The "DI-type Space Net Construction Method" is a large-span structural steel method that consists of a roof made solely of steel frames assembled in a lattice pattern by sandwiching square pipes between octagonal plates and welding them together. This method is expected to provide excellent seismic resistance, economic benefits, and reduced construction time, and it has many achievements in facilities such as gymnasiums where "columns cannot be erected and large open spaces are required." Please feel free to contact us if you have any inquiries. 【Main Features】 ■ A highly aesthetic diagonal lattice design that does not require a ceiling ■ Long-standing track record and outstanding seismic strength, with high precision, low cost, and a cooperative system with local areas due to factory unit production ■ Collaboration with agents and partner factories in various regions, enabling construction by providing guidance on manufacturing and construction at local factories *For more details, please download the PDF or feel free to contact us.
