As of the end of 2023, the company's rock wool production and sales volume have ranked first in the domestic industry for nine consecutive years. To date, it has provided over 3.2 million metric tons of rock wool to the building energy conservation market, serving a total of over 60,000 engineering projects.

Rock wool, a material renowned for its high energy efficiency, reliable fire safety, sound absorption and noise reduction, has been widely used in construction, industry, shipbuilding, and agriculture for nearly a century.

Committed to independent R&D and continuous innovation, the company has mastered a new generation of rock wool production technology in recent years. Equipped with advanced, large-scale rock wool production line sets, the company's single line production capacity exceeds 100,000 tons.

Simultaneously, the application of large-scale vertical melting furnaces and waste heat utilization systems on 100,000-ton large-scale rock wool production lines has enhanced melting capacity. Thermal efficiency has surpassed 42 percent, with daily raw material melting exceeding 440 tons and daily output exceeding 330 tons, making it a global leader in this regard.

It also has refined its practices in green, low-carbon, and emissions reduction as well. The company has developed a comprehensive utilization technology for solid waste generated in rock wool production. The waste edges and powder produced during the production process can be recycled after processing, achieving clean production without external emissions and without affecting product performance.

It has also constructed two large-scale electric melting furnace production lines, reducing energy consumption by 20 percent, sulfur dioxide emissions by 30 percent, and carbon emissions by 10 percent (or 4,000 tons).
