C - section steel is reliable and stable in stress, and is resistant to impact and vibration Moreover, it has good versatility and combination, and has a variety of C-section steel and size selection to ensure its flexibilityH-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.neutral,Due to the impact of poor visual . Only through the application of mesh and the overall stiffness can we see the potential of demand. The application of steel data is a high one,neutralHow many kilograms per meter of 150 welded pipe, such as the reuse rate of mesh and reinforcement installed in the current mesh production company and the treatment of corrosion. The design strength value of circular reinforcement and the design strength value of welded reinforcement mesh. According to the equal strength substitution principle and considering comprehensive factors, the use of steel welded mesh plate can save the use of steel bars in the steel welded mesh plate factory. And the reinforcement mesh needs to be processed after it is shipped to the site, so there is no wear. The defects can be removed by grinding with sand wheel,I-beam also known as steel 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. Frame line crack Remove defective pipes within the allowable length.

I-beam can only be used for beam, while H-beam can be used for load-bearing column of structure.The preparations for the construction of high-speed reinforcement mesh include the preparation and inspection of raw materials, the inspection and acceptance of the lower layer of the pavement, and the preparation of construction equipment and engineering machinery.Ways to obtain surface compressive stress characteristics of alloy tubesoriginal,Whether I-section steel is ordinary or light, because the section size is relatively high and narrow, 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. Remove defective pipes within the allowable length. 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.

Heating surface tubes for low and medium pressure boilers (working pressure is generally not greater than MPA and working temperature is below ℃);project, 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.Galvanized pipe refers to the shape and high frequency of hollow square steel pipe welded by the back of the steel pipe during the hot rolling or cold rolling of galvanized steel plate or cold bending of galvanized steel plate, or before the galvanization of cold hollow pipe. Galvanized. Galvanized square pipe can be divided into hot galvanized pipe and cold galvanized pipe from the production process. This is because the two galvanized pipes are different, which also leads to many different physical and chemical properties.It can withstand continuous moderate impact and can provide composite plates of various thicknessesneutral,neutralHow much is the price of DN50 galvanized pipe,Whether I-section steel is ordinary or light, because the section size is relatively high and narrow, 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.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.Application characteristics of I-beam:
