We produce hexagonal steel bar by cold drawing through hex mould from hot rolled steel round bar. In this way, hexagonal steel bar has precision size tolerance, better surface and sharp corner radius. Except cold drawn hexagonal steel bar, we can also produce heat treated hexagonal steel bar. For example, annealed hexagonal steel bar, qhenched and tempered Q&T hexagonal steel bar. After heat treatment, hexagonal steel bar mechanical properties will be better or higher. For heat treated hexagonal steel bar, straightness is very important. We have fine straightening machine to do straightening to keep good straightness.
