Appearance Quality Of Galvanized Angle Steel

The surface quality of angle steel is specified in the standard, and it is generally required that there should be no harmful defects in use, such as layering, scarring, cracks, etc.
The allowable range of geometric deviation of angle steel is also specified in the standard, generally including bending degree, edge width, edge thickness, top angle, theoretical weight, etc., and it is stipulated that the angle steel shall not have significant torsion.
