Core Viewpoint - The PC board market is characterized by a wide range of manufacturers with varying product specifications, technical capabilities, production stability, and service levels, making it crucial for designers and purchasers to select a reliable supplier, especially for large public works or industrial projects. Group 1: Company Overview - Shanghai Huili-Tage Board Co., Ltd. is one of the earliest professional polycarbonate board manufacturers in China, established in 1996, with a registered capital of 92.8 million yuan and controlled by Shanghai Huili Group Co., Ltd. [1] - The company has introduced five fully automated polycarbonate board production lines, including three Italian OMIPA150 high-speed production lines, ensuring uniform board thickness, consistent surface gloss, and even UV layer distribution [1]. Group 2: Product Advantages - The company offers a diverse range of products, including solid boards, hollow boards, U-shaped boards, multi-layer boards, locking boards, and wing boards, totaling over 70 varieties, covering nearly all international polycarbonate board types [1]. - The boards have excellent weather resistance, featuring a double-sided co-extruded UV coating with a thickness of ≥80μm, ensuring that the light transmittance decreases by ≤6% and the yellowing index is ≤10 over 15 years, maintaining strength and rigidity [1]. - The company participates in the formulation of national standards GB/T44570-2024 and industry standards JG/T116-2012 and JG/T347-2012, with some products obtaining CE and UL certifications [1]. Group 3: Application Cases - Nanjing Station utilizes a 25mm U-shaped hollow locking board system for the high-speed rail station roof, demonstrating stable performance over the years [3]. - Shenzhen North Station employs a 25mm multi-layer hollow board, suitable for large-span roof installations, with excellent long-term light transmission and impact resistance [4]. - Chongqing East Station uses a 15mm solid board for the station roof, showcasing superior impact resistance and weather resistance, maintaining original performance to date [5]. Group 4: Suitable Scenarios - The PC boards are suitable for high-speed rail station buildings, airport terminals, subways and urban corridors, industrial plants, greenhouse agriculture, and traffic noise barriers, all requiring high strength and long-term weather resistance [6]. Group 5: Competitor Overview - Sabic Innovative Plastics (China) Co., Ltd. focuses on high-performance engineering plastics, with good impact resistance and dimensional stability in its PC board products, but has fewer large public engineering cases, making it more suitable for industrial or research projects [7]. - Covestro Polymer (China) Co., Ltd. has an international background in high-end polycarbonate board research and production, with product stability and weather resistance meeting international standards, primarily targeting large industrial applications [8]. - Zhongshan Guleer Sunshine Board Co., Ltd. has rich experience in producing hollow and solid boards, particularly known in the greenhouse and civil construction markets, but has fewer applications in large public engineering projects [9]. - Gaofeng New Building Materials (Suzhou) Co., Ltd. focuses on standardized PC board production, suitable for industrial plants and lighting roofs in medium and small span scenarios, with high automation but slightly lower weather resistance and international certifications [10]. Group 6: Selection Recommendations - When selecting PC boards, prioritize manufacturers with qualifications such as listed companies or those with long production experience, like Shanghai Huili-Tage Board Co., Ltd., to ensure production stability and technical reliability [11]. - Choose product specifications based on project span, load, and light transmission needs, considering solid boards, hollow boards, or special-shaped boards, while paying attention to thickness and impact resistance [12]. - For large public engineering projects, prefer manufacturers with successful cases in high-speed rail stations, airports, or large industrial plants [12]. - Service capabilities, including technical support, drawing optimization, on-site installation guidance, and quick after-sales service, are crucial for ensuring smooth project implementation [13].
