The invention provides parallel wide-flange-edge channel steel and a production method thereof. According to the channel steel, the specific value of the web height and the flange edge width is smaller than or equal to 1.7. The related channel steel is characterized in that the flange edge is wide, and the inner face and the outer face of the flange edge are parallel, the bearing range of the flange edge can be widened effectively, the difficulty of follow-up machining of flange edge perforating, bolt connecting, welding and the like can be reduced, and the manufacturing efficiency of the later-stage steel structure is improved. According to the production method, hole type design with side pressure is adopted in a reversible roughing mill, the wide-flange-edge channel steel can be produced with short-end-face steel blanks, casting blank applicability is widened, rolling stability of casting blanks in the reversible rough mill initial gate is improved, the production difficulty of thechannel steel is lowered, the requirement for the equipment is lowered, the production efficiency is improved, and the product pass percent is increased. Compared with a traditional channel steel production method, the production method can produce the channel steel with wider flange edge.
