The raw materials, extrusion methods, and installation of wood-plastic flooring determine the quality of use. When installed, it is not easy to be deformed according to requirements. If the plastic materials used are poor, they are easily deformed. Therefore, it is best to buy large manufacturers when purchasing, there are guarantees, some manufacturers use imported plastic materials, there will be no thermal expansion and contraction, and deformation. The ground should be leveled before installation, and the tools used should be equipped with the manufacturer, so the decoration works well. To master the distance between the floors and the distance between the floor and the wall, etc., the installation method is not correct and it is easy to cause deformation.
