You need to know while installing WPC material

Most of the wood fiber content in WPC products is greater than 50%. this material also played some aliases, such as severe tension “waterproof wood”, “green wood” and other global timber resources for wood floor to provide a broad space for development. “The following precautions during installation wood materials should be done.

First, with regard to cutting and drilling wood materials, some tips while using alloy saw and drill: thin tooth blade (such as 45 cm in diameter, 18-24 tooth) cutting easier, unlike wood, WPC is easier to be drilled, and you do not have to consider the use of WPC wood grain direction or nodes.

When drilling deeper or larger holes, to be exit debris yourself, do not always want disposable drilled.
Second, while installating, under normal circumstances, the WPC joists gap is 30-50 cm (depending on the size of the profile).

Self-tapping screws is the preferred installation profiles.

When using special screws to install, you must pre-drilling. Pre-drilling diameter should be less than 3/4 straight nail or screw diameter.

When the profile is wider than 10mm, each end should be two screws.

Third, the gap between wpc materials should be taken into account when installing the drainage, cleaning, and a slight thermal expansion or contraction and other reasons, when the bar is mounted, side to side, must leave adequate clearance between 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 the WPC head to head size depends on the length of the profiles, the temperature during installation, the thermal expansion coefficient profiles (ζ≈0.9 × 10-4), as well as local highest possible temperature.

Head to head clearance calculation method:

For a L-meter-long sections, local maximum possible temperature within a year of Tmax, the temperature of the installation is T, then install the root profile head should be retained gap Δ L = ζ × (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 root sections installed head clearance should be retained:

Δ L = ζ × (Tmax- T?) × L = 2000 × (40-10) × 0.9 × Note: 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 concrete, roofing or roof and so on.

(1) WPC railing when used, must be lined with steel or steel, and the same floor to be absolutely firm, railing lining column spacing requirements per 450mm, to prevent deformation fall.

(2) Wood for the 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.

(3)WPC has certain characteristics of 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.

(4) When the profile is installed upright, and a length greater than 3 m, each end use four pairs of clamp screws.
