1、 Ordinary angle steel
Generally speaking, ordinary angle steel refers to the angle steel without other processing after direct hot rolling. The specification of angle steel usually has specified standards, which generally requires that there shall be no problems and defects in use, such as delamination, crack, etc.
Angle steel belongs to carbon structural steel for construction. It is a section steel with simple section. It is mainly used for metal components and plant frame. In use, it is required to have good weldability, plastic deformation performance and certain mechanical strength. The raw material billet for angle steel production is low-carbon square billet, and the finished angle steel is delivered in hot rolling forming, normalizing or hot rolling state.
2、 Galvanized steel angle
Galvanized angle steel is divided into hot-dip galvanized angle steel and cold-dip galvanized angle steel. Hot dip galvanized angle steel is also called hot dip galvanized angle steel or hot dip galvanized angle steel. The cold galvanizing coating mainly ensures the full contact between zinc powder and steel through the electrochemical principle to produce electrode potential difference for anti-corrosion.
1. Good durability: hot dip galvanized angle steel has the characteristics of surface gloss, uniform zinc layer, no missing plating, no dripping, strong adhesion and strong corrosion resistance.
2. Strong toughness of the coating: the zinc coating forms a special metallurgical structure, which can withstand mechanical damage during transportation and use;
3. Good reliability: the zinc coating and steel are metallurgically combined and become a part of the steel surface, so the coating time is more reliable;
4. More comprehensive protection: every part of the plated parts can be plated with zinc, which can be better protected even in depressions, sharp corners and hidden places.
