The corrosion resistance can match that of resin boards, effectively resisting corrosion from industrial exhaust, acid rain, and other corrosive media, preventing maintenance and replacement costs due to roof corrosion, and reducing economic losses due to production shutdowns for maintenance. It is particularly suitable for industrial scenarios with strong corrosive environments, such as chemical and metallurgical industries. It has passed the testing by the National Fixed Firefighting System and Fire-Resistant Component Quality Supervision and Inspection Center (Tianjin Fire Research Institute Test Center) and meets the A-level fire protection standard. It can effectively block the spread of fire during a fire, reducing fire hazards and property damage, in line with industrial building fire safety regulations. The surface uses ASA high weatherability resin, which has been applied to the surface of synthetic resin tiles by Fangxing since 2003. Over 10 years of practical application have proven its reliability against aging; the product has passed a 15,000-hour artificial accelerated aging test at the National Chemical Building Materials Test Center, resisting the effects of ultraviolet rays, high temperatures, and severe cold, keeping the roof appearance new and beautiful, and preventing discoloration and cracking due to aging. The ASA high weatherability resin on the surface uses BASF’s advanced infrared reflective technology, with an infrared reflectance rate of over 30%, effectively blocking and reflecting infrared heat radiation; tested by the National Building Materials Test Center, the product’s thermal conductivity coefficient is only 0.601 (w/m.k), much lower than the 6.598 (w/m.k) of color-coated panels, reducing roof heat absorption in summer, lowering indoor cooling energy consumption, and in winter reducing heat loss, achieving energy-saving effects in buildings. The ASA high weatherability resin has a rich and stable color palette, and actual application results by Fangxing show that the product color can remain unchanged for 13 years; in a 15,000-hour artificial accelerated aging test at the National Chemical Testing and Test Center, the color difference (△E) <5, far exceeding the industry average. A rich and lasting color palette not only frees industrial buildings from a monotonous appearance but also provides designers with ample color creative space, giving industrial plants both practicality and artistic appeal. The width of the panel is 960mm (including the effective coverage width), balancing construction efficiency and roof integrity, reducing the risk of leakage from seams; the effective width is 900mm, making the actual coverage area clear and convenient for project budgeting and material accounting; the wave number configuration offers a choice of 3 waves and 51 waves, with the 3-wave profile suitable for large-span roofs, enhancing structural stability; the 51-wave profile is better suited for scenarios requiring higher roof flatness, flexibly matching different architectural design needs; the wave pitch is unified at 450mm, with a scientifically reasonable wave design that ensures roof drainage while also enhancing the overall wind load capacity of the board; TPO sheet thickness is retained at 1.5mm and 1.8mm, allowing for flexible selection based on the roof waterproof level (e.g., 1.8mm for rainy areas, 1.5mm for normal dry areas) to ensure stable waterproof performance; steel plate thickness covers four specifications of 0.5mm, 0.6mm, 0.7mm, and 0.8mm, with light load roofs (e.g., small plants) able to choose 0.5-0.6mm, and roofs requiring high load or high wind resistance (e.g., photovoltaic power stations, coastal buildings) able to choose 0.7-
