PROBLEM TO BE SOLVED: To provide rolling equipment for a T section which hardly causes bending, twisting and toppling of a flange of a base stock in rolling. SOLUTION: The equipment for rolling a T section comprises a rough shaping mill 1, a rough universal mill 2, an edger mill 3 and a finishing universal mill 4 which are successively arranged from the upstream side toward the downstream side of a rolling direction and produces a T section product 10 by hot-rolling a steel base stock 10' having a nearly T-shaped cross section. In the respective vicinity portions on the upstream side and the respective vicinity portions on the downstream side of the rough universal mill 2, the edger mill 3 and the finishing universal mill 4, flange guides 5A, 5B and web guides 6A, 6B for guiding the steel base stock 10' into the respective mills 2, 3 and 4 and for suppressing the abnormal deformation of the steel base stock 10' are installed. With these guides 5A, 5B, 6A and 6B, the bending and twisting of the steel base stock 10' and toppling of the flanges 12' at the longitudinal-direction tail end of the steel base stock 10' is suppressed.
