
What is Co-extursion WPC decking?
Co-extrusion is the second generation WPC product, Co-extrusion is also called “capped” or “cover” deck. It is important distinction to note because that earlier generations of composite decking were uncapped, the big difference is that Co-extrusion wpc has a “cover” that provides added protection against the elements and everyday living. As a result, they were far more vulnerable to staining and fading. Of course, when we say cap or “cover” we don’t mean something that is added after the composite decking is made, the cap is bonded to the core during the manufacturing process.
Sundi Co-Extrusion Deck – The new generation of wpc
Sundi Co-extrusion composite decking is the new generation made by co-extrusion, which is the latest technology in the industry. Co-extrusion decking is composed of core and cover. The core is just the traditional wpc decking, which is sufficiently ensure the strength of materials. The cover protects from color-fading away, water-absorption and with longer usage time. Performing better than any traditional composite:
Co-extrusion process creates strong, resilient boards with lasting good looks
Sundi Co-extrusion decking, the core is the traditional wood plastic composite materials (along with our G series and H series traditional decking), while the extruded surface is made of multi engineer plastic with an outer shell of plastic that completely encapsulates the board in an impermeable layer of protection from scratches, stain and fading. The extrusion process creates the decking with highly durable, long lasting and resistant to staining, fading and relative impact.
Compared with traditional wood plastic composites, the Co-extrusion deck has many advantages:
1.     Better resist to scratch;
2.     Better resist to UV, better color stability;
3.     Better resist to moisture and termites;
4.     Extreme durability and reliable: less water-absorption, less rotten, wear proof;
5.     More natural surface: wooden texture, looks like real wood.
6.     More durable, more attractive, more fade and scratch resistant, more beautiful and more reliable.
7.     Low maintenance at an excellent price.
