1.C型钢

1. C-shaped steel

都是经热卷板冷弯加工，由C型钢成型机自动加工而成的。壁薄自重轻，截面性能优良，强度高，与传统槽钢相比，同等强度可节约材料30%。

They are all processed by hot coil and cold bending, and are automatically processed by C-shaped steel forming machine. With thin wall and light weight, excellent section performance and high strength, the same strength can save 30% of material compared with traditional channel steel.

C型钢檩条按高度不同分为80、100、120、140、160五种规格，长度可以根据工程设计而确定，但考虑到运输和安装等条件，全长一般不超过12米。C型钢广泛应用于钢结构建筑的檩条，墙梁，也可自行组合成轻量型屋架、托架等建筑构件。此外，还可用于机械轻工制造中的柱、梁和臂等。

C-shaped steel purlins are divided into five specifications according to their height: 80, 100, 120, 140 and 160. The length can be determined according to the engineering design, but considering the conditions of transportation and installation, the total length is generally not more than 12 meters. C-shaped steel is widely used in purlins and wall beams of steel structures, and can also be assembled into lightweight roof trusses, brackets and other building components. In addition, it can also be used for columns, beams and arms in mechanical light industry manufacturing.

2.工型钢

2. I-shaped steel

称钢梁，是截面为工字形的长条钢材。其规格以腰高（h）*腿宽（b）*腰厚（d）的毫米数表示，如“工160*88*6”，即表示腰高160毫米，腿宽88毫米，腰厚6毫米的工型钢。工字钢分普通工字钢、轻型工字钢和H型钢三种。

It is called steel beam, which is a long strip of steel with I-shaped section. Its specification is expressed in millimeters of waist height (h) * leg width (b) * waist thickness (d). For example, "I 160 * 88 * 6" means I steel with waist height of 160 mm, leg width of 88 mm and waist thickness of 6 mm. I-beam is divided into ordinary I-beam, light I-beam and H-beam.

普通工型钢和轻型工型钢的翼缘由根部向边上逐渐变薄的，有一定角度。由于它们截面尺寸相对较高、较窄，故对截面两个主袖的惯性矩相差较大，因此，一般仅用于在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采用，这是其在应用范围上有着很大的局限。

The flange of ordinary I section steel and light I section steel gradually thins from the root to the edge, with a certain angle. Because their section size is relatively high and narrow, the moment of inertia of the two main sleeves of the section is relatively different. Therefore, it is generally only used for members bent in the web plane or to form a lattice load-bearing member. It is not used for axial compression members or members with bending perpendicular to the plane of the web, which is a great limitation in its application.

济南型钢厂家提醒，工字钢广泛用于各种建筑结构、桥梁、车辆、支架、机械等。

Jinan section steel manufacturer reminded that I-beam is widely used in various building structures, bridges, vehicles, supports, machinery, etc.

3.H型钢

3. H-shaped steel

是由工字型钢优化发展而成的一种断面力学性能更为优良的经济型断面钢材尤其断面与英文字母“H”相同而得名。H型钢分为、宽翼缘型钢（HW）、中翼缘H型钢(HM)、窄翼缘H型钢（HN）、薄壁H钢（HT）、H型钢（HU）。

It is a kind of economical section steel with better section mechanical properties, which is optimized and developed from I-section steel, especially the section is the same as the English letter "H". H-shaped steel is divided into, wide flange H-shaped steel (HW), middle flange H-shaped steel (HM), narrow flange H-shaped steel (HN), thin wall H-shaped steel (HT) and H-shaped steel (HU).

H型钢是一种新型经济建筑用钢。H型钢截面形状经济合理，力学性能好，轧制时截面上各点延伸较均匀、内应力小，与普通工字钢比较，具有截面模数大、重量轻、节省金属的优点，可使建筑结构减轻30-40%；又因其腿内外侧平行，腿端是直角，拼装组合成构件，可节约焊接、铆接工作量达25%。常用于承载能力大、截面稳定性好的大型建筑中的支架、基础桩等。

H-shaped steel is a new type of economical construction steel. The section shape of H-shaped steel is economical and reasonable, and its mechanical properties are good. When rolling, the extension of each point on the section is relatively uniform, and the internal stress is small. Compared with ordinary I-shaped steel, it has the advantages of large section modulus, light weight, and metal saving, which can reduce the building structure by 30-40%; Because the inner and outer sides of its legs are parallel, and the leg ends are right angles, it can be assembled into components, which can save up to 25% of the welding and riveting workload. It is often used for support and foundation pile in large buildings with large bearing capacity and good section stability.
