PROBLEM TO BE SOLVED: To provide a surface treatment method capable of performing more efficiently the surface treatment of steel material.SOLUTION: First, a steel material processing part produces steel material having a predetermined shape and predetermined properties (Step S1). The steel material produced by a steel material processing part has the temperature higher than ambient temperatures, and is conveyed to a surface treatment part before the temperature is cooled to ambient temperatures. When the steel material is conveyed, the surface treatment part performs the surface treatment for the steel material of the temperature higher than ambient temperatures (Step S2). |
