I-beam is divided into ordinary I-beam and light I-beam. The specification of hot rolled ordinary I-beam is -#. The specification of hot-rolled flexible I-beam supplied through agreement between the supplier and the buyer is -#. I-beam is mainly used in building structure, vehicle manufacturing, other industrial structures and fixed panels and cabinets. I-beam is often used together with I-beam.H-section steel is an economic section high-efficiency profile with more optimized section area distribution and more reasonable strength weight ratio. It is named because its section is the same as the English letter 'H'. There is no slope on the inner side of the two outer edges of H-section steel, which is straight. This makes the welding and splicing of H-section steel simpler than I-section steel, better mechanical properties per unit weight, and can save a lot of materials and construction time.Colmar,Installation of galvanized pipe and precautionsSome applications of I-beam:Karlovac, Mixed pass system. According to the characteristics of rolling mills and products in order to give full play to the advantages of their respective systems and overcome their disadvantages, mixed pass system is often adopted, that is the combination of more than two systems. For example, straight leg cross rolling pass system is adopted for finished hole and front hole of finished product, and bent leg cross rolling system is adopted for other passes; or direct rolling system is adopted for rough rolling hole and straight rolling system is adopted for the last ~ finish rolling holes Leg oblique tie hole, etc. Small longitudinal crackThe 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,ColmarHow much is DN100 galvanized pipe per meter, or it can be used as blank for welded pipe and thin slab for laminated thin plate.

Its heat sealing effect is remarkable. It can be directly buried immediately, which can not only save resources, but also reduce consumption, not occupy the natural environment but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation, prevent actual operation and maintenance, meet the requirements of thermal insulation and cold protection, reduce heating equipment, unique and convenient installation, and reduce the construction cycle time of the project. On the whole, it is more convenient to use. It can also be used for the transportation of floor heating and hot springs.Galvanized pipe can be seen from its name. It is a square pipe type. Many materials can form galvanized pipe body. It is used for what purpose and where. Most galvanized pipes are steel pipes. After unpacking, leveling, crimping and welding, they form round pipes, which are rolled into square pipes, and then cut into the required length. Generally, there are galvanized pipes in each package. In terms of spot, ranging from * * .- to * * - Galvanized pipes are divided into structural galvanized pipes, decorative galvanized pipes, architectural galvanized pipes, mechanical galvanized pipes, but also reduce consumption, not occupy the natural environment, but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation, prevent actual operation and maintenance, meet the requirements of thermal insulation and cold protection reduce heating equipment, unique and convenient installation, and reduce the construction cycle time of the project. On the whole, it is more convenient to use. It can also be used for the transportation of floor heating and hot springs.High quality brand,Alloy pipe is a very important way and type of seamless steel pipe. Its use is relatively common. It is widely used in various engineering projects, house construction and building decoration. Its fracture will always be found in the production, manufacturing and key marketing of alloy pipe, That is, many stages of production and processing are not done well. Another is that the seasoning is not enough and the proportion of chemical molecules is wrong. There are all reasons.b. The professional two-sided arc welding processing technology can complete the electric welding at a good position, which is not easy to have the disadvantages of staggered joint, welding deviation and incomplete penetration, the section modulus, moment of inertia and corresponding strength of I-beam are obviously better than those of ordinary I-beam with the same single weight. When used in metal structures with different requirements, it shows its superior performance in bearing bending moment, pressure load and eccentric load. Compared with ordinary I-beam, it can greatly improve the bearing capacity and save metal by % ~ %.original,Some applications of I-beam:During the construction of building wall, cracks and hollows show that the construction materials are unqualified, the construction at the matrix junction is not in place, and the construction personnel are poor. The external wall plastering adopts electric welding steel wire mesh, which can prevent cracking and strengthen the wall.→ I-beam can be processed into T-beam, and honeycomb beam can be combined to form various section forms, which greatly meets the needs of engineering design and manufacturing.Colmar, Peak crackPlan scheme : for high carbon steel with carbon content of more than .% and high chromium alloy pipe with chromium content of no less than %, the interval is min.Classification introduction
