Introduction to Rectangular Steel Pipe Structural System

The prefabricated rectangular steel pipe structural system utilizes a proprietary high-strength bolted connection method. This method achieves rigid connections between steel pipe beams and columns or between beams solely through bolts, eliminating the need for on-site welding. The system offers simple and quick installation, superior seismic performance, lightweight structural components, high construction precision, and fast construction speed. While ensuring structural strength, this connection method improves construction efficiency and reduces project costs.

This structural system has undergone four systematic tests at the Engineering Structure and New Materials Research Center of Beijing University of Civil Engineering and Architecture. These tests rigorously evaluated the performance of beam-column joints with a 4-meter span under various building forms, including load-bearing capacity, ductility, and energy dissipation.

The system has fully implemented BIM digital design, digital model simulation, and CNC machining for production, ensuring precision in both design and manufacturing.

By revolutionizing the traditional connection methods of steel structures, this system leads the global prefabricated construction industry toward new trends, making it an ideal choice for future housing solutions.
