Sanan Optoelectronics Co., Ltd., as my country's leading third-generation compound semiconductor company, has industrialized bases across the country. The Hunan Sanan Semiconductor project involved in this article is Sanan's third large-scale manufacturing wafer factory, and it is also the The world's leading silicon carbide full-chain integrated manufacturing platform, the entire project is listed as one of the key projects in Hunan Province.

In the horizontal direction of the project land, a crystal growth workshop, a substrate workshop, an epitaxy workshop, a chip workshop, and a packaging and testing workshop were built in sequence. Since the semiconductor industry has very strict requirements for the construction of workshop exterior walls, corrosion resistance and safety and fire protection properties need to be taken into consideration. In many aspects, the exterior wall of this project uses the green building material of Mastercard Construction Steel - colorpod® sandwich panel. This panel has passed FM certification. High-density thermal insulation, fireproof and hydrophobic rock wool is used internally, with excellent fireproof performance. The panels are coated with PVDF to give the walls chemical resistance and weather resistance to withstand the test of weather and time.

In addition, the Colorpod® sandwich panel adopts WISKIND's new generation staggered double-support tongue and groove, and is edge-sealed with polyurethane, which brings excellent airtight, watertight and wind-resistant performance to protect the project workshop.

The color contrast between white gray and iron-green gray creates a modern visual effect and highlights the lines and volumes of the building, creating a professional, advanced and high-tech impression.

As an emerging key technology field, third-generation semiconductors are gradually becoming one of the important representatives of new productivity and playing an important role in promoting industrial innovation and technological upgrading. As the industry's leading metal enclosure manufacturer and service provider, Mastercard Construction Steel Products will also adhere to the mission of "technology and innovation empower green buildings", continue to carry out R&D innovation and process breakthroughs, and help promote the development of new quality productivity!
