Stainless steel structure is what people often call structural steel, such as H-shaped steel, track steel, I-beam, channel steel, angle steel, square steel, etc.
H-shaped steel is generally referred to as section steel, which is a section steel whose cross-section is shaped like an H shape. Because its cross-sectional area distribution is very optimized and the ratio of strength and weight is very reasonable, H-shaped steel is an economical and efficient steel profile that is preferred in structural construction. If you observe the section steel carefully, you will find that all parts of the section steel are formed at right angles. This allows the section steel to have strong bending and torsion resistance in both directions. Due to its simple structure, it is easy to produce and install. , and its specific gravity is light, so it has been widely used in industry. Not only that, it is also widely used in commercial buildings. Section steel is generally used in places such as columns and supports that are subject to a lot of vertical force.
As the name suggests, track steel is the track steel used by trains, subways and other transportation vehicles. Its shape is wide at the bottom and narrow at the top to increase stability and facilitate fixation. The type of track steel is usually distinguished by kilograms per meter. Track steel is divided into Steel for heavy rail tracks and steel for light rail tracks. Its cross-sectional shape is a bit like the character “work” in block script calligraphy, but the upper horizontal line of this “I” character is much shorter than the lower horizontal line, and they are distributed from the middle to both ends.
The shape of the I-beam cross section is a complete I-beam, so it is named I-beam. Moreover, the flange of the I-beam gradually becomes thinner from the root to the edge, thus forming a certain angle. The models of ordinary I-beam and light I-beam are expressed by multiplying the waist height by the leg width and then multiplying by the waist thickness. I-beams can also be represented by models, such as 16#, 20#, and 25# I-beams, which means that the waist heights of I-beams are 160mm, 200mm, and 250mm respectively. However, I-beams with the same waist height may have flanges. Different but indistinguishable, the country stipulates that the different thicknesses of the flanges are represented by adding a, b, and c after the model number. I-beams are generally used in bridges, crane rails, beams and other places subject to large shear forces.
The cross-sectional shape of the channel steel is like one half of a mouth, which looks very much like the original pig trough. Don’t underestimate this channel steel, it has many functions! Channel steel can be used to fix section steel, or section steel to section steel, section steel to I-beam, or I-beam to I-beam. And when making air ducts, it can be used to fix and support the air ducts or as reinforcements, etc. Because the quality of channel steel is relatively light among structural steels, its production cost is low, and it is widely used, it has always been a favorite in industry.
Angle steel, as its name implies, has a right-angled cross section. However, angle steel can be divided into equilateral angle steel and unequal angle steel, so the angle steel is expressed by multiplying the angle by the amount. Angle iron, commonly known as angle iron, is often used in the production of supports for various structures, such as brackets and hangers.
Square steel is steel with a square cross-section. Square steel can be divided into seamed and seamless square steel. Seamed square steel is produced by welding of steel plates, while seamless square steel is cold drawn from seamless pipes. The mechanical properties of seamless square steel are better than those of seamed square steel, but the manufacturing cost is high.
The combination of various steel profiles has created countless industrial miracles, but these structural steels are just the tip of the iceberg in the application of stainless steel profiles.
