Ordinary Angle:
Ordinary Angle steel mainly refers to the direct hot rolled out without any processing of Angle steel. The surface quality of Angle steel is stipulated in the standard, and it is generally required that there should be no harmful defects in use, such as scarring, stratification, cracks, etc.
The allowable range of Angle steel geometric shape deviation is also specified in the standard, generally including bending degree, side width, side thickness, apex Angle, theoretical weight and other terms, and stipulate that the Angle steel shall not have significant torsion.
Angle steel is a carbon structural steel used in construction. It is a simple section steel. It is mainly used in metal components and the frame of workshop. Good weldability, plastic deformation performance and a certain mechanical strength are required in use. The raw billet for the production of Angle steel is low carbon square billet, and the finished Angle steel is delivered in hot rolled, normalized or hot rolled state.
Galvanized Angle steel:
Galvanized Angle steel is divided into hot-dip galvanized Angle steel and cold galvanized Angle steel. Hot-dip galvanized Angle steel is also called hot-dip galvanized Angle or hot-dip galvanized Angle steel. Cold galvanized coating mainly through the electrochemical principle to ensure the full contact between zinc powder and steel, resulting in electrode potential difference for corrosion prevention. advantages
1, durable: hot dip galvanized Angle steel with surface gloss, zinc layer uniform, no leakage plating, no slip, strong adhesion, corrosion resistance, in the suburban environment, the standard hot dip galvanized rust thickness can be maintained for more than 50 years without repair; In urban or offshore areas, a standard hot-dip galvanized layer can last up to 20 years without repair;
2, the treatment cost is low: the cost of hot dip galvanized rust prevention is lower than that of other paint coatings;
3, the toughness of the coating is strong: galvanized layer forms a special metallurgical structure, this structure can withstand mechanical damage in transport and use;
4, good reliability: galvanized layer and steel is metallurgical combination, become a part of the steel surface, so the durability of the coating is more reliable;
5, save time and effort: galvanized process is faster than other coating construction method, and can avoid the time required after installation on the site;
6, comprehensive protection: every part of the plating can be coated with zinc, even in the depression, sharp corners and hidden places can be fully protected.
