1.C型鋼

1. C-shaped steel

都是經(jīng)熱卷板冷彎加工，由C型鋼成型機(jī)自動(dòng)加工而成的。壁薄自重輕，截面性能優(yōu)良，強(qiáng)度高，與傳統(tǒng)槽鋼相比，同等強(qiáng)度可節(jié)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(guī)格，長(zhǎng)度可以根據(jù)工程設(shè)計(jì)而確定，但考慮到運(yùn)輸和安裝等條件，全長(zhǎng)一般不超過12米。C型鋼廣泛應(yīng)用于鋼結(jié)構(gòu)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(gòu)件。此外，還可用于機(jī)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(zhǎng)條鋼材。其規(guī)格以腰高（h）*腿寬（b）*腰厚（d）的毫米數(shù)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(duì)較高、較窄，故對(duì)截面兩個(gè)主袖的慣性矩相差較大，因此，一般僅用于在腹板平面內(nèi)受彎的構(gòu)件或?qū)⑵浣M成格構(gòu)式受力構(gòu)件。對(duì)軸心受壓構(gòu)件或在垂直于腹板平面還有彎曲的構(gòu)件均不采用，這是其在應(yīng)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(jì)南型鋼廠家提醒，工字鋼廣泛用于各種建筑結(jié)構(gòu)、橋梁、車輛、支架、機(jī)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(yōu)化發(fā)展而成的一種斷面力學(xué)性能更為優(yōu)良的經(jīng)濟(jì)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(jīng)濟(jì)建筑用鋼。H型鋼截面形狀經(jīng)濟(jì)合理，力學(xué)性能好，軋制時(shí)截面上各點(diǎn)延伸較均勻、內(nèi)應(yīng)力小，與普通工字鋼比較，具有截面模數(shù)大、重量輕、節(jié)省金屬的優(yōu)點(diǎn)，可使建筑結(jié)構(gòu)減輕30-40%；又因其腿內(nèi)外側(cè)平行，腿端是直角，拼裝組合成構(gòu)件，可節(jié)約焊接、鉚接工作量達(dá)25%。常用于承載能力大、截面穩(wěn)定性好的大型建筑中的支架、基礎(chǔ)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.
