Shutter door interlocked tube rolling forming machine
Rolling shutter door interlocked tube rolling forming machine is designed to make the tubes by the interlocked types and rolling forming principle. The use of octagonal pipes or interlocked tube mainly involves fields such as construction engineering, mechanical equipment, transportation, and aerospace.
In construction projects, octagonal pipes are mainly used as protective pipes for wires and cables, as well as for drainage pipes. The design of its eight end corners makes the pipeline connection more firm and tight, while also having good compressive and tensile properties, which can effectively protect wires and cables from external damage. In addition, due to its good structural stability and ability to withstand significant pressure and weight, octagonal pipes are also commonly used as support and load-bearing components, such as in the construction of bridges, high-rise buildings, and other engineering projects.
