Tsuzuki Co., Ltd. Company Information

One-stop support for various aluminum interior and exterior building materials. Enhancing the richness and comfort of people's lives through the exterior walls of all types of buildings.

Since its founding in 1970 (established in 1972), Tsuzuki has expanded its business from product development as a manufacturer of aluminum interior and exterior building materials, primarily for buildings, to a one-stop service that encompasses manufacturing, sales, design, and construction. The aluminum building materials produced include handrails, decorative panels, canopies, and louvers, which beautifully adorn urban structures. In addition to the "aluminum building materials business," the company is also advancing initiatives in the "external insulation business" and the "renovation and renewal business for apartments and buildings." To respond to the changing needs of the times, Tsuzuki underwent an internal company split in February 2021, establishing a composite building materials company responsible for new and derivative businesses related to aluminum building materials, including the external insulation wall business, which is part of its CO2 reduction efforts. The company is also pursuing corporate growth and social contribution through composite building materials businesses that combine previously incompatible construction materials, such as aluminum and tiles, offering a different approach from the aluminum building materials business. As a company that can contribute to various fields of society, Tsuzuki Co., Ltd. will continue to challenge new possibilities.
