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,PetionvilleHow much is a meter of 6-meter galvanized pipe, series and models are complete, which is convenient for settingKey technical characteristics of alloy pipePetionville, Seamless pipe is resistant to corrosion, acid, salt and atmospheric environment, high temperature, impact and fatigue, does not need regular maintenance, and the effective life is more than years;Plan scheme : high carbon steel with carbon content exceeding .% and alloy pipe with chromium content not less than %Saint-Marie,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, Xuanhua Iron and steel, Japan iron and steel etc.Whether I-section steel is ordinary or light, due to the relatively high and narrow section size, there is a large difference in the moment of inertia between the two main sleeves of the section. Therefore, it can only be directly used for members bent in the plane of their web or form lattice stress members. It is not suitable for axial compression members or members with bending perpendicular to the web plane, finishing roller, pre leveling unit, finishing unit and straightening unit.The electric welding reinforcement mesh can reduce the damage and consumption to the reinforcement processing process. According to statistics, after deducting the steel consumption increased by unit lapping it can also save about % of the steel. After it is transported to the site according to the construction degree of the project, it can be hoisted to the working face. There is no need to set a reinforcement processing site on the site, which saves the site and increases the management level of the site. At the same time, it can also solve the problems of noise pollution caused by straightening reinforcement. Small longitudinal crackFor more, please check,Plan scheme : high carbon steel with carbon content exceeding .% and alloy pipe with chromium content not less than % Cross rolling pass system. This pass system refers to that the two open legs of the I-beam pass are not on the same side of the waist at the same time, and the waist has an included angle with the horizontal axis.After determining the reasonable pickling agent and polishing solution, it is very easy to carry out hot galvanizing for relevant alloy pipes. Use 'phosphating treatment' to degrease the pipes of electrolytic machine equipment, put them into the aqueous solution with zinc salt after pickling and passivation, connect the negative level of electrolytic machine equipment, put them into the cold-rolled steel plate in the direction corresponding to the pipes, and connect the switching power supply, If the current flows from the positive stage to the negative stage, a layer of zinc is deposited in the pipe.

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,resources,At present, there is still a big gap in the production technology of C-section steel between China and foreign countries.Galvanized pipe is a kind of light thin-walled steel pipe with hollow square section, also known as steel cold-formed profile. It is a section steel with square section shape and size, which is made of Q hot-rolled or cold-rolled strip or coil as the base material, cold bending and high-frequency welding. In addition to wall thickness thickening, the corner size and edge flatness of hot rolled extra thick wall galvanized pipe reach or even exceed the level of resistance welding cold formed galvanized pipe.When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties,The specification of pass design I-beam is expressed in cm of waist width. For example,Petionville16Mn welded pipe manufacturer, 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 ~,PetionvilleSpiral welded pipe wholesale, expressed as No. ~ No., and the inclination of inner wall of leg is : The pass system of rolled I-beam includes direct pass system, cross pass system and mixed pass system. In addition, I-beam can also adopt special rolling method. Peak crackDetermined by the shape 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 % ~ %.
