Differences between hot rolling and cold drawn steel pipes We are often asked how hot rolling and cold drawn steel pipes differs.There are the main differences between hot rolling and cold drawn steel pipes as follow:. Cold-formed steels allow local buckling of the cross-section so that the post-buckling bearing capacity can be fully utilized;whereas hot-rolled steels do not allow local buckling of the cross-section.
