The expression method is height, width, web thickness, and flange thickness. For example, section steel is expressed as height, width, web thickness, and flange thickness. The grade of wide flange section steel is or.
Advantages of hot-rolled section steel
Section steel is a new type of economical construction steel. The cross-section shape of the section steel is economical and reasonable, with good mechanical properties. During rolling, the extension of each point on the section is relatively uniform and the internal stress is small. Compared with ordinary I-beam steel, it has the advantages of large section modulus, light weight and metal saving, which can make the building structure lighter and reduce the internal stress. The inner and outer sides of the legs are parallel, and the leg ends are at right angles. They are assembled into components, which can save up to a lot of welding and riveting work. It is often used in large-scale buildings that require large interception capacity and good cross-sectional stability (such as high-rise factory buildings, etc., as well as bridges, ships, lifting and transportation machinery, equipment foundation supports, foundation piles, etc.
Section steel is mainly used in industrial plants, civil buildings, municipal buildings, etc. Engineering petroleum platform bridge flat car girder electrified railway power support steel structure bridge along the railway and other light and ultra-light steel is very suitable for container mobile homes all kinds of garages box type trains electrical support all kinds of venues small villa manufacturing industry.
Hot-rolled The section steel reasonably distributes the aspect ratio of the cross-section size according to different uses, and has excellent mechanical properties and superior usability.
