Our company has been involved in "steel construction" for numerous public buildings, offices, factories, and stores, supported by certified factories ranging from J grade to H grade. In heavy steel frame structures, the steel is produced in factories, and only assembly work is done on-site, making it easier to maintain consistent structural quality by managing the site welding areas. Additionally, in truss structures, the structural stability is extremely high, allowing for long spans that are impossible with other structures, such as gymnasium roofs and steel bridges. [Features] ■ Heavy steel frame structure - It is easier to maintain consistent structural quality by managing only the site welding areas. ■ Truss structure - Extremely high structural stability, achieving long spans. ■ Supported by certified factories from J grade to H grade. ■ Extensive experience in public buildings, offices, factories, and stores in both heavy and lightweight steel construction. *For more details, please feel free to contact us.
