一、前言 H型钢产品有很多规格,在日本工业标准规格里有33个系列,在美国材料检验协会标准里有44个系列,合计77个系列。各系列是由腹板厚和翼缘厚不同的数种规格组成的。假如用这种厚度尺寸表示,在日本工业标准里就有67种,没有标准化的板厚尺寸有189种规格,在美国材料检验协会标准里有187种规格,合计443种规格。在这个数字基础上再加上各种材质,H型钢的品种繁多。
I. Introduction H-beam products have many specifications, there are 33 series in the Japanese industry standard specifications, in the American Society for Testing Materials standard 44 series, a total of 77 series. The series is composed of web thickness and flange thickness of several different specifications. If the thickness of the said size, there are 67 kinds of industrial standards in Japan, there is no standard size of 189 kinds of board thickness specifications, the American Society for Testing Materials standard 187 kinds of specifications, a total of 443 kinds of specifications. On the basis of this figure plus a variety of materials, H-beam variety.
