EXTRUDED STRUCTURAL ANGLE

摘要

PROBLEM TO BE SOLVED: To provide an extruded structural angle capable of preventing the occurrence of torsion when extrusion molding is done and measuring a degree of torsion simply after molding. SOLUTION: Two flat faces 10a which have substantially circular cross section and are mutually parallel with outer peripheral faces are formed. Both side fringes of both flat faces 10a are mutually connected through a partial cylindrical face 10b having the same curvature.
