邯郸双恒金属制品有限公司工字钢生产质量保证

工字型钢不论是普通型还是轻型的，由于截面尺寸均相对较高、较窄，故对截面两个主轴的惯性矩相差较大，故仅能直接用于在其腹板平面内受弯的构件或将其组成格构式受力构件。对轴心受压构件或在垂直于腹板平面还有弯曲的构件均不宜采用，这就使其在应用范围上有着很大的局限。工字钢广泛地应用于建筑或 其他金属结构。

普通工字钢，轻型工字钢，由于截面尺寸均相对较高、较窄，故对截面两个主轴的惯性矩相差较大，这就使其在应用范围上有着很大的局限。工字钢的使用应依据设计图纸的要求进行选用。

在结构设计中选用工字钢应依据其力学性能，化学性能，可焊性能，结构尺寸等选择合理的工字钢进行使用。

Handan Shuangheng metal Products Co., Ltd. I-beam Production Quality Assurance

I-shaped steel, whether ordinary or lightweight, can only be directly used for components that are bent in the plane of their web or to form lattice load-bearing components due to the relatively high and narrow cross-sectional dimensions, resulting in a significant difference in the inertia moments of the two main axes of the section. It is not suitable to use axial compression components or components with bending perpendicular to the web plane, which limits their application range. I-beams are widely used in buildings or other metal structures.

Ordinary I-beams and lightweight I-beams have significant differences in the inertia moments of the two main axes of the cross-section due to their relatively high and narrow cross-sectional dimensions, which limits their application range. The use of I-beams should be selected according to the requirements of the design drawings.

In structural design, the selection of I-beams should be based on their mechanical properties, chemical properties, weldability, structural dimensions, etc., and a reasonable selection of I-beams should be used.
