METHOD FOR MANUFACTURING L-SHAPED SQUARE PIPE, DEVICE FOR MANUFACTURING L-SHAPED SQUARE PIPE, AND L-SHAPED SQUARE PIPE
Provided is a method for manufacturing an L-shaped square pipe that ensures adequate strength even without welding, a device for manufacturing the L-shaped square pipe, and the L-shaped square pipe. Provided is a method for manufacturing an L-shaped square pipe, comprising: a groove section forming step for forming a groove section by pressing one surface of a square steel pipe, along the shorter direction of the one surface, towards another surface positioned on the reverse side of the one surface; and a bending step for bending the square pipe so that the sides of the first surface sandwiching the groove section approach each other.
