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 flange of H-beam is of equal thickness, 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, Carbon: the higher the carbon content, the higher the hardness of steel, also known as universal 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.Ethiopia,PalinHow much is 150 galvanized pipe 1 meter,I-beam is a long strip steel with groove section, which belongs to carbon structural steel for construction and machinery. It is a section steel with complex section, and its section shape is groove shape. China&#;s imports of I-beams are greater than its exports. The main producing areas are Tangshan Iron and steel, Baotou Iron and steel, Shangang, huangte, Maanshan Iron and steel, Xuanhua Iron and steel, Japan iron and steel, etc.Key technical characteristics of alloy pipe:H-section steel belongs to high-efficiency and economic cutting profile (other cold-formed thin-wall section steel profiled steel plate, etc.). Due to the reasonable section shape, they can make the steel give more play to its performance and improve the cutting capacity. Different from ordinary I-type, the flange of H-section steel is widened, and the inner and outer surfaces are usually parallel, so it is convenient to connect with other components with high-strength bolts. Its size composition is reasonable, series and models are complete, which is convenient for setting

The utility model has the advantages that the axial force of the roll is small the axial movement is small, and the working slope is not required,Galvanized pipe, also known as galvanized pipe,Palin45 large diameter thick wall seamless pipe, is divided into hot-dip galvanizing and electro galvanizing. The hot-dip galvanizing layer is thick,Palin42CrMo seamless pipe factory, the coating is uniform, the adhesion is strong and the service life is long. The electroplating cost is low, the surface is not smooth, and the corrosion resistance is worse than that of hot dip galvanized pipe.Stages needing attention in the production and manufacture of alloy tubesQuality improvement,Classification introductiona. In the forming process, the thick steel plate has uniform deformation, small internal stress and no scratch on the surface. The alloy pipe produced and processed has higher coordination ability in the scope of size, specification and model of diameter and wall thickness, especially in the production and manufacturing of steel structure design grade thick wall pipe, especially medium diameter small thick wall pipe which has incomparable advantages of other processing technologies, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment.

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.reform, H-section steel is an economic section steel with better mechanical properties than I-section steel. It is named because its section shape is the same as the English letter 'H'. The flange of hot rolled H-beam is wider than that of I-beam, with large lateral stiffness and strong bending resistance. Under the same specification, H-beam is lighter than I-beam.Cold.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.Palin,So why is the alloy pipe easy to rust after being pickled and passivated by the software?Key technical characteristics of alloy pipe: The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard.
