The specification of pass design I-beam is expressed in cm of waist width. For example, the waist width of No. I-beam is. The types of I-beam include hot-rolled ordinary I-beam, light I-beam and wide parallel leg I-beam (H-beam). The waist width of hot-rolled ordinary I-beam in China is ~, expressed as No. ~ No., and the inclination of inner wall of leg is : The pass system of rolled I-beam includes direct pass system,GuazarInconel 601 alloy pipe, cross pass system and mixed pass system. In addition I-beam can also adopt special rolling method.It is widely used in various fields of national economic construction, such as buildings, bridges, power stations, oil drilling platforms, vehicles, highways, subways,GuazarAlloy pipe, steel structure plants and large warehousesGuazar, Because zinc has excellent ductility and its alloy layer is firmly attached to the steel base, hot-plated parts can be formed by cold stamping, rolling, bending and so on without damaging the coating; Hot hole breaking cold rolling method. This method is dominated by expansion and expands vertical sliding and skew rolling. The former one is mainly cold rolling by relatively limited mandrel mill, cold rolling by few station mandrel mill, cold rolling by three high limited mandrel mill and cold rolling by fluctuating mandrel mill. In this way, the advantages of high efficiency, low metal material consumption, excellent product quality and excellent automatic control system are more and more widely used. The competitive advantage of the latter one is low cost and short whole process. It is suitable for the processing and manufacturing of CrMoG alloy pipes with large quantities, small types, multi specifications and high precision. Therefore, it is widely usedSheila,I-beamb. The professional two-sided arc welding processing technology can complete the electric welding at a good position, welding deviation and incomplete penetration, which provides us with great assistance.

However, what we need to do now is to improve the production technology level of China&#;s production process of C-section steel, and step up the formulation of relevant industry standards and inspection standards. C-section steel manufacturers should keep close contact with truck manufacturers and communicate more. In this way, it is more conducive for C-section steel manufacturers to produce C-section steel products suitable for truck industry.Are there many welded types of mesh produced? According to the welding type and overall improvement the difference between the reinforcement mesh and the welded mesh is not particularly large. It is still due to the scattered quality of the southern city. From the perspective of development to the longitudinal and transverse interleaving devices of the reinforcement mesh, the bound or welded mesh has better application quality.After isothermal quenching treatment, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment.Good reputation,Alloy pipes are widely used in building materials, and the test standards of alloy pipes are also different. Alloy pipe has high hardness and can be used at many levels, most of which is prestressed reinforcement. Where plastic deformation is not specified but compressive strength is specified, including rolling section and combined section composed of three plates welded. All I-beams are rolled sections. Due to poor production technology, the inner edge of the flange has a slope of : The rolling of H-beam is different from that of ordinary I-beam. Only one set of horizontal rolls is used. Because its flange is wide and has no inclination (or the inclination is very small), a group of vertical rolls must be added for rolling at the same time. Therefore, its rolling process and equipment are more complex than ordinary rolling mills. The maximum height of rolled H-section steel that can be produced in China is mm, which exceeds the welded composite section.Methods of exerting efficiency in application of C-section steel

According to the national standard of hot rolled H-section steel in China (GB / t-, H-section steel is divided into narrow flange wide flange and steel pile, whose codes are Hz, HK and Hu respectively. Narrow flange H-section steel is suitable for beams or compression bending members, while wide flange H-section steel and H-section steel piles are suitable for axial compression members or compression bending members. Compared with H-section steel, W, IX and iy are not as good as H-section steel under the premise of equal weight.reform,When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size.Welded pipe refers to the steel pipe with joints on the surface, which is welded after the steel strip or steel plate is bent and deformed into circular, square and other shapes. The blank used for welded pipe is steel plate or steel strip. How can the steel strip or steel plate be welded together, and what are the welding skills?→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.Guazar,Advantages of using I-beam: reduce maintenance cost, reduce downtime,Guazar6. How much is a ton of galvanized pipe, improve equipment operation rate reduce wear, reduce equipment capacity and increase power consumptionI-beam is a kind of economical section steel with better section mechanical properties. Its characteristics are as follows:According to the theory of steel structure, the I-beam flange should be stressed, that is, the I-beam should be standing rather than lying down.
