A method for forming a container half () from a coated steel sheet () is provided. Because a first planar part () at an outer peripheral part of a first formed body () provided through a first drawing step is held by a blank holder () during its bending to provide an L-shaped cross-section part () in a second drawing step, no wrinkles will develop at a vertical part (). Because an unnecessary outer part () of a flange part () is cut off in a trimming step, the width of the flange part is narrowed. By virtue of the narrowed width, no wrinkles will develop during bending of the flange part.

Method of forming coated steel sheet

A method of manufacturing a wheel rim by bringing end faces of a workpiece into abutment against each other to form a hollow cylindrical body and forming a circumferential recess which is depressed from an outer circumferential wall of said hollow cylindrical body toward an inner circumferential wall thereof, including providing protrusions disposed near ends of a joined area of the hollow cylindrical body and extending in a joining direction, and then pressing the outer circumferential wall of the hollow cylindrical body to form the recess.
