Compared with manual binding， welded steel mesh can reduce the occurrence of cracks by more than %. The use of reinforcement mesh can make the project construction faster. As long as the reinforcement mesh is laid as required， the concrete can be poured， eliminating the links of reinforcement on-site cutting， placing one by one and binding. It can save % - % of working hours， greatly accelerate the construction progress and shorten the construction cycle.

From the point of view of the strong zinc corrosion resistance of the barrier layer， when the zinc sacrificial anode is at the forefront of protection， the scratches and scratches of some coatings and the insolubility of zinc oxide layer play a protective and blocking role.
fOakvilleStages needing attention in the production and manufacture of alloy tubes
The laying of reinforcement mesh can speed up the construction speed and shorten the construction period. In order to reduce the impact of construction on road traffic， the reinforcement and maintenance works of the two bridges are expected to be completed in the middle of next month.
SAzerbaijanThere are many processes in the process of welded pipe processing， and every detail needs our attention. Welded pipes need to be treated by various processes before application. Heat treatment of welded steel pipe is an important link in the process of welding steel pipe. Hot working is a metal hot working process in which metal materials are heated， insulated and cooled in a certain medium， and the metal properties are controlled by changing the metallographic structure on the surface or inside of the material.
FoWhen the beam width is small， the reinforcement shall be bent.

In view of the current market environment， especially in terms of construction or equipment manufacturing technology， the position of galvanized pipe is still relatively large. It is precisely because of this strong position that we can see this kind of building material in all walks of life， even in a field that seems to have little contact. It will be applied in many construction projects. At the same time even in the depressed environment of the steel industry， the application situation and utilization rate of this kind of pipe are very high.
eI-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 -， that is， the corresponding height is -. At the same height，Products Show the light I-beam has narrow flange， thin web and light weight. Wide flange I-beam，Londres45 tubes en acier sans soudure de grand diamètrePiloter le développement de l'industrie 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.
YGalvanized 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， weldability， cold and hot workability and corrosion resistance，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd and good low temperature toughness.
CWelcome calls Seamless pipe
uYGalvanized steel pipe: in order to improve the corrosion resistance of steel pipe， general steel pipe (black pipe) shall be galvanized. Galvanized steel pipes are divided into hot-dip galvanizing and electro galvanizing. The hot-dip galvanizing layer is thick and the cost of electro galvanizing is low.
Galvanized pipe is often seen in our daily life， especially in some construction sites. This product has the advantage of durability when used. It also has the characteristics of surface gloss uniform zinc layer and no missing plating. Moreover， the cost of hot-dip galvanizing for rust prevention is lower than that of other paint coatings. In addition this product also has the characteristics of no dripping， strong adhesion， breaking the clean Legion and strong corrosion resistance. Even if it is used in some places where the environment is not good， its service life is also very long， and it also has the characteristics of corrosion resistance. The standard anti rust thickness of hot-dip galvanizing can be maintained for more than years without repair. This is used in some suburban environments. However， in urban or offshore areas， standard urban or offshore areas can be maintained for years without repair. The products produced by our company must meet these requirements. Friends who need to order can call us directly.
Manganese: it can improve the strength of steel， weaken and eliminate the adverse effects of sulfur， and improve the hardenability of steel. High alloy steel (high manganese steel) with high manganese content has good wear resistance and other physical properties
wholesaleruWelded pipes with large or thick diameter are usually made of steel blank immediately， while small welded pipes and thick wall welded pipes must only be welded immediately according to nylon tape. After simple grinding and polishing， metal wire drawing is OK.
DThe specification of pass design I-beam is expressed in cm of waist width. For example， the waist width of No. I-beam is. The types of I-beam include hot-rolled ordinary I-beam， expressed as No. ~ No.， I-beam can also adopt special rolling method.
The whole structure is composed of zinc and quaternary crystals cross pass system and mixed pass system. In addition， forming dense crystals and barrier layer on the plate， which effectively prevents the penetration of corrosion factors. From the point of view of the strong zinc corrosion resistance of the barrier layer， when the zinc sacrificial anode is at the forefront of protection， the scratches and scratches of some coatings and the insolubility of zinc oxide layer play a protective and blocking role.
vOakvilleLongitudinal welded pipe has the advantages of simple production process， high production efficiency， low cost and rapid development. The strength of spiral welded pipe is generally higher than that of straight welded pipe. It can produce welded pipe with larger pipe diameter with narrow blank， and welded pipe with different pipe diameter with blank of the same width. However， compared with the straight seam pipe with the same length， the weld length increases by ~ ， and the production speed is low. Welded pipes with large or thick diameter are generally made of steel blank directly， while small welded pipes and thin-walled welded pipes only need to be welded directly through steel strip. Then after simple polishing， wire drawing is OK. Welded pipe is welded with strip steel， so it is not as high as seamless pipe in its original position. Welded pipe process: uncoiling of raw materials - leveling - end shearing and welding - looper - forming - Welding - removal of internal and external weld beads - pre correction - induction heat treatment - sizing and straightening - eddy current testing - cutting - hydraulic inspection - Pickling - Inspection (strict control) - Packaging - delivery.
fMMetric 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 it is made by cold drawing after hot strip welding. Metric welded pipe is generally used as structural parts， 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.
