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 and so on.
H-shaped steel is generally referred to as section steel, that is, its cross-sectional shape is like H-shaped steel. H-shaped steel is an economical and efficient steel profile that is preferred in structural construction because of its optimized cross-sectional area distribution and a very reasonable ratio of strength to weight. If you look carefully at the profiled steel, you will find that all parts of the profiled steel are formed at right angles, which can make the profiled steel have strong bending and torsion resistance in the lateral direction. Because of its simple structure, it is easy to produce and install , and the specific gravity is light, so it has been widely used in industry, not only that, but also in commercial buildings. Section steel is generally used in places such as columns and supports that are subjected to a lot of vertical force.
As the name suggests, track steel is the track steel used by trains, subways and other 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 how many 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 "工" in regular script calligraphy, but the upper side of this character is much shorter than the lower side, and it is distributed from the middle to both ends.
The shape of the section of the I-beam is a complete I-shaped, 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 model of the ordinary I-beam and light I-beam is expressed by multiplying the waist height by the leg width and multiplying by the waist thickness. I-beams can also be represented by models, such as 16#, 20#, and 25# I-beams, which mean 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, according to national regulations, add a, b, c after the model to indicate the different thickness of the flange. I-beams are generally used in places with large shear forces such as bridges, crane rails, and beams.
The cross-sectional shape of the channel steel is like a pair and a 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, and can also fix section steel and section steel, section steel and I-beam, I-beam and I-beam. And when making air ducts, it can be used for fixing and supporting air ducts or as reinforcing ribs and so on. Because the quality of channel steel is relatively light in structural steel, and the production cost is low, Yutu is widely used, so it has always been a little darling in the industry.
As the name suggests, the angle steel is that its section is a right angle style. However, angle steel can be divided into equilateral angle steel and unequal angle steel, so the method of expressing angle steel is the number of angles multiplied by the number. Angle steel, commonly known as angle iron, is often used in the support of various structures, such as the production of brackets and hangers.
Square steel is steel with a square cross section. Square steel can be divided into seamed and seamless square steel. The seamed one is welded by steel plate, while the seamless square steel is cold drawn by seamless tube. 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.
