In the resin roofing tile industry—a sector characterized by ”low barriers to entry and intense competition”—what does it mean to be selected as a designated supplier by a Hong Kong-listed company?
This means that every aspect of your quality control, production capacity, and delivery times must withstand audit-level scrutiny by a publicly traded company.
Guangdong Gaoyi Building Materials is the company that made it through this hurdle.
Behind every supply certificate lies three key strengths
Guangdong Gaoyi Building Materials isDesignated Supplier of Henan Heart-to-Heart Chemical Industry Group Co., Ltd. (01866.HK). Heart-to-Heart Group is a major domestic chemical company with extremely rigorous supplier qualification processes, involving multiple layers of screening—from qualifications and production capacity to quality control systems. Being designated as one of its suppliers is, in itself, a highly prestigious endorsement within the industry.
But this is just the tip of the iceberg when it comes to Gao Yi's hard power.
First Level of Quality: We use only virgin materials and never use recycled materials. Against the backdrop of an industry-wide practice of using recycled materials to cut costs, Gaoyi exclusively uses brand-new raw materials from Fortune 500 suppliers such as Zhongtai Chemical and KANEKA. This is not just a slogan—it is an ironclad rule enshrined in our supply chain management system.
Second Strength: Comprehensive international certifications. The products have been tested and certified by SGS (Swiss General Notary Office), and their environmental performance, physical properties, and weather resistance all meet internationally leading standards. They have also obtained ISO 9001 quality management system certification, and all products are insured by PICC.
The third layer of difficulty: significant technical barriers. Having fully adopted European plastic roofing tile manufacturing processes developed over four decades, the company has obtained a total of 25 patents and served as a key contributor to the formulation of the *Standard for Synthetic Resin Roofing Tiles* and the *Standard for PVC Roofing Tiles*. Transforming from a product manufacturer into a standard-setter for the industry—that is what true ”strength” is all about.
From two production lines to an annual output of 60,000 metric tons—it wasn’t just luck
When Gao Yi was first established, it had only two production lines; today, it has grown to haveA 30,000-square-meter production facility, 15 fully automated production lines, and an annual production capacity exceeding 60,000 metric tonsa modern enterprise that has established overseas bases in Vietnam and Indonesia, with products exported to more than 20 countries worldwide.

What’s more, inTibet, XinjiangIn projects involving extreme climatic conditions at high altitudes, Gaoyi products have performed exceptionally well—the intense UV radiation, extreme temperature fluctuations, and wind and sand erosion found on the plateau pose the most severe tests of a building material’s weather resistance.
If you can hold your own on the snow-covered plateau, what other environment could possibly be too harsh for you?
National High-Tech Enterprise, Provincial “Specialized, Refined, Unique, and Innovative” Enterprise, and No. 1 on the 2026 Top 10 Resin Roof Tile Brands list—each of these designations is a testament to our strength.
Just how reliable are the resin tile manufacturers that supply Heart-to-Heart Group?
The answer is simple:Our strength lies in the fact that every tile is made from brand-new materials; our strength lies in our willingness to help set every standard; and our strength lies in our ability to withstand the test of every extreme environment.
This isn’t a company that got its start through marketing; it’s a company that has been built, tile by tile, on the foundation of quality.
