WPC cov qhov rooj muaj cov khoom xws li dej tsis kam, dej tsis kam, thiab kev tiv thaiv rau rot, pwm, thiab kab puas tsuaj, nrog rau qhov ruaj khov. Tshaj li cov qauv siv sab hauv, lawv tsim nyog rau cov cheeb tsam uas muaj qhov kub thiab txias hloov pauv, cov av noo siab, lossis qhov cua tsis zoo- xws li cov chav da dej thiab chav cia khoom uas xav tau kev tiv thaiv rot, pwm, thiab kab tsuag.
Siv ntoo-cov khoom siv yas ua cov khoom siv hauv paus, cov tuam ntxhab tau tsim cov khoom sib txawv uas suav nrog cov qhov rooj sab hauv, cov pwm zoo nkauj thiab cov vaj huam sib luag, cov txee txee, cov qhov rais, cov plag tsev, thiab cov railings. Kev ua lag luam hauv tsev tau ua tiav qhov loj me thiab txuas ntxiv mus. Los ntawm xyoo 2005, WPC-raws li qhov chaw sab nraum zoov decking thiab fencing suav txog 15% ntawm thaj chaw ua lag luam nyob hauv North America, nrog kev kwv yees kwv yees kev loj hlob txuas ntxiv mus txog xyoo 2010. Xyoo 2005, kev muag khoom ntawm WPC sab nraum zoov decking thiab lwm yam khoom siv hauv North America tau txog $ 495 lab. Cov kev kwv yees sib cais tau qhia tias lub ntiaj teb WPC kev ua lag luam tuaj yeem tshaj $ 1.4 nphom los ntawm 2007. Qee lub tuam txhab tau qhia cov khoom siv kho kom haum- xws li dej- thiab ya raws- tiv thaiv WPC qhov rooj- tshwj xeeb tsim rau cov huab cua hauv Middle East. WPC cov khoom pib yav dhau los tau suav nrog hauv Ministry of Science thiab Technology's "863" thiab "948" cov haujlwm.
