镀锌角钢理论重量.docx

1、镀锌角钢理论重量镀锌角钢理论重量表热镀锌角钢俗称角铁，是两边互相垂直成角形的长条钢材。有等边角钢和不等边角钢之分。 等边角钢的 两个边宽相等。热镀锌角钢规格以边宽边宽边厚的毫米数表示。如 “30303” ，即表示边宽为 30 毫米、边厚为3 毫米的等边角钢。也可用型号表示，型号是边宽的厘米数，如3#。型号不表示同一型号中不同边厚的尺寸。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# 镀锌角钢重量的计算方法： 每米重量 =0.00785*（边宽+边宽-边厚）*边厚 角钢规格 每米 20*20*3 0.889kg 25*25*3 1.45
