WPC is the recent development of a new material, it is light, rigid, acid, water pest control, environmental protection, in the field of building materials, municipal facilities, packaging materials and other widely used by consumers WPC wide range of applications, you must ensure proper clearance when WPC installed and mounted directly on the joists. Do not WPC fixed directly on any solid surface, such as wood flooring, concrete, roofing or roof and so on. Plastic is a profile, many hollow specifications. Wood for pavilion or flower time, to consider the thermal expansion coefficient, and the columns and beams absolute must lined pipe, and vertical to be securely connected. There are certain characteristics of wood plastic, so that when the length is greater than three meters, the material has a certain degree of bending, easily corrected to normal installation, if the wood is a cross-sectional profile, its bending deformation is relatively increased. Installation is able to basically correct place. When upright when the profile is installed, and a length greater than 3 meters, each end use four pairs of clip screws. And the vertical screw pitch more than 40cm, so that each side four screws average force. WPC for the railing, you must lined steel or steel, and the same floor to be absolutely firm, railing lining column spacing requirements per 450mm, to prevent deformation fall. Wood's life, generally up to 3-4 times the normal wood, choose wood products is your good choice.
