Overview and type standards for No. 8 I-beams
1. Overview. No. 8 I-beam is a commonly used section steel, also known as 80 I-beam, which belongs to the light I-beam in the national standard. Its cross-sectional shape resembles the Chinese character "工", hence the name I-beam. No. 8 I-beam is widely used in construction, bridges, tunnels and other projects as the main load-bearing structural component.
The advantages of No. 8 I-beam are its large cross-sectional area, strong bearing capacity, and good flexural strength and stiffness. In addition, the manufacturing process of No. 8 I-beam is mature and easy to process and install, so it has been widely used in various projects.
Second, the model standard.
1.Size standard.
The cross-sectional height of the No. 8 I-beam is 80mm and the cross-sectional width is 43mm. It has a large cross-sectional area and is suitable for bearing large loads.
2.Material standards.
No. 8 I-beams are usually made of low-carbon steel or low-alloy steel, which has good plasticity and toughness. At the same time, in order to improve its corrosion resistance, surface treatment, such as galvanizing, painting, etc., is usually carried out.
3.Manufacturing standards.
The manufacturing of No. 8 I-beam needs to meet national standards, and its dimensional accuracy and shape tolerances need to meet relevant regulations. In addition, in order to ensure its quality and safety performance, it also needs to be rigorously inspected and tested.
4.Apply standards.
In construction, bridges, tunnels and other projects, the application of No. 8 I-beam needs to be selected and designed according to engineering requirements. Its load-bearing capacity, flexural strength and stiffness need to be calculated and analyzed on a case-by-case basis to ensure that it meets the engineering requirements. At the same time, during installation and use, it is also necessary to comply with relevant norms and standards to ensure its safety and stability.
In a word, No. 8 I-beam, as a commonly used lightweight I-beam, has a wide range of application prospects. Understanding its overview and type criteria helps to better understand and apply this steel section.
