The utility model relates to a double-arc steel section structure, in particular to a novel section structure of power transmission tower material in the process of power transmission. The section structure comprises a corner angle and limb plates at both sides, the corner angle is a reinforcing section, and the joints between the limb plates at both sides and the reinforcing section are opposite S-shaped cambered sections. By adopting the cold bending process, the scheme can produce reasonable section shapes with optimal material distribution according to requirements, the section structure of the scheme adopts a double-S radian design in combination with the advantages of the conventional hot-rolled angle iron and the cold bending process, the ratio between the free extension length and the thickness of the limb plate can be optimized according to need, the reduction of stability strength, which is caused by the strength of steel, is decreased, the strength utilization rate of member material is increased,
