1. Ordinary angle steel

Ordinary angle steel mainly refers to angle steel that is directly hot-rolled without any processing. The surface quality of angle steel is stipulated in the standard, and it is generally required that there should be no defects harmful to use, such as scarring, delamination, cracks, etc.

Angle steel is a carbon structural steel used in construction. It is a simple cross-section steel material. It is mainly used for metal components and factory building frames. It requires good weldability, plastic deformation performance and certain mechanical strength during use. The raw material billet for the production of angle steel is low carbon square steel billet, and the finished angle steel is delivered in a hot-rolled, normalized or hot-rolled state.

2. Galvanized steel

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. Cold galvanized paint mainly uses electrochemical principles to ensure full contact between zinc powder and steel, generating an electrode potential difference for anti-corrosion.

Advantage:

1. Durable: Hot-dip galvanized angle steel has the characteristics of surface gloss, uniform zinc layer, no leakage, no dripping, strong adhesion and strong corrosion resistance.

2. The coating has strong toughness: The zinc coating forms a special metallurgical structure, which can withstand mechanical damage during transportation and use;

3. Good reliability: The galvanized layer and the steel are metallurgically bonded and become part of the steel surface, so the durability of the coating is relatively reliable;

4. Comprehensive protection: Every part of the plated parts can be plated with zinc, and even recesses, sharp corners and hidden places can be fully protected.
