CENTER International Group Co., Ltd. (CENTER INT) was founded in 2001 with a registered capital of RMB 539 million. With more than 1,700 employees and 26 branches across China, of which over 30% are technical R&D professionals, the company focuses on four primary areas: building metal cladding, ecological governance, building integrated photovoltaics (BIPV), and Integrated Smart Energy.We are the first specialized company in China's building metal cladding industry to be listed on the main board of the stock exchange.

Amid the global wave of green building development, two leaders in their respective fields—CENTER INT (a pioneer in metal cladding systems) and LONGi (a global leader in building-integrated photovoltaic (BIPV) systems)—have joined hands in a powerful strategic collaboration. By integrating CENTER INT's advanced production bases and mature design-construction-management teams with LONGi's technological advantages in photovoltaic materials, photovoltaic power generation equipment, and solar power plant systems, the partnership endows building roofs with exceptional energy-saving and emission-reduction performance. Together, we are exploring new horizons in the BIPV sector and striving to build the world's leading BIPV brand.
