Traditional wooden decking has been the material of choice for both indoor and outdoor decoration for a long time. But more and more people are turning to the new wood-plastic composite decking. Unifloor WPC decking is made from wood fibers and recyclable plastic. The reasons that have contributed to this shift include the following.

Wood-plastic composite decking has greater durability and weather resistance. In contrast, traditional wood flooring is more susceptible to weather factors. Because of temperature differences, expansion or contraction will happen. Because of moisture accumulation, mold can be accumulated. Rot due to termite infestation. Discoloration due to prolonged sun exposure. In order to maintain a long-lasting beauty, the color needs to be repainted periodically. Wood-plastic composite flooring is not easy to fade.

Wood plastic composite flooring is easier to maintain. Generally speaking, traditional wood flooring needs to be brushed once a month and oiled at least once a year to prevent it from warping or rotting. And wood plastic composite flooring is more popular because it requires little maintenance.

Wood plastic composite flooring is very easy to install. It is easy to cut and has a hidden fastener system to meet both stability and beauty.
