Due to the relatively high and narrow section size of ordinary I-beam and light I-beam,Altenburg nobitz AirportHow many kilograms per meter of 100 welded pipe, the moment of inertia of the two main sleeves of the section is quite different, which makes it very limited in the scope of application. The use of I-beam shall be selected according to the requirements of design drawings.The production process can be summarized as follows: pre leveling → finishing → straightening → post leveling. Flat steel / A / B steel with width of -, thickness of -, rectangular section and slightly pure edge. Flat steel can be finished steel, or it can be used as blank for welded pipe and thin slab for laminated thin plate.Altenburg nobitz Airport, hot-dip galvanized products have been widely used in industry (such as chemical equipment, petroleum processing, metal structure, power transportation, shipbuilding, etc.), agriculture (such as sprinkler irrigation, heating room), construction (such as water and gas transportation, wire casing, scaffold, house, etc.), bridges, transportation, etc. because hot-dip galvanized productsMethods of exerting efficiency in application of C-section steelKanel,The delivery length of I-beam is divided into fixed length and double length, and the allowable difference is specified in the corresponding standards. The length selection range of domestic I-beam is divided into -, - and - according to different specification numbers. The length selection range of imported I-beam is generally -.→ compared with the concrete structure, the I-steel structure can increase the service area by %, reduce the self weight of the structure by % - %, and reduce the structural design internal force.In order to make the welded pipe have the required mechanical, physical and chemical properties, in addition to the reasonable selection of materials and forming process, heat treatment process is often necessary. In addition the mechanical, copper physical and chemical properties of aluminum, magnesium, titanium and their alloys can be changed by heat treatment to obtain different service properties.

I-beam has wide flange, thin web, many specifications and flexible use. It can save metal by % ~ % when used in various truss structures. Because the inner and outer sides of the flange are parallel and the edge end is at right angles, it is easy to assemble and combine into various components, which can save about % of the welding and riveting workload, colorful and military green, which is beautiful and generous and has certain decoration;→ compared with general section steel, it has the advantages of low cost, high precision and small residual stress. It does not need expensive welding materials and weld detection, and saves about % of the manufacturing cost of steel structure.assets,H-shaped steel groove is deep and thick, and can withstand forces in two directions.I-beam, whether ordinary or light, can only be directly used for bending members or lattice members on its Web because of its large and narrow section size and large moment of inertia difference between the two main axes on the section. It is not suitable for axial compression members and flexural members perpendicular to the web plane, so its application range is very limited. I-beams are widely used in buildings and other metal structures.The shape of small longitudinal crack on the surface of alloy pipe is less than mm The overall width is less than mm The depth is lower than .mm.

I-beam can only be used for beam, while H-beam can be used for load-bearing column of structure.Manufacturing cost,Alloy pipes can be used for heating (cooling) projects.Galvanized; hot-rolling;At the same height, light I-beam has narrower legs, thinner waist and lighter weight than ordinary I-beam. No. - is large I-beam, and No. - is medium I-beam. Imported I-beam shall be marked with actual specifications, dimensions and relevant standards.Altenburg nobitz Airport, Small longitudinal crackDue to the relatively high and narrow section size of ordinary I-beam and light I-beam the moment of inertia of the two main sleeves of the section is quite different, which makes it very limited in the scope of application. The use of I-beam shall be selected according to the requirements of design drawings.I-beam is a kind of economical section steel with better section mechanical properties. Its characteristics are as follows:
