标题: 磨砂机械配件用途角钢镀锌冲孔角铁20*20等边三角钢非标定做

角钢是金属结构中最为重要的基本构件，可与各种型钢或钢板配合联结制作各种结构材料如桥梁、造船、储罐、石油井架等独立构件。

值得注意的是，角钢与被加固构件无论是共同承载，还是按刚度分配承受部分荷载，其所起到的作用与一般钢结构并无实质性差别。

角钢分等边角钢和不等边角钢两类，用号码数字或两边宽度x雎度的毫米数表示。等边角钢的号码数字指：边宽毫米数的十分之一，

不等边角钢的号码数字指：长边宽/短边宽毫米数的十分之一。角钢号码数字中不分a、b、c,不同厚度者常直接写出：

两边宽（长x短）x厚的规格。等边角钢产品自2〜20号，不等边角钢产品自25/1.6〜20/12.5号，通常长度二者均为3〜19米。

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。

Angle steel is the most important basic component in metal structure,

which can be combined with various steel or steel plates to make various structural materials such as bridge, shipbuilding, storage tank,

oil rick and other independent components.It is worth noting that whether the corner steel and the reinforced components bear the load together,

there is no substantial difference from the general steel structure.Angle steel is divided into two categories of equal angle steel and unequal angle steel,

indicated by the number number or the mm of width x Ju degree on both sides.The number of equal edge steel refers to one tenth of the width of mm,

and the number of unequal edge steel refers to one tenth of long width / short width of mm.Angle steel number number do not divide a, b, c,

different thickness people often directly write out: both sides wide (long x short) x thick specifications.Equicorner steel products from 220,

unequal corner steel products from 25 / 1.620 / 12.5, usually the length of 319 meters.

The test items of assessing angle steel performance are mainly tensile test and bending test.The indicators include yield point, tensile strength,

elongation rate and bending qualification.
