不锈钢工字钢，又称钢梁，是一种具有工字钢截面的长钢带。工字钢分为普通工字钢和轻型工字钢。它是一种工字钢。由于环境保护，唐山地区的厂家目前处于停产限产状态。因此，工字钢的价格也不确定。 工字钢无论是普通还是轻型，截面尺寸都比较高，而且比较窄，因此截面两个主轴的转动惯量差别很大。因此，工字钢只能直接用于腹板平面内弯曲的构件或承受晶格荷载的构件。轴向受压构件或垂直于腹板平面和弯曲的构件不适合使用，这限制了它们的应用。工字钢广泛应用于建筑或其它金属结构中。普通工字钢和轻型工字钢的截面尺寸都比较高和窄，因此截面上两个主套筒的惯性矩相差很大，限制了它们的应用。工字钢应按设计图纸要求选用。 在结构设计中，工字钢应根据其力学性能、化学性能、焊接性、结构尺寸等进行选择。
Stainless steel I-beams, also known as steel beams, are long steel strips with I-shaped sections. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-section shape. Due to environmental protection, manufacturers in Tangshan area are currently in a state of shutdown and production restriction. Therefore, I-beam prices are also uncertain. I-section steel, whether ordinary or light, has relatively high and narrow cross-section size, so the moment of inertia of the two main axes of the cross-section is quite different. Therefore, I-section steel can only be used directly for members bent in the web plane or for members subjected to lattice loads. Axial compression members or those that are perpendicular to the web plane and bending are not suitable for use, which limits their application. I-beam steel is widely used in buildings or other metal structures. Common I-beams and light I-beams have relatively high and narrow cross-section sizes, so the inertia moment of the two main sleeves of the cross-section is quite different, which limits their application. I-beam should be selected according to the requirements of design drawings. In structural design, I-beam should be selected according to its mechanical properties, chemical properties, weldability, structural size and so on.
