What is the difference between galvanized steel bar and ordinary angle iron?

Answer:

Plain angle ironThe surface quality of ordinary angle iron is stipulated in the standard, and no harmful defects such as layering, scab and cracks are required.The allowable range of the geometric deviation of the angle iron is also stipulated in the standard. The bending angle, the width of the edge, the edge thickness, the vertex angle and the theoretical weight are generally included, and the angle steel must not be significantly reversed.Angle steel is a kind of carbon structural steel for construction. It is a simple section steel, mainly used in the frame of metal component and workshop. In use, better weldability, plastic deformation and mechanical strength are required. The raw steel billet for producing angle steel is low carbon square billet, and the finished product angle iron is made by hot rolling, normalizing or hot rolling.
Durable: galvanized steel with surface gloss, zinc layer uniform, no plating leakage, without drip, strong adhesion characteristics, strong corrosion resistance, in a suburban environment, galvanized thickness standard can be maintained for more than 50 years without repair; in urban areas or coastal areas, the standard hot galvanized layer it can be maintained for 20 years without repair;
Low handling costs: the cost of hot dip galvanizing is lower than that of other paint coatings;
Galvanized angle iron is divided into hot galvanized steel angle and cold galvanized steel angle. Galvanized steel galvanized or hot-dip galvanized steel angle is also called. Cold galvanized coating mainly through the electrochemical principle to ensure full contact between zinc powder and steel, resulting in electrode potential difference for corrosion protection.
