After hot-dip galvanizing of steel structure, it is equivalent to one-time annealing treatment, which can effectively improve the mechanicalof steel matrix, eliminate the stress during steel forming and welding, and is conducive to turning of steel structure.

0 Welded steel mesh is aesthetically pleasing.

eU.S.AI-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,Products Show it is divided into wide, medium and narrow flange I-beams. The specifications of the first two are -, that is, the corresponding height is -. At the same height, 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.

Are there many welded types of mesh produced? According to the welding type and overall improvement, the difference between the reinforcement mesh and the welded mesh is not particularly large. It is still due to the scattered quality of the southern city. From the perspective of development to the longitudinal and transverse interleaving devices of the reinforcement mesh, the bound or welded mesh has better application quality.

OHollickThe allowable deviation of vertical installation of galvanized pipe is mm per meter,Products Show and the allowable deviation above m is no more than mm. The allowable deviation of horizontally installed pipes is mm per meter.

XcDuring the construction of building wall, cracks and hollows show that the construction materials are unqualified, the construction at the matrix junction is not in place, and the construction personnel are poor. The external wall plastering adopts electric welding steel wire mesh which can prevent cracking and strengthen the wall.

Galvanized pipe has excellent corrosion resistance

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.

gDifference and application description between H-beam and I-beam

BGalvanized pipe is a name for square pipe that is, steel pipe with equal side length. It is made of rolled strip steel after process treatment. Steel pipe has been an essential material in building decoration. Galvanized pipe is also used more in decoration,Products Show but hot-dip galvanized steel pipe manufacturers need to know about the size of galvanized pipe and several common sizes of galvanized pipe, which is helpful for your purchase!

pYIdentification method of galvanized pipe

Metric welded pipe: it is used as seamless pipe in standard. The welded steel pipe expressed by outer diameter * wall thickness mm is welded by hot and cold strip welding of general carbon steel, high-quality carbon steel or Puneng low alloy steel, or to transport fluid. The thin wall is used to produce furniture and lamps. It is necessary to ensure the strength and zigzag test of steel pipe.

The production methods of seamless pipe are roughly divided into cross rolling method and extrusion method. The cross rolling method is to drill the tube with a cross roll such as transmission shaft, and then extend it to the rolling mill. This method has fast production speed, but has high requirements for the workability of the blank. It is mainly suitable for the production of carbon steel and low alloy steel pipes. The extrusion law is to pierce the blank or ingot with a punch, and then squeeze it with a steel pipe with an extruder. The efficiency of this method is lower than that of cross rolling method. It is suitable for producing high-strength alloy steel pipe. The billet or ingot must be heated before cross rolling method and extrusion method. The produced steel pipe is called thermal correlation. Steel pipes produced by hot working can sometimes be cold worked as needed. There are two methods of cold working. One is cold drawing. In other words, pull the pipe to the pipe and tilt it to make the steel pipe gradually thinner and longer. Another method is cold rolling. The method of applying the hot smoke invented by brother to cold processing. The cold working of seamless pipe can improve the dimensional accuracy and finishing of steel pipe, and improve the mechanical properties of materials.

BWhat are the uses of I-beam?

Galvanized pipe features:

mU.S.AMetric welded pipe: it is used as seamless pipe in standard. The welded steel pipe expressed by outer diameter * wall thickness mm is welded by hot and cold strip welding of general carbon steel, high-quality carbon steel or Puneng low alloy steel,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd or it is made by cold drawing after hot strip welding. Metric welded pipe is generally used as structural parts, such as transmission shaft, or to transport fluid. The thin wall is used to produce furniture and lamps. It is necessary to ensure the strength and zigzag test of steel pipe.

pNSince the s, the welding quality has been continuously improved, the types, specifications and models of welded steel pipes are increasing, and seamless pipes have been replaced in more and more industries. Welded steel pipes are divided into straight seam welded pipes and spiral welded pipes according to the way of welding. Classified by production mode: classified by processing technology - electric arc welded pipe, resistor welded pipe, (high frequency, low frequency) gas welded pipe, furnace welded pipe.

Wire sleeve: it is also a general carbon steel welded steel pipe. It is used in concrete and various structural power distribution projects. The commonly used nominal diameter is from -mm. The wall of wire sleeve is thin, which is mostly used after coating or galvanizing, and cold bending test is required.
