SPC ndi chidule cha miyala pulasitiki gulu, kwenikweni kumasuliridwa ngati mwala pulasitiki gulu zakuthupi, amatchedwa miyala pulasitiki pansi, amene ndi mtundu wa PVC pansi. Choyamba, tiyeni tiwone milandu ya pansi:
Kuyika pansi kwa SPC kumagwiritsa ntchito zinthu zopangidwa ndi miyala ya pulasitiki, yomwe imadziwikanso kuti RVP (rigidvinyl plank), pulasitiki yolimba ku Europe ndi United States. Zida zazikulu zapansi pansi ndi utomoni wa PVC ndi ufa wamwala wachilengedwe (calcium carbonate).
Zomwe zili pansi pa calcium carbonate ndizokwera kwambiri, motero kusalimba kwa zinthu zoyambira ndi kuuma kwa pansi kwa pulasitiki yamwala ya SPC ndikokwera. Pansi ndi yokhazikika, yolimba komanso yodalirika, imakhala ndi mphamvu zamakina, komanso kukana kwambiri komanso kutulutsa. kukakamizidwa, kukana mphamvu.

Izi zimapewa kugwiritsa ntchito guluu ndikukwaniritsa zero formaldehyde kuchokera kugwero.
Monga mtundu wa PVC pansi, SPC yazokonza pansi wakhala chimagwiritsidwa ntchito m'mayiko monga Europe, United States, Japan ndi Korea South. Chifukwa chomanga bwino, mtengo wotsika, mitundu yolemera, kutetezedwa kwachilengedwe kobiriwira ndi mawonekedwe ena, pang'onopang'ono ikusintha pansi pamatabwa ndi nsangalabwi ndikukhala chokongoletsera chamkati chamkati.
