  • The height of the shield should not be less than two meters. The length of the shield should be the width of the journey and the extension 10 meters away. The vertical load of the handrail on the bridge is 1.2KM/m, and the horizontal external load is 2.5KM/m, both of which should be calculated separately. Galvanized hook mesh is attributed to a hook mesh, it is the selection of galvanized wire, hot dip galvanized wire as raw materials, woven through the hook mesh crimping truncated.

  • In white iron, its carbon and iron phase into iron carbide, crack white, extremely strong and brittle, for the malleable steel material. Alloy grades are made up of various alloying elements with different compositions and structures. Because the alloy element in the iron can make the copper material thick strengthening degree, hardness, impact force, strength resistance, collection rate, elongation rate, so the alloy iron in the exercise of high quality iron, is an additive element.

  • They are good at expressing unspoken feelings to people. Their owners feel respect, dependence, admiration and affection. The process of caring for pets inspires people’s sense of responsibility, brings more meaning to people’s life, and helps people establish the fulcrum of life and confidence in life. In fact, dogs are very malleable animals. Through scientific and rational training, you can become a popular family member.

  • Out-of-line annealing means that the recrystallization annealing of hot or cold rolled steel plate is carried out in the bottom type annealing furnace or cover type annealing furnace before entering the hot plating wire line, so that there is no annealing process in the galvanized line. The steel plate must maintain a clean active surface of pure iron, free of oxides and other dirt, before hot dip galvanizing. In this method, the annealed surface oxide sheet is first removed by pickling method, and then coated with a layer of zinc chloride or a mixture of ammonium chloride and zinc chloride solvent for protection, so as to prevent the plate from being oxidized again.

  • Combined restrictions of fence network and maintenance network: Plot fence network, garden villa, private swimming pool, courtyard on the lawn, city scene, municipal transportation, sports venues, airport port, office school, military equipment, prison farm, industrial park, tourist resort, distribution center, The specifications and parameters of the fence network are as follows: 800, 1000, 1200, 1400, 1600, 1800, 2000, 2200, 2400 (mm) : 2000, 2500, 3000 mesh spacing (mm).

  • Some customers are more concerned about quality problems, so for the service life is more important, barbed rope factory will generally recommend the use of high zinc barbed rope or stainless steel barbed rope.

  • The composition of hot dip galvanizing layer is composed of hot dip galvanizing layer, which is composed of iron zinc alloy between iron matrix and surface pure zinc layer. The shape of the workpiece is formed by the iron zinc alloy layer in hot dip, so that the iron and pure zinc layer touch outstanding. When the iron workpiece is immersed in a molten zinc solution, the initial zinc and iron (body) are formed at the interface. This is a crystal made up of zinc atoms in the solid metal iron. When two metal atoms are fused together, the gravitational force between the atoms is very small.

  • There are many kinds of specifications for crack resistant welding mesh used in the construction industry. The commonly used specifications are as follows:

  • The screen is made into a box-like container, with stone filled with cages, can be used to protect and support seawall, hillside, road and bridge, reservoir and other civil engineering, flood control and flood resistance is a good material.

  • No matter how big they are, dogs seem to love touching noses with people and other animals. In fact, nose touching is a form of social interaction for dogs, much like shaking hands and hugging humans. But dogs don’t rub their noses with every person or animal. They choose who to rub their noses with. If they don’t like you or don’t know you at all, they won’t touch your nose. However, adult dogs will touch the nose of almost every puppy. They will not only touch the puppy’s nose, but also smell the puppy.

  • There are two main points to choose the blade to stab the rope

  • Cold galvanizing, also called galvanizing, is the steel wire placed in the plating tank, through the one-way current to make the metal surface slow galvanized, zinc is slow, and the thickness is only one tenth of hot dip galvanizing, zinc layer is thin, so the rust resistance is not good, placed in the outdoor usually a few months will rust, applied in the outdoor generally in the plastic coating.
  • Steel mesh manual binding line of the joint simple sliding, steel and concrete strength is weak, simple crack. The welded joint can accept not only pressure but also shear force. Longitudinal and transverse steel bars form a network structure, which plays a bonding anchorage effect. The number of solder joints per unit area is added when the diameter of the wire mesh is small and closely spaced. More conducive to strengthening the crack resistance of concrete, can reduce more than 75 percent of the attack of steel mesh cracks is a new, energy-efficient steel mesh structure, used in beams and columns, floors, roofs, walls, concrete pavement, bridge deck paving and other industrial and civil buildings.

  • The large roll of galvanized wire is violently extinguished in oxygen and sparks radiate, while the sodium block and magnesium bar are extinguished in oxygen and no sparks radiate. This phenomenon is determined by the composition of large rolls of galvanized wire. The large rolls of galvanized wire used in the experiment are pig iron or steel wire, both of which are alloys of iron and carbon (complex substances containing the elements iron and carbon). When the carbon in galvanized wire is extinguished, carbon dioxide will be produced, and the solid will be changed into a gas, and the volume will shrink rapidly.

  • In addition, hot-dip galvanized wire also needs to pay attention to maintenance and maintenance during use. Although it has good corrosion resistance, the zinc-iron alloy protective layer of hot-dip galvanized wire will gradually wear out after a long time of use. Therefore, regular inspection and maintenance of the surface of hot-dip galvanized wire, such as recoating or anti-corrosion treatment, helps to extend its service life.
