The main purpose is to replace the difference between wood timber, wood and pine, poplar, eucalyptus and other natural wood is that it is a kind of plastic and wood fiber synthetic "wood"; the current production of wood composite products of wood Most of the fiber content is greater than 50%, wood-based,adding pool and deck to existing deck home and abroad, this material also played some aliases, such as severe tension "waterproof wood", "green wood" and so on, global timber resources for wood floor to provide a broad space for development. "Some say the following precautions wood materials in the installation process should be done. First, on the wood material cutting and drilling, we recommend using alloy saw and drill tips: dilute tooth blade (such as diameter 45 cm, 18-24 tooth) cutting easier.
WPC profiles very easy to use, unlike wood, when you do not use Furui Sen WPC consider wood grain direction or nodes. When drilling large or deep holes, withdraw the drill bit to be timed to bring out the debris, you do not always want to disposable drilled. Second, the installation on wood materials, under normal circumstances, when WPC joists span of 30-50 cm (depending on the profile size). , Self-tapping screws durability, is the preferred installation WPC profiles. When using special screws during installation, you must advance drilling. Pre-drilling diameter should be less than 3/4 straight nail or screw diameter. discount wood fencing material When the profile width greater than 10mm, each end should be two screws. In particular, use of the environment or abnormal load conditions - such as a hot bath - may require a shorter distance during installation. Third, on the gap wood materials taken into account when installing drainage, cleaning and minor thermal expansion, contraction and other reasons, Hualong profile installation, edge to edge, you must leave appropriate gap between the head of the head. Edge to Edge: WPC side to side between the requirements of ��4 mm: When installed in a cold climate, ��4 mm clearance requirements.
Head to head: the gap between WPC profile head to head size depends on the length of the profiles, the temperature during installation, the thermal expansion coefficient profiles (�ơ�0.9 �� 10-4), as well as local highest possible temperature. Head to head clearance calculation: For a L-meter-long sections, stylish good neighbor wood fences local highest possible temperature within one year Tmax, the temperature at installation is T, then install the root profile head should be kept gap �� L = �� �� (Tmax? -T) �� L. For example: a 2 m long profile, installation day temperature of 10 ��, the hottest day of the year the temperature is 40 ��, then when the head of the root profile installation clearance should be retained: �� L = �� �� (Tmax- T?) �� L = 2000 �� (40-10) �� 0.9 �� Note: You must ensure adequate clearance when WPC installed and mounted directly on the joists. Do not put WPC fixed directly on any solid surface, such as concrete, roofing or roof and so on.
