Everyone in the industry knows that WPC has many advantages and is widely used, especially in building products. Let’s talk about the application of outdoor WPC products in building products. After years of development, the fastest-growing potential market for wood plastic composite material is the construction products with low requirements for structural functions, including industrial floors, composite doors and window frames, guardrails, landscape materials and so on. These applications are in high demand, and most of the styles are single. Wood plastic composite material a big branch of the industry is the production of doors and windows profiles. The most common plastic matrix is PVC, but other plastics or mixtures are also used. Although the price of wood plastic composite material is higher than that of PVC material, the composite material has won people’s favor because of its thermal stability, moisture resistance and stiffness. At the same time, the wood plastic composite material surface can make wood grain to wait for adornment design, make it has the visual effect that resembles with wood door window, satisfied the sensory requirement of people already, compare lumber again durable. Wood-plastic products are more expensive than preservative-compressed wood panels, but they require less maintenance, less maintenance, less cracking under outdoor conditions, no pollution and corrosion loss caused by the loss of agents, and have higher durability. Anti-corrosion Property of Wood Plastic Deck Due to the excellent moisture resistance and dimensional stability of wood plastic composites material, their applications in garden construction gradually increase, such as the manufacture of tables, chairs, dustbins and so on. The application of composite materials in gardens reduces the great demand for solid wood. Meanwhile, its advantages in processing complex and diverse shapes provide great creative space for garden design, enabling designers to create more beautiful and unique garden artworks than solid wood materials. The actual life of composite products is still controversial, but most manufacturers offer a 10-year guarantee.
