1.C型鋼

1. C-shaped steel

都是經熱卷板冷彎加工，由C型鋼成型機自動加工而成的。壁薄自重輕，截面性能優良，強度高，與傳統槽鋼相比，同等強度可節約材料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型鋼檁條按高度不同分為80、100、120、140、160五種規格，長度可以根據工程設計而確定，但考慮到運輸和安裝等條件，全長一般不超過12米。C型鋼廣泛應用于鋼結構建筑的檁條，墻梁，也可自行組合成輕量型屋架、托架等建筑構件。此外，還可用于機械輕工制造中的柱、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.工型鋼

2. I-shaped steel

稱鋼梁，是截面為工字形的長條鋼材。其規格以腰高（h）*腿寬（b）*腰厚（d）的毫米數表示，如“工160*88*6”，即表示腰高160毫米，腿寬88毫米，腰厚6毫米的工型鋼。工字鋼分普通工字鋼、輕型工字鋼和H型鋼三種。

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.

普通工型鋼和輕型工型鋼的翼緣由根部向邊上逐漸變薄的，有一定角度。由于它們截面尺寸相對較高、較窄，故對截面兩個主袖的慣性矩相差較大，因此，一般僅用于在腹板平面內受彎的構件或將其組成格構式受力構件。對軸心受壓構件或在垂直于腹板平面還有彎曲的構件均不采用，這是其在應用范圍上有著很大的局限。

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.

濟南型鋼廠家提醒，工字鋼廣泛用于各種建筑結構、橋梁、車輛、支架、機械等。

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

3.H型鋼

3. H-shaped steel

是由工字型鋼優化發展而成的一種斷面力學性能更為優良的經濟型斷面鋼材尤其斷面與英文字母“H”相同而得名。H型鋼分為、寬翼緣型鋼（HW）、中翼緣H型鋼(HM)、窄翼緣H型鋼（HN）、薄壁H鋼（HT）、H型鋼（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型鋼是一種新型經濟建筑用鋼。H型鋼截面形狀經濟合理，力學性能好，軋制時截面上各點延伸較均勻、內應力小，與普通工字鋼比較，具有截面模數大、重量輕、節省金屬的優點，可使建筑結構減輕30-40%；又因其腿內外側平行，腿端是直角，拼裝組合成構件，可節約焊接、鉚接工作量達25%。常用于承載能力大、截面穩定性好的大型建筑中的支架、基礎樁等。

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.
