also known as steel beam

I-beam, is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape.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.Vilanova,Defect detection of seamless pipeWhat are the uses of I-beam?Tonga,Alloy tube is widely used in our daily life, which provides us with great assistance.As shown in the name, I-beam is an I-shaped section steel. The inner surface of the upper and lower flanges has an inclination, generally :, which makes the outer flange thin and the inner flange thick. Therefore, the section characteristics of I-beam in the two main planes are very different, and it is difficult to give full play to the strength characteristics in application. Although the thickened I-beam has also appeared in the I-beam market, the structure of the I-beam has determined its torsional performance.When selecting I-beam in structural design,VilanovaPrice of 6 m 6 min galvanized pipe, reasonable I-beam shall be selected according to its mechanical properties, weldability and structural size.

Due to the unique performance of I-beam, I-beam has successfully solved the problem of serious equipment wear in many industries. It has a thick and dense pure zinc layer covered on the steel surface, which can prevent the steel substrate from touching with any corrosion solution and maintain the steel substrate from corrosion. In general atmosphere, the surface of zinc layer forms a thin and dense zinc oxide layer, which is difficult to dissolve in water so it plays a certain maintenance effect on steel matrix. If zinc oxide and other components in the atmosphere form insoluble zinc salts, the anti-corrosion effect is more ideal.I-beam can only be used for beam, while H-beam can be used for load-bearing column of structure.retailer,The core of C-section steel is the structural system of braced frame. More than half of such senior managers in China are the former. Unfavorable to earthquake resistance. Hydraulic power, and the power is large, generally about KW, which is similar to the plate shearing and bending machine. The general control process is complex, and PLC control is mostly used.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.Because all parts of I-beam are arranged at right angles,VilanovaHow to learn steel bar turning, cost saving and light structural weight in all directions simple construction, and has been widely used. The inner and outer sides of the flange of the I-beam are parallel or close to parallel, and the end of the flange is at a right angle, so it is named parallel flange I-beam. The web thickness of I-beam is smaller than that of ordinary I-beam with the same height of web, and the flange width is larger than that of ordinary I-beam with the same height of web, so it is also named wide edge I-beam.

The sodium cyanide passivation treatment of alloy pipe can be divided into four categories. Before passivation treatment, the surface of alloy pipe shall be clear of oil stains, pickled and passivated. Passivation treatment can be carried out only after the surface is cleaned,VilanovaGh4037 alloy pipe, and the workpiece of alloy pipe products can be infiltrated into aqueous solution. The passivation treatment of the alloy tube in sodium cyanide transforms the surface layer into a very thin passivation treatment film, which determines that the color of the surface layer has no change before and after passivation treatment, and the reproducibility of the solution is good.consumption,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. The rapid popularization and application of cold drawn ribbed bars and hot rolled grade III bars in China provides a good material basis for the development of welded mesh. The formal implementation of welding net product standards and application procedures has played a positive role in product quality and accelerating popularization and application.Whether I-section steel is ordinary or light, the moment of inertia of the two main axes of the section is quite different, so it can only be directly used for members bent in the plane of their web or form lattice stressed members. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which makes it very limited in the scope of application. I-beam is widely used in buildings or other metal structures.Vilanova, The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard. Frame line crackSo why is the alloy pipe easy to rust after being pickled and passivated by the software?
