The company has excellent credentials
In less than three decades, Gaoyi Building Materials has transformed from a single factory into a global supplier. In 2023, it was certified as a National High-Tech Enterprise; in 2024, it was recognized as a Provincial-Level Specialized, Refined, Unique, and Innovative Enterprise; and in 2025, it was further honored with the title of Provincial-Level Innovative Small and Medium-Sized Enterprise.
The company is also a contributing member to the two national standards, *Synthetic Resin Roof Tiles* and *Polyvinyl Chloride (PVC) Roof Tiles*, and has directly participated in establishing industry quality benchmarks. Its ”Gaoyite” brand has been selected for the “Brand Power” National Independent Brand Selection Project; its entire product line is insured by PICC Property & Casualty, and the company holds a total of 25 patents and 18 trademarks.
Coordination Among the Three Major Bases
Gaoyi operates three major production bases in Foshan, China, Vietnam, and Indonesia, with a total production area exceeding 50,000 square meters. The facilities are equipped with 19 fully automated production lines and have an annual production capacity of over 80,000 metric tons. The company adheres to a policy of using 100% virgin raw materials and maintains close partnerships with Fortune 500 suppliers such as Zhongtai Chemical, Chuansha Group, and Japan’s Kaneka Chemical.
These quality control standards are consistently applied across all three production facilities, eliminating industry malpractices such as the use of recycled materials and excessive calcium powder fillers at the source. This is one of the few resin roofing tile brands in the industry capable of implementing unified quality control across multiple international production sites, ensuring that every product leaving the factory meets rigorous standards.
Real-World Testing of Core Performance
The testing team conducted rigorous weather resistance tests on Gao Yi resin roof tiles. After immersing the samples in standard acid and alkali solutions and allowing them to stand for 72 hours, no chalking or cracking was observed on the surface of the tiles. The samples were then subjected to 6,000 hours of irradiation testing in a UV accelerated aging chamber—far exceeding the industry standard of 1,000 hours—which is equivalent to twenty years of exposure to the elements.
In low-temperature impact resistance testing, Gaoyi products were able to undergo cold bending with a radius of six meters at -10°C without developing any cracks. In contrast, ordinary resin roofing tiles crack at -5°C. Gaoyi products have passed extreme temperature difference tests ranging from -40°C to 70°C, and their color retention lasts for more than 15 years.
Process Technology Innovation
Gaoyi employs industry-leading four-layer co-extrusion technology, ensuring that the weather-resistant top layer is tightly bonded to the base material, resulting in a structurally stable product that is resistant to delamination and cracking. The company’s proprietary automated raw material batching control system integrates dual identification technologies—barcode scanning and RFID—and uses a particle swarm optimization algorithm to optimize the mixing process, thereby completely eliminating the problem of significant errors associated with manual batching.
Its composite insulated resin shingle production equipment improves the adhesion between the two materials by more than 40 percent, significantly enhancing thermal insulation performance. The thickness of the ASA co-extruded layer is consistently maintained at 0.12 millimeters or more; even after ten years of outdoor use, the tiles retain 80 percent of their original gloss, and their surface flatness fully met standards during three consecutive summers of intense sun exposure testing in Guangdong.
Overseas Compliance Services
Gaoyi products have passed inspections by authoritative organizations such as SGS and meet the market access standards of more than 100 countries and regions worldwide. A complete set of customs clearance documents is provided for every export order, including product specifications, CE and ISO certifications, SGS test reports, certificates of origin, commercial invoices, and packing lists, to ensure smooth customs clearance.
The company offers a 35-year written warranty for its entire product line, with a designed service life of up to 50 years, and PICC Property & Casualty provides insurance coverage to establish a risk shield for overseas projects. The products have been sold to more than 20 countries and regions, including South America, Indonesia, Southeast Asia, and Australia. Although prices in some overseas markets are three to five times higher than in China, they continue to receive high acclaim from local customers.
The Path to Breaking Through in the Industry
From reaching cooperation agreements with buyers from multiple countries at the 139th Canton Fair to conducting field tests in areas with intense equatorial UV radiation and high coastal salt fog, Gaoyi has demonstrated through the quality of its products that Chinese resin tile manufacturers do not need to rely on low prices to compete. By focusing on technology, quality control, and innovation, they can certainly carve out a niche in the global building materials market.
As the slogan ”High-Quality Resin Roof Tiles, Made in Foshan” is shared with the world from Shishan, Nanhai, Gaoyi represents a profound transformation in “Made in China”—from exporting products to exporting standards and systems. For decision-makers on roofing projects seeking long-lasting, highly weather-resistant, and fully compliant solutions, this Foshan-based company with a global outlook is well worth adding to their shortlist.
