The utility model provides an edge protection device for steel structure lifting. The free edges of two outer side walls of angle steel are respectively connected with the left side and the right side of a bent plate, grooves are respectively formed in two inner side walls of the angle steel, and magnets are arranged in the grooves. Pedestals are respectively arranged at the upper end and the lower end of the angle steel, and a lifting lug is arranged on the top surface of the pedestal at the upper end of the angle steel. The edge protection device has the advantages of simple structure, convenience for use, light weight, strong practicality, wide range of application and recyclability. Welding temporary lifting points on a branch piece can be avoided, and the trouble of blanking, welding and processing the temporary lifting points is removed. The production cost is greatly reduced, the production efficiency is increased, and the construction time is saved.
