The PVC Step-Roofing Extrusion Line is primarily used to produce rigid PVC roofing sheets, which are widely applied in the construction industry, particularly in roofing and waterproofing projects. Below are its main application areas:
Building Roofing
PVC step-roofing sheets are commonly used in large-scale structures such as industrial plants, warehouses, greenhouses, and sports stadiums due to their lightweight, weather resistance, and waterproof properties. The step design facilitates drainage and prevents water accumulation.
Waterproofing Projects
Rigid PVC sheets offer excellent resistance to acids and alkalis, making them suitable for corrosion-proof and waterproof applications in chemical plants, wastewater treatment facilities, and similar environments.
Greenhouses and Agricultural Facilities
PVC roofing sheets provide good light transmission and UV resistance, making them ideal for greenhouses, livestock farms, and other agricultural structures that require controlled lighting and environmental conditions.
Temporary and Modular Buildings
Due to their lightweight and easy installation, PVC sheets are often used in temporary shelters, disaster-relief housing, and modular construction.
Commercial and Public Facilities
PVC step-roofing sheets are also widely adopted in commercial and public spaces such as shopping malls, train stations, and airports, thanks to their aesthetic appeal and durability.
Additionally, optimizing the extrusion process (e.g., filler ratios, temperature control) can further enhance the mechanical properties and weather resistance of the sheets, expanding their suitability for more extreme environments.
