The invention provides high-strength special-shaped I-shaped steel and a machining method, and relates to the technical field of steel. The material of the steel is Q235 or 16Mn; the steel is of an I-shaped structure, and the four corners of the inner side of the steel are each of an arc-shaped structure. The four supporting blocks are welded to the top end face of the steel in the linear array shape, the four supporting blocks are welded to the bottom end face of the steel in the linear array shape, and the eight supporting blocks jointly form a protection structure of the top end face and the bottom end face of the steel. Through the supporting of the eight supporting blocks, the top end face or the bottom end face of the steel can be prevented from being collided with a strip-shaped wound, then the strip-shaped wound is prevented from being stressed and cracked, and the problems that firstly, when an existing device is suspended, a steel wire rope and the steel are prone to slipping, and then lifting safet
