Product introduction
◆ Size, weight and tolerance:
Carbon hexagon steel bars with a distance across sides of 8mm~70mm.
Hexagonal steel bar can be composed of various stress components according to different structural needs, and can also be used as connectors between components. Carbon hexagon steel bars are widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, and warehouse shelves.
