PVC screw barrel is main product of Nanhaiya,high-quality material 38CrMoALA is adopted, combined with special processes such as nitriding and bimetallic alloy treatment. This enhances the wear resistance and corrosion resistance of the screw and barrel, endowing them with a longer service life and reducing maintenance and replacement costs.

PVC foam boards can be used to make background walls, baseboards, door casings, window casings, and more. They serve as a wood alternative, preventing moisture-induced warping or deformation. Additionally, they can be processed into exterior wall cladding, outdoor flooring, fence panels, and other products. These boards resist rainwater and UV radiation, ensuring long-term use without easy aging.
