镀锌角钢的热镀锌和冷镀锌的区别：热镀锌厚度和性能高于冷镀锌。热镀锌角钢的工艺流程： 角钢酸洗→水洗→浸助镀剂→干燥预热→挂镀→冷却→钝化→清洗→打磨→热镀锌。热镀锌角钢的镀锌层厚度均匀， 在30-50um之间有较大的差异，而且有很好的可靠性。冷镀锌工艺是用锌填料在被保护的表面上涂上锌填料以保护金属， 使之不受腐蚀，使之不受腐蚀，在干燥涂层中可获得含量为95%的锌填料。型号不表示同一型号中不同边角铁厚的尺寸， 因而在合同等单据上将角钢的边宽、边厚尺寸填写齐全，避免单独用型号表示。热轧等边角钢的规格为2#-20#。 角钢可按结构的不同需要组成各种不同的受力构 件，也可作构件之间的连接件。 考核角钢性能的检验项目主要为拉伸试验和弯曲试验。指标包括屈服点、抗拉强度、延伸率及弯曲合格等项。 The difference between hot galvanizing and cold galvanizing of galvanized angle steel: the thickness and performance of hot galvanizing are higher than that of cold galvanizing.Process flow of hot dip galvanized corner steel: Angle steel acid wash immersion plating agent drying preheating hanging plating cooling passivation cleaning and grinding hot dip galvanizing. The galvanized layer of hot-dip galvanized angle steel is uniform in thickness, varies greatly between 30-50um, and has good reliability. Cold galvanizing process uses a zinc filler coated with a protected surface to protect the metal from corrosion and contains 95% zinc packing in a dry coating. The model does not indicate the size of different corners in the same model, so the side width and thickness of Angle steel are fully completed in the contract documents, to avoid the model alone. The specification of hot rolled equal steel is 2 # -20 #. Angle steel can be composed of different stressed components according to the different needs of the structure, and can also be used as a connection part between the components. The test items for assessing the performance of angle steel are mainly tensile test and bending test.The indicators include yield point, tensile strength, elongation rate and bending qualification.
