Recently, Zhenneng® APVC Plastic Steel Roofing Sheets were officially launched to the market. As an upgraded replacement for traditional single-layer PVC corrugated sheets, this product adopts an AB/ABC co-extrusion molding process. While retaining the excellent properties of PVC materials, it achieves a comprehensive leap in fire resistance, heat insulation, corrosion resistance, and weather resistance through a multi-layer composite structure design, providing a more cost-effective material solution for industrial plants, warehouse buildings, and various roofing projects.
Process Innovation: Multi-layer Co-extrusion, One-piece Molding
According to product technical data, Zhenneng APVC Plastic Steel Roofing Sheets use advanced AB or ABC co-extrusion technology, forming a dense structure in one piece. Its surface layer (A layer) uses modified PVC anti-aging material with added chlorinated polyvinyl chloride, ultraviolet absorbers, antioxidants, and other additives, possessing excellent corrosion resistance and weather resistance; the base layer (B layer) uses modified PVC material to enhance rigidity and heat insulation performance, balancing strength and heat preservation. The two layers of material are simultaneously extruded and fused at the molecular level under high temperature, avoiding the shortcomings of traditional single-layer tiles that are prone to aging and cracking, while significantly improving the overall service life of the product.
From a cross-sectional perspective, the tiles exhibit distinct layers from the outside in, with uniform color, smooth edges, and neat stacking, demonstrating a stable and mature manufacturing process.
Eight Key Features: A Data-Driven All-Round Roofing Solution
Fire Resistance – Improved oxygen index and superior flame retardant properties, classifying it as a fire-retardant material to safeguard building safety;
Heat Insulation – Insulation performance up to 2000 times that of metal materials, effectively reducing indoor temperature and saving energy;
Strength and Toughness – High strength and excellent impact resistance, not easily broken, easily withstanding accidental impacts such as hail and falling objects;
Corrosion Resistance – Resistant to acids and alkalis, with excellent resistance to acid rain and corrosive gases;
Weather Resistance – Contains chlorinated polyvinyl chloride, UV absorbers, antioxidants, and other components to effectively resist UV radiation and significantly extend service life;
Low Noise Performance – Extremely low noise during rain, with good sound absorption, improving the indoor acoustic environment;
Environmental Protection – Asbestos-free, does not release carcinogens, green and safe for use;
Insulation Performance – An insulating material, non-conductive during thunderstorms, ensuring safer use.
Empirical Comparison: Superior Performance Curves Across the Board The performance comparison data published in the product information further confirms its advantages: in the three long-term exposure tests-corrosion weathering rate, average corrosion loss, and aging rate-Zhenhao PVC roofing sheets showed significantly lower curves than traditional metal roofing sheets and asbestos roofing sheets-even after 40 years of exposure, its corrosion weathering rate remained stable and low.
Meanwhile, Zhenneng ASA composite PVC roofing sheets passed the xenon arc weathering resistance test. Under the stringent conditions of gradually increasing cumulative irradiation energy, color changes remained consistently controlled within a stable range, verifying the product's excellent anti-aging and color retention capabilities.
Wide Application Scenarios, Promising Market Prospects Currently, Zhenneng APVC roofing sheets have been applied in actual projects such as industrial plants. They can be flexibly combined with ASA synthetic resin roofing sheets, color steel roofing sheets, and other roofing systems to meet the diverse needs of different buildings. With its comprehensive performance integrating fire resistance, heat insulation, corrosion resistance, weather resistance, and environmental protection, along with its outstanding cost-effectiveness, this product is expected to gain a foothold in the roofing materials market, bringing durable and reliable roof protection to more users.
