Appearance inspection: Check whether the surface of the galvanized square pipe is smooth and smooth, and whether there are scratches, dents, oxidation and other defects.
Dimensional inspection: Measuring the length, width, thickness, edge flatness, straight Angle and other dimensional parameters of the square tube to ensure that it meets the standard requirements.
Chemical composition inspection: The chemical composition of the hot dip galvanised square tube is analyzed by sampling to ensure that its element content meets the standard requirements.
Mechanical properties test: including elongation, yield strength, tensile strength, impact toughness and other performance indicators test to evaluate the mechanical properties of the square pipe.
Surface quality inspection: Quality assessment of the surface of the tube to check whether there is oxidation, rust, coating adhesion and other problems
