PVC Formed Slats - Smooth

QUALITY: Usually, manufacturers only use one extruder to produce PVC slats because of the cost down. We use second extruder to cover the PVC slat because we can add special material to resist UV, so our slat can prevent discoloration, bowing, deformation and increasing surface hardness. Also, our special water to prevent the dirty stuff to adhere on the surface of PVC slat. You can see our pictures as follow; the centre extruder produces PVC slat, and we have one more extruder on the left to cover.
PS. Please do not ask us what are special material and special water because we need to prevent other people copy.
