This disclosure shows a machine for bending and/or twisting a beam. The machine has a frame with a guide for the beam at each end. A twisting device in the form of a rotatable drum is supported on the frame and clamped to the beam and a calibrated scale is fixed to the frame to measure the amount of twist. A carriage is movably supported on the machine frame and can be clamped to the beam to advance the beam along the frame and to bend it.
