Building components are a general term for parts that fulfill a wide range of functions and designs, from the building's structure to its interior and exterior finishes, and equipment. They utilize diverse materials such as metal, resin, wood, glass, and ceramics, and are required to have high performance in areas like strength, durability, fire resistance, thermal insulation, and sound insulation. In the manufacturing industry, a consistent process is maintained from the design and development of these components through precise processing, assembly, quality control, and stable supply. In recent years, this field has seen remarkable technological innovation, including improved design efficiency through BIM/CIM integration, labor savings in on-site construction due to prefabrication, and enhanced environmental performance through the adoption of high-performance materials. Customization and technical support are also crucial services, making this a core industry that significantly impacts the quality and productivity of construction projects.
