about wood plastic composite lumber suppliers


Wood Plastic Composite Decking is an attractive and very durable and low maintenance decking solution that will withstand the test of time. Each piece is knot free and consistent in size, colour and length, therefore eliminating the search for the perfect piece. The beauty of this Eco Friendly deck is the look, the close match to the natural wood and this unique recycled decking solution has the durability of plastic. about wood plastic composite decking
Each board in the process of manufacturing is protected with UV inhibitors to ensure long-lasting colour. WPC decking is sturdy, durable, and versatile enough to provide year's maintenance free service. Weather and none slip resistant surface also make it ideal for outdoor decking around swimming pools boat decks and decks of all types.
WPC decking is an attractive and dependable decking solution that will withstand the test of time. Each piece is knot free and consistent in size, color and length. WPC decking looks, smells and handles like wood but has the durability of plastic, it is UV treated to last. We export Wood Plastic Composite (WPC) worldwide.

What is WPC composed of and how is it made?

WPC is composed of 55% waste wood and 45% thermal plastic resin waste plastic. Waste wood is retrieved from demolition sites, lumber mills, factories, wood shops and other sources utilizing wood as a basic raw material in the production of goods. The waste wood is the retrieved and ground to hundreds of microns and is then mixed and kneaded with the waste plastic. The resulting WPC mixture is extruded with heat through custom made molds and cooled with water immediately thereafter.
Because it is made from waste products and 100% recycled materials. Accordingly, when compared to the felling, stripping and lumbering of natural wood, the production of WPC is more environmentally friendly. Although energy produced and used in manufacturing WPC results in a certain amount of C02 emissions, such emissions are minimized by exhaust scrubbing thereby minimizing and negative impact on the environment. Because the extrusion process allows nearly 100% material usage, there is almost no waste of the recycled input materials used in making WPC. about wood plastic composite lumber
There are also problems associated with using naturally rot-resistant wood species, such as redwood and cedar. Clear-heart redwood is generally cut from old-growth forests. Redwood trees take a long time to mature, and there are very few remaining stands of privately owned redwood. Small but increasing amounts of redwood and cedar are available from certified, well-managed forests. The quick-growing second-growth redwood and cedar, with wide growth rings, is less resistant to rot and insects than old-growth wood.
Sustainably harvested, long-lasting exotic hardwoods such as Ipé, imported from Brazil and Bolivia, are increasingly available; look for Forest Stewardship Council (FSC) certification. FSC certification involves third-party evaluation and monitoring of sustainable forestry practices—and chain-of-custody verification that wood products were derived from certified forests.
There are many solid sustainability arguments for making composite lumber part of the design for a home or office.
This material is a recycler's dream, mixing together scrap plastic and wood fiber wood mill sawdust into relatively stable boards that have been used for outdoor decks and railings, garden accents, trim and window frames, and even for interior flooring, to name a few options. about wood plastic composite lumber suppliers
Composites have as many different formulas as there are products, but generally recycled wood/plastic composite lumber consists of a 50/50 mix of wood fibers from recovered saw dust and waste plastics that include high-density polyethylene and PVC.
The material is formed into both solid and hollow profiles. Recycled wood/plastic composites are typically more rigid than 100 percent recycled plastic lumber because the wood fibers act as reinforcement. about wood plastic composite manufacturers
