Customized solution

One-stop customized thermal insulation solutions for rock wool, glass wool pipe shells, and aluminosilicate materials.
Our company specializes in the production and supply of rock wool products, glass wool pipe shells, and aluminosilicate refractory insulation materials, with a deep focus on providing comprehensive thermal insulation and fire‑resistance solutions for the three core sectors of construction, industry, and marine applications. Tailoring our offerings to the specific temperature conditions, fire‑safety standards, operating environments, installation requirements, and acceptance criteria of each project, we address the limitations of conventional, one‑size‑fits‑all materials by delivering end‑to‑end, customized solutions that encompass material selection, bespoke specification, system‑level adaptation, coordinated installation, and seamless, one‑stop delivery. This approach precisely resolves a wide range of challenges related to thermal insulation and noise reduction, fire protection and fire resistance, as well as energy efficiency and corrosion prevention, helping to enhance quality while reducing costs across diverse engineering projects.

I. Differentiated Positioning of Three Core Product Lines Leveraging a comprehensive portfolio of thermal insulation and refractory materials, we cover the full temperature spectrum—from low to medium to ultra‑high—while ensuring complementary performance and flexible, on‑demand combinations to meet the customized requirements of diverse and complex operating conditions: - Rock wool products (boards and pipe shells): Manufactured from premium basalt raw materials, these products are Class A1 non‑combustible, with a maximum service temperature of 600°C. They offer multiple advantages, including high strength, water repellency and moisture resistance, vibration resistance, corrosion resistance, and excellent sound insulation and noise reduction. Highly versatile, they are ideally suited for building fire protection and thermal insulation, industrial medium‑ and high‑temperature pipeline and equipment insulation, as well as ship cabin and deck protection, making them a cost‑effective, core insulation solution for a wide range of engineering projects.

- Glass wool pipe shells: Featuring an ultra-fine, porous fiber structure, they offer low thermal conductivity, lightweight softness, and excellent noise‑reduction performance. With a temperature resistance of up to 400°C, they are easy to install and produce no dust. Designed for medium‑ and low‑temperature insulation, cold‑storage applications, and noise control, they are widely suited for insulating central air‑conditioning ducts, ventilation systems, data‑center equipment, and low‑temperature steam pipelines.

- Aluminum silicate fiber products (boards/tubes): Operating temperature range 600°C–1100°C; excellent chemical stability; resistant to acids and alkalis, highly resistant to high‑temperature oxidation, with low thermal capacity and outstanding resistance to high‑temperature erosion. Specifically engineered for demanding ultra‑high‑temperature industrial applications, suitable for refractory insulation in kilns, boilers, high‑temperature flue gas ducts, petrochemical high‑temperature reaction equipment, and other similar environments.
