Section steels, a specific type of steel material, play an important role in the fields of building and engineering. They have a specific cross-section shape and dimension. So what are the types of section steel?
The types of Section Steel
Section steel can be divided into simple section steel and complex section steel according to their different shapes. The former covers several common types of section steel, such as square steel, round steel, flat steel, and steel angle, etc. While the latter includes special-shaped steel such as I-beam, H-beam, and steel channel, etc. In addition, section steel also can be classified into ordinary section steel and high quality section steel. In ordinary section steels, I-beam, steel channel, steel angle, and round steel are common types that play an important role as supports and connections in building structures.
Introduction of common types of Section Steels
I-Beam
I-beam is a type of steel with a cross-sectional shape similar to the English letter "I" . The inner surface of the flange of I-beam is oblique. Compared with other section steels, I-beam has lighter weight, which can help to reduce structural self weight. In additions, I-beam also has good plasticity, which makes that it is easy to process and install, improving the construction efficiency.
H-Beam
H-beam is a type of high performance section steel, the top and bottom surfaces of the flange are parallel, which can effectively disperse the stress. In terms of mechanical properties, the section modulus of H-beam is large and the moment of inertia is high, so its unique section design makes H-beam has stronger load-bearing capacity under the same bearing conditions.
Steel Channel
Steel channel, due to its shape is similar to the letter "U", so it is also known as U-beam. Steel channel has excellent load-bearing capacity, enabling it to withstand large loads and stress. In additions, steel channel also has good welded performance and workability, which makes it easy to cut and bend.
Steel angle
Steel angle, also known as angle iron, is a type of long strip of steel with two sides perpendicular to each other forming an angle. Steel angle can be divided into equal steel angle and unequal steel angle according to different shapes. Both equal steel angle and unequal steel angle can either be drilled, bolted or welded to other steel structure, improving the load capacity of steel structure itself.
