  • Galvanized steel pipe is divided into hot dip galvanized and electric galvanized. The layer of hot dip galvanized is thick, the cost of electric galvanized is low, and the surface is not very smooth. Used for steel blowing oxygen pipe, generally with small diameter welded steel pipe, specifications from 3/8-2 inches of eight. Made of 08, 10, 15, 20 or 195-Q235 steel strip, in order to prevent corrosion, some should be aluminized.

  • The basic components of the bird cage are plate top, cage frame, cage bar, cage door, cage hook, dragon ring, bottom ring and cage bottom. The accessories are composed of dung board, sun rod, bird seed pot, water tank, jade finger, horsetail string, etc. These parts are usually made of wood or bamboo, and can be carved and hollowed out with a variety of laser machines.

  • Deoxygenation of boiling steel is incomplete, oxygen content is high, phosphorus and other impurities distribution is uneven, local overspending, aging sensitivity and cold brittle sensitivity are high, hot cracking tendency is added. If unqualified electrode is used, if the content of carbon and sulfur in the weld metal is too high, cracks will occur. For example, when factories use acidic electrodes to weld Q235-A steel, the high carbon fernoganese in the electrode coating will lead to thermal cracks in the weld.
  • Large aperture hexagonal mesh is also called large size hexagonal mesh, large wire hexagonal mesh, heavy hexagonal mesh, heavy stone cage mesh, gabion mesh, large wire mesh, is the use of 1.8mm-4.0mm metal wire diameter by mechanical woven into the twisted hexagonal wire mesh products.

  • 2, reduce the bivalent iron ion in the plating aid used for hot plating wire, reduce the formation of zinc slag

  • Customers in the order of wire mesh will often shop around, most customers are in comparison with manufacturers to give the product price, the company tells you, do not blindly compare the price. To standards, production technology, manufacturers and other factors lead to different prices.

  • Especially after passivation of galvanized layer, the surface of the oxide layer is thicker and compact, itself has high oxidation resistance. On the other hand, when the surface of the galvanized layer is damaged, exposing the inner iron matrix, because zinc is more active than iron, zinc will bear the role of sacrificing zinc anode, zinc will be oxidized before iron, so as to protect the iron layer will not be damaged.

  • Electric galvanized shaft wire direct selling is in the plating tank through the current unidirectional zinc gradually plated on the metal appearance, the production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust. Compared with hot dip galvanizing, the production cost of electric galvanizing is lower. The difference between cold galvanizing and hot galvanizing: the difference between cold galvanizing and hot galvanizing is that the amount of zinc is different. They can be identified from the color. The color of cold galvanizing is shiny silver white with yellow. Hot dip galvanizing shiny white.

  • Large roll galvanized wire can be divided into hot-dip galvanized wire and cold galvanized wire, the difference between the two lies in the way of zinc and the amount of zinc. Hot dip galvanizing is to soak steel wire in melted zinc liquid, hot dip galvanizing zinc fast, zinc layer thick rust prevention performance is very good, but the zinc is not uniform, and the surface is dark, the life of hot dip galvanizing can reach 20 years.

  • After proper heat treatment or cold drawing hardening, high carbon steel wire has high strength and hardness, high elastic limit and fatigue limit (especially notched fatigue limit), cutting function is acceptable, but welding function and cold plastic deformation ability is poor.

  • Because the anti-aging and anti-corrosion ability of zinc-aluminum alloy wire is much higher than galvanized barbed rope, it is widely used in all kinds of places where personnel are scarce and lack of maintenance ability, and is used for island protection in coastal areas
  • Now most people buy barbed rope choose blade barbed rope, why is this? The blade gill net is made of hot-dip galvanized steel plate or stainless steel sheet to punch out sharp knife sheets. The high tension galvanized steel wire or blade barbed wire is made of stainless steel wire as the core wire. Because the gill net shape is not easy to contact, so it can reach excellent protection barrier effect. The primary raw materials of the product are galvanized sheet and stainless steel plate.

  • 3, pasture installation of barbed rope column to choose strong impact resistance zinc column, and coupled with oblique column fixed. Due to the large size of livestock, although there is a barbed rope to deter but inevitable collision phenomenon, in order to the stability of the fence recommended to use zinc steel post.
