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.I-beam is mainly divided into ordinary I-beam, light I-beam and wide flange I-beam. According to the height ratio of flange to web, it is divided into wide, medium and narrow flange I-beams. The specifications of the first two are -, the corresponding height is -. At the same height, the light I-beam has narrow flange, thin web and light weight. Wide flange I-beam, also known as H-beam, is characterized by two parallel legs and no inclination on the inner side of the legs. It belongs to economic section steel and is rolled on four high universal mill, so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards.Las Matas de Farfan,Precautions for galvanized pipe storage Peak crackBorsa,Plan option : Martensitic chromium alloy pipe,What is the purpose of flat steelC-section steel has uniform zinc layer, smooth surface, no zinc scar, no zinc leakage and high dimensional accuracy. All surfaces are wrapped by zinc layer, and the zinc content on the surface is usually -g /? It has long service life,Las Matas de Farfan16Mn thick wall seamless pipe, corrosion resistance and durability. It is a kind of stronger protection.

Difference and application description between H-beam and I-beamIn the production process, the stainless glittering pipe is affected by the outside and product surface. Due to galvanizing, the corrosion protection is not corroded. This is the thickness of zinc, and the quality and strength of its coating depend on longevity.I-beam can only be used for beam, while H-beam can be used for load-bearing column of structure.How many?,→ compared with the concrete structure, the I-steel structure can increase the service area by %, reduce the self weight of the structure by % - %, and reduce the structural design internal force.Application characteristics of I-beam:Plan option : Martensitic chromium alloy pipe,Las Matas de FarfanHow much is 75 galvanized pipe per meter, we must use appropriate methods to carry out installation in the case of installation, so as to ensure the performance index of the data. Generally, when installing alloy pipes, we will use some flanges and elbows to fix them, so as to ensure that the raw materials can be fixed very well. Therefore, when we carry out use, we must ensure the quality of flanges and elbows, so as to ensure the actual effect of alloy pipe assembly. If there are instrument panel components that must be assembled on the pipeline, they must be installed together.Analysis project, Small longitudinal crackWhen excavating a tunnel in a stratum where the rock is not hard and complete, it is generally necessary to excavate a diversion pit (also known as pilot hole) and set temporary support.After the passivation treatment of alloy pipe, ~ times of water cleaning, and then chromic acid closed solution shall be carried out. Chromic acid solution must be carried out h after the subsequent water cleaning of metallographic structure and austenitic alloy pipe. Chromic acid aqueous solution (mass ratio) is % ~ %, the solution temperature is ~ ℃, and the solution time is min. Then dry.Las Matas de Farfan→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.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,Because all parts of I-beam are arranged at right angles, I-beam has the advantages of strong bending resistance, simple construction, cost saving and light structural weight in all directions,Las Matas de FarfanReinforcement engineering turnover, 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.
