型钢是在建筑中常被使用的一种钢材。它的截面形状十分符合力学定律，内部密度均匀，受力平衡。在与普通的工字钢比较时，它的自重虽然轻但结构却更加稳定，能使建筑在节省成本的同时达到抗震的效果。在一定的应力幅度内几乎是完全弹性的，实际受力情况与建筑力学计算的结果比较符合。

Section steel is a type of steel commonly used in construction. Its cross-sectional shape conforms very well to the laws of mechanics, with uniform internal density and balanced stress. When compared with ordinary I-beams, although their weight is light, their structure is more stable, which can achieve seismic resistance while saving costs. Within a certain stress amplitude, it is almost completely elastic, and the actual stress situation is consistent with the results of building mechanics calculations.

济南型钢主要用于工程，厂房设备，机械设备，桥梁，高速公路，民房等;机械性能和物理性能好，牢固，节约能源和环保的效果。型钢是一种经济型断面钢材，广泛用于工业、建筑、桥梁、石油钻井平台等方面。

Jinan section steel is mainly used in engineering, factory equipment, mechanical equipment, bridges, highways, residential buildings, etc; Good mechanical and physical properties, sturdy, energy-saving and environmentally friendly effects. Section steel is an economical section steel widely used in industries, buildings, bridges, oil drilling platforms, and other fields.

因为型钢强轴方向的抗侧能力非常好，所以它通常被作为是建筑的梁、柱使用，这很好的发挥了它的特性。而且根据数据显示，使用型钢建造的房屋要比其他钢材节约15%~25%的材料，并且增加了建筑的有效空间。

Due to its excellent lateral resistance in the strong axis direction, section steel is usually used as beams and columns in buildings, which fully demonstrates its characteristics. Moreover, according to data, houses built with steel profiles save 15% to 25% more materials than other types of steel, and increase the effective space of the building.

型钢可以按照生产方式分为两种，热轧型钢与焊接型钢。其中焊接型钢的生产过程就是将厚度适中的带钢截成需要的宽度，再将它们在焊接机上将边部和腰部焊接在一起。而热轧型钢的生产过程就是将带钢加热进行轧制，再进行切边、矫正。

Section steel can be divided into two types according to production methods, hot-rolled section steel and welded section steel. The production process of welded steel is to cut the strip steel with appropriate thickness into the required width, and then weld them together at the edges and waist on the welding machine. The production process of hot-rolled section steel involves heating the strip steel for rolling, then trimming and correcting it.

在轧制工艺方面型钢与普通的工字钢的差异就是工字钢能在两辊孔型中进行轧制，而型钢则需要在万能孔型中进行轧制。热轧型钢使用的是四辊万能轧制工艺，这使它在使用过程中拥有高效、低耗、低成本的优点。

The difference between section steel and ordinary I-beam in terms of rolling process is that I-beam can be rolled in a two roll pass, while section steel needs to be rolled in a universal pass. The hot-rolled section steel uses a four roll universal rolling process, which gives it the advantages of high efficiency, low consumption, and low cost during use.

热轧型钢与焊接型钢各有优点。但热轧型钢因生产工艺问题，产量要远远地低于焊接型钢且规格自由度没有焊接型钢大，所以生活中焊接型钢要更加常用一些。您有需求就来我们网站http://www.jnhxtcg.com咨询了解！

Hot rolled steel and welded steel have their own advantages. However, due to production process issues, the output of hot-rolled steel is much lower than that of welded steel, and the degree of freedom of specifications is not as large as that of welded steel, so welded steel is more commonly used in daily life.
