普通角钢主要指的直接热轧出来没有经过任何加工的角钢。角钢表面质量在标准中有规定，一般要求不得存在使用上有害的缺陷， 如结疤、分层、裂缝等。角钢几何形状偏差的允许范围在标准中也有规定，一般包括弯曲度、边宽、边厚、顶角、理论重量等项， 并规定角钢不得有显著的扭转。角钢属建造用碳素结构钢，是简单断面的型钢钢材，主要用于金属构件及厂房的框架等。 在使用中要求有较好的可焊性、塑性变形性能及一定的机械强度。生产角钢的原料钢坯为低碳方钢坯，成品角钢为热轧成形、 正火或热轧状态交货。镀锌角钢分为热镀锌角钢和冷镀锌角钢。热镀锌角钢也叫热浸镀锌角钢或热浸锌角钢。 冷镀锌涂料主要通过电化学原理保证锌粉与钢材的充分接触，产生电极电位差来进行防腐。 Ordinary corner steel mainly refers to the direct hot rolled corner steel without any processed corner steel. The surface quality of corner steel is specified in the standard, and generally requires no harmful defects in use, such as scar formation, stratification, cracks, etc.The allowable range of geometry deviation of angle steel is also stipulated in the standard, generally including bending degree, edge width, edge thickness, top angle, theoretical weight, etc., and stipulates that angle steel shall not have significant torsion. Angle steel is a carbon structure steel for construction, is a simple section of type steel steel, mainly used for metal components and plant framework.Good soldability, plastic deformation performance and certain mechanical strength are required in use. The raw material billet for producing angle steel is low-carbon square billet, and the finished angle steel is hot rolled formed, hot or hot rolled state delivery.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 zinc angle steel. Cold galvanized coating mainly ensures the full contact between zinc powder and steel through the electrochemical principle, and produces the electrode potential difference for corrosion prevention.
