Galvanized angle steel is divided into hot-galvanized angle steel and cold-galvanized angle steel. Hot-dip galvanized angle steel is also called hot-dip galvanized angle steel or hot-dip galvanized angle steel. Cold galvanized coatings are mainly based on electrochemical principles to ensure that zinc powder is in full contact with the steel, and the electrode potential difference is generated to prevent corrosion.
Galvanized angle steel can be divided into hot-galvanized angle steel and cold-galvanized angle steel according to process classification. Common in the market is hot-dip galvanized angle steel. Cold galvanized angle steel generally requires cold plating according to user requirements. According to the side length, it can be divided into galvanized equilateral angle steel and galvanized non-equal angle steel. Hot-dip galvanizing is divided into blow plating and rack plating.
The surface quality of galvanized angle steel is specified in the standard, and generally it is required that there are no harmful defects in use, such as delamination, scarring, cracks, etc. The allowable range of the deviation of the angle steel geometry is also specified in the standard, which generally includes such items as bending, edge width, edge thickness, vertex angle, theoretical weight, etc., and stipulates that the angle steel must not have significant twist.
