The difference between H-shaped steel and I-beam
It is often asked that the shape of the I-beam is similar to that of the H-beam. How do you choose it in practical use?
Bao Chun stainless steel encyclopedia here for everyone to do a detailed answer: Many people believe that stainless steel I-beam and stainless steel H-beam is one thing, I-beam is the domestic name, H-beam is a foreign name, in fact, this recognition Knowledge is wrong. H-shaped steel and I-beam are different in shape.
I-beam, as its name suggests, is a “workâ€-shaped section steel with an inclination on the inner surface of the upper and lower flanges, generally 1:6, making the flanges thin outside and thick inside, resulting in I-beams in two The cross-sectional characteristics of the main plane are very different, and it is difficult to exert the strength characteristics just in the application. Although the stainless steel thickened I-beams have also appeared on the I-beam market, the structure of the I-beam has determined its torsional performance is short.
H-section steel is a widely used profile in today's steel construction, and it has many differences compared to I-beams. The first is the flange, and the inner surface of the flange has no inclination. The upper and lower surfaces are parallel. The section characteristics of H-shaped steel are obviously better than those of conventional I-beam, channel steel and angle steel. H-shaped steel is an economic section efficient section with a more optimized cross-sectional area distribution and a more reasonable weight-to-weight ratio. Its section is named after the English letter “Hâ€. The outer sides of the two outer edges of the H-section steel are straight and flat. This makes the H-beam welding splicing easier than the H-beam, the mechanical properties per unit weight better, can save a lot of material and construction time.
The section of the I-section is subject to a straight pressure and is resistant to pull, but the section size is too narrow for the wing to be torsion resistant. Steel H, on the other hand, has its advantages and disadvantages.
The difference between H-shaped steel and I-beam and its use description
1. The I-beams are common or lightweight. Because the cross-sectional dimensions are relatively high and narrow, the moments of inertia of the two main sleeves of the cross section are quite different. Therefore, they can only be used directly on their webs. The in-plane bent member or the lattice-formed force member. It is not appropriate to use axial compression members or members that are bent perpendicular to the plane of the web, which limits its application.
2. H-beams are highly efficient and economical profiles (others include cold-formed thin-walled steels, profiled steel plates, etc.). Due to their reasonable cross-sectional shape, they can enable steels to perform more efficiently and improve their cutting capabilities. Unlike the general I shape, the flanges of the h-beam are widened and the inner and outer surfaces are generally parallel, which facilitates the connection of high-strength bolts and other components. Its size constitutes a reasonable series, complete model, easy to design and use. (In addition to I-beams for crane beams)
3. The flanges of H-shaped steel are all of equal thickness, have a rolling section, and also have a composite section consisting of three plates welded. I-beams are rolled sections, due to poor production processes, the edge of the flange has a 1:10 slope. The rolling of H-shaped steel is different from ordinary I-beam using only a set of horizontal rollers. Because its flange is wide and has no inclination (or a small gradient), a set of vertical rollers must be added and rolled at the same time. The rolling process and equipment are more complex than ordinary rolling mills. The maximum height of rolled steel h-shaped steel that can be produced in China is 800mm, which can only exceed the welding combination section.
China's hot-rolled H-beam national standard (GB/T11263-1998) divides the h-beam into three categories: narrow flange, wide flange and steel pile. The codes are hz, hk and hu. The narrow-flange h-beam is suitable for beam or compression-bending members, while the wide-flange h-beam and h-beam are suitable for axial compression members or press-bend members. Compared with H-beams, I-beams are not as good as h-beams in terms of weight, such as w, ix, and iy.
4. The side length of I-beam is small and high, and it can only withstand the force in one direction.
5. The H-shaped steel groove is deep and thick, and can withstand forces in both directions.
6. With the development needs of steel structures, only I-beams are not acceptable. They are thickened I-beams and are used to easily destabilize load-bearing columns.
7. I-beams can only be used for beams and H-beams can be used as structural load-bearing columns.
8. H-section steel is an economical section steel with excellent section mechanical properties compared to H-shaped steel. It is named because its section has the same shape as the English letter “Hâ€. The flanges of hot-rolled H-beam are wider than I-beams, large in lateral stiffness, and strong in bending resistance. H-type steel under the same specifications is lighter than I-beam.
9. The flange of the I-beam is made by the thickness of the web and the outside is thin. The flange of the H-shaped steel is worn.
10. HW HM HN H is the general name of H-shaped steel, H-shaped steel is welded and HW HM HN is hot rolling
11. HW is H-beam height and flange width is basically the same; mainly used for reinforced concrete frame column in the steel core column, also known as the steel column; in the steel structure is mainly used for columns.
12. HM is the H-beam height and flange width ratio of 1.33 ~ ~ 1.75; mainly in the steel structure: used as a steel frame column, in the frame structure to withstand the dynamic load used as a frame beam; for example: equipment platform.
13. HN is the ratio of H-beam height and flange width greater than or equal to 2; it is mainly used for beams; the use of I-beam is equivalent to HN-type steel.

The valve is a series of gas emergency Shut Off Solenoid Valves, specially designed as gas pipe breaker for emergency use. It can be connected with gas leaking detection sensor, fire alarm circuit or other intelligent sensor modules so that on site or remote shut down on gas supply (manually or automatically) is possible, hence ensuring the safety on gas usage. The valve features an auto-close when strong vibration is detected. After close, manual operation is required to turn on the valve. This feature meets safety regulations in the event of an accident.
