WPC profile is easy to use, no need to select grainy direction and structure point like wood when cutting.
When you drill a big or deep hole, it is better to draw out the drill timely to bring out the scraps.
Storing and Handling
WPC profile has a bigger specific gravity compared with wood, it has to pay more attention when handling.
Considering its plastic property of WPC, it has to lay flat on the work place when storing.
When stack WPC profiles, the distance of two nearby beams should be with 60cm, and keep profiles and beams are vertical together.
Normally, WPC profiles require max 60cm width of span between two nearby beams, and at least 3 beams per panel.
Self-thread nail is preferred to install WPC profiles, minimum diameter is 5 mm and length is changed according to the thickness of WPC profiles, normally between 50-60mm. To avoid nails be rust, it's better to use stainless steel nail or nickel plated. Please do not use zincification plated nails.
It's more laborious to nail on WPC profiles than wood. It's better to nail into 1.5-2cm first and then use full force to fix the whole nail.
When cold weather or use bolt. it has to drill a hole first, diameter should be smaller than 314 diameter of bolt. 3-4 need normally 2 nails to fix on the width direction of WPC profiles, especially the two end of the panel.
Side to Side : Minimum 6mm gaps, and at least l0 mm when install in cold weather.
End to End: This Gap depends on length of profiles, install temperature, thermal expansion, and the possible highest local temperature. The calculation of gaps between end to end is as follows : Furs L long WPC profile, highest local temperature is T-max, install temperature is T. then the gap between end to end should be delta.
Cleaning and Maintenance
Considering of drain, clean, small heat expand and cold contract, it has to leave suitable gaps between and side to side up to the end.
Pollution caused by berry and leaf mold, use abluent contains sodium hypochlonte or detergent.
Iron rust and dusty, use abluent contains phosphoric acid.
Oil pollution, use degrease abluent.
Timely clear the litters in the gaps, to keep the drain system works smoothly.
