行走在濟南的大街小巷，鱗次櫛比的高樓大廈、車水馬龍的橋梁道路，時刻彰顯著這座城市的蓬勃發展。在這些宏偉建筑的背后，型鋼扮演著不可或缺的角色。它就像建筑的骨架，默默支撐起城市的天際線，為人們的生活和工作提供安全穩定的空間。?

Walking through the streets and alleys of Jinan, the towering skyscrapers and bustling bridges and roads constantly showcase the city's thriving development. Behind these magnificent buildings, steel plays an indispensable role. It is like the skeleton of a building, silently supporting the skyline of the city and providing a safe and stable space for people's lives and work. ?

型鋼的多樣類型?

Various types of steel sections

1. 工字鋼?

1. I-beam

工字鋼，因其橫截面形狀酷似漢字 “工” 而得名。它的腿部內側有一定傾斜度，上下翼緣較窄，腰部相對較厚。這種獨特的結構，讓工字鋼具有出色的抗彎強度。在濟南的大型廠房建設中，常被用作橫梁。由于跨度大，對支撐結構的抗彎性能要求高，工字鋼能夠憑借自身優勢，有效承載屋頂和設備的重量，確保廠房的穩固。?

I-shaped steel is named after its cross-sectional shape that resembles the Chinese character "gong". It has a certain inclination on the inner side of its legs, narrow upper and lower wing edges, and a relatively thick waist. This unique structure gives I-beams excellent bending strength. In the construction of large factories in Jinan, it is often used as a crossbeam. Due to the large span and high requirements for the bending resistance of the supporting structure, I-beams can effectively bear the weight of the roof and equipment, ensuring the stability of the factory building with their own advantages. ?

2. 槽鋼?

2. Channel steel

槽鋼的截面呈凹槽形，如同一個開口的矩形。它的用途十分廣泛，在濟南老舊小區改造中，常被用于搭建腳手架。因其獨特的形狀，便于與其他部件連接，不僅能快速搭建起穩定的施工平臺，還能在不同的建筑結構中，作為支撐或加固材料使用，滿足多樣化的施工需求。?

The cross-section of the channel steel is groove shaped, like an open rectangle. It has a wide range of uses and is often used to build scaffolding in the renovation of old residential areas in Jinan. Due to its unique shape, it is easy to connect with other components, not only can it quickly build a stable construction platform, but it can also be used as a support or reinforcement material in different building structures, meeting diverse construction needs. ?

3. H 型鋼?

3. H-shaped steel

H 型鋼的截面形狀類似英文字母 “H”，與工字鋼相比，它的翼緣內外側平行，截面尺寸更為合理。H 型鋼的整體性能更優，在高層建筑中應用廣泛。在濟南不斷崛起的摩天大樓中，H 型鋼憑借高強度和良好的穩定性，成為核心筒和框架結構的首選材料，有效抵抗風力和地震力對建筑的影響。?

The cross-sectional shape of H-beam is similar to the English letter "H". Compared with I-beam, its flanges are parallel on the inner and outer sides, and the cross-sectional dimensions are more reasonable. H-shaped steel has better overall performance and is widely used in high-rise buildings. Among the rising skyscrapers in Jinan, H-beams have become the preferred material for core tubes and frame structures due to their high strength and good stability, effectively resisting the impact of wind and earthquake forces on buildings. ?

4. 角鋼?

4. Angle steel

角鋼有等邊角鋼和不等邊角鋼之分，截面為直角形。別看它個頭不大，作用卻不小。在濟南家庭裝修中，角鋼常用于制作家具框架，如衣柜、書架等。它堅固耐用，能夠為家具提供穩定的支撐，同時在小型建筑的加固和連接部位，也能發揮重要作用。

Angle steel can be divided into equilateral angle steel and unequal angle steel, with a right angled cross-section. Despite its small size, its function is not insignificant. In home decoration in Jinan, angle steel is commonly used to make furniture frames, such as wardrobes, bookshelves, etc. It is sturdy and durable, providing stable support for furniture, and also plays an important role in reinforcing and connecting small buildings.
