We producesquare steel bar by cold drawing through square mould from hot rolled steel round bar or hot rolled square steel bar. In this way, square steel bar has precision size tolerance, better surface and sharp corner radius. Except cold drawn square steel bar, we can also produce heat treated square steel bar. For example, annealed square steel bar, qhenched and tempered Q&T square steel bar. After heat treatment, you can get the proper square bar hardness according to your end usage. For heat treated square steel bar, straightness is very important. We have fine straightening machine to do straightening to keep good straightness.
