In order to improve the corrosion resistance of steel pipe, the general steel pipe is galvanized. 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 characteristics of these cages are small, light, easy to carry and easy to clean. For small animal cage, the wire diameter of the general iron wire is not very large, the thickness of the plastic is relatively thin, so the use of the time can not be “violence”, otherwise the cage in the “destruction” will occur under the welding or plastic crack.

Many customers often ask: a kilogram of barbed rope to less than meters? How much does a barbed rope weigh in a meter? And so on the common problems, today Haorong screen manufacturers for everyone to answer.
3, a wide variety of specifications, a variety of shapes you choose, both European and American style and today’s popular fashion, full noble and modern beauty.
In summary, as a commonly used anticorrosive material, electrogalvanized wire has good corrosion resistance. Its corrosion resistance mainly depends on the thickness, uniformity and structure of zinc layer, substrate material and environmental conditions and other factors. Through reasonable electroplating process and material selection, the corrosion resistance of electrogalvanized wire can be improved and its service life can be extended.
Bridge protection system generally do not need to be specially installed special drainage system, the use of hexagonal mesh made of gabion mesh box, the inside of the filler are selected stones, these stones are not easy to wear, and between the stones and stones will retain some gaps, so it is very good to meet the drainage requirements.
Cold galvanizing (galvanizing) is in the plating tank after the current unidirectional, so that the zinc gradually plated on the metal surface, slow production speed, uniform coating, thin thickness, usually as long as 3-15g, bright appearance, poor corrosion resistance, usually a few months will rust. Compared with hot dip galvanizing, the production cost of electric galvanizing is lower.
With a large pickpocket used for steel wire, into the zinc liquid before the surface of the zinc ash stirring; Use a small outlet for galvanized steel wire; Zinc pot steel wire outlet in 30 minutes, with pickpockets back and forth, until the large, floating zinc residue into brown, real zinc ash, zinc ash surface. The extracted zinc ash should be brown yellow real zinc ash, zinc surface, effectively reduce zinc consumption. This is one of the biggest steps to bring zinc consumption down, and it’s a real problem, one that hasn’t been solved for years.
Relatively speaking, the wire is relatively soft, suitable for binding. Disadvantages are low hardness, low tension, easy to stretch, not suitable for building materials. In different applicable environment, we should make a reasonable choice. So in the usual use of cold drawing wire and wire, according to their own needs to choose, although the length of the same, but the performance is not the same.
Galvanized wire can be used zincate galvanized or chloride galvanized and other processes, appropriate additives should be used to obtain the coating required by the standards of low carbon steel wire. When the galvanized wire out of light plating should be carried out light treatment, the galvanized wire bath to control the temperature. Now the quality level of galvanized wire on the market is not equal, galvanized wire is also called hot dip zinc and hot dip galvanized, is an effective way of metal corrosion prevention, mainly used in various industries of metal structure facilities.
For key and important parts with tensile strength greater than 1034Mpa, the stress should be removed at 200±10℃ for more than 1 hour before plating, and for carburized or surface hardened parts, the stress should be removed at 140±10℃ for more than 5 hours. The cleaning agent used for cleaning shall have no effect on the binding force of the coating and no corrosion on the substrate. Acid activation Acid activation solution should be able to remove corrosion products and oxide film (skin) on the surface of parts without excessive corrosion on the matrix.
The tensile strength of cold drawn spring steel wire is slightly higher than that of oil tempered steel wire. The large specification of cold drawn steel wire elastic force is too large, winding the spring is very difficult, so the cold drawn spring steel wire application specification is generally less than 8.0mm, oil quenching tempered steel wire application specification is generally less than 13.0mm. In fact, the diameter of 13.0mm spring is used to light tension spring steel wire, cold drawing wound made into shape and then quenched and tempered. Steel wire with diameter above 15.0mm is mostly made by heating winding process.
3. Acid activation acid activation solution should be able to remove corrosion products and oxide film (skin) on the surface of parts, without excessive corrosion on the matrix.
The service condition and service life of electro galvanized iron wire or component are closely related to the thickness of electroplated coating. The more strict the conditions of use and the longer the service life, the thicker the layer of galvanized iron wire required. Different products, according to the specific environment (temperature, humidity, rainfall, atmospheric composition, etc.) to determine the expected service life of the coating thickness, blind thickening will cause all kinds of waste. But if the thickness is insufficient, it will not reach the expected service life requirements. Different manufacturers, according to their own equipment conditions, in the case of determining the plating, the first preparation of a more complete and reasonable process flow, clear plating parameters, control plating solution concentration, standard operation.

With the improvement of people’s living standards, now many families are raising some small pets, these small pets also need a safe nest, pet cage has become an important choice of people, each pet’s habits and living habits will choose to adapt to the cage.
Take the blade cord for example, the quality of the cord and the shape and direction of the surface barbs are what consumers need to consider. Professional materials in use can meet the needs of most consumers for materials, and the quality of these products is certainly to withstand the test, so if you really can not make up your mind, choose what kind of barbed rope, it is recommended to choose the best blade barbed rope.
Decorative hook mesh also has flexible characteristics can be used in different fields according to the needs of designers. When using hook mesh in corrosive environment, we must attach great importance to the selection of hook mesh parts materials. Now the hook mesh is often used in breeding fences, captive animals, protective gardens, etc., the wind and sun surrounding environment is difficult to ensure its life, some hook mesh in use for a period of time, due to exposure to the sun and humidity, will appear welding phenomenon, easy to shorten the service life.

We must have a certain understanding of the hexagonal net, we are swayed by the beautiful shape of the hexagonal net, not only the shape of the hexagonal net is very beautiful, in fact, the practical value of survival is very high. Hexagonal mesh of all kinds of guardrail, the value of the highway is more prominent, it is not only used in a variety of roads, in a variety of sports ball venues and landslides try to take care of, but also to reach a very close utility.
Unless the stainless steel blade barbed rope is specially customized, it is usually produced by the mould with the knife length of 22mm, which is the BTO-22 type we usually call. This is not necessarily the specification from 11mm to 65mm are specifications. Unless the customer insists on customized length requirements, the barbed rope manufacturer will produce BTO-22 stainless steel blade barbed rope.
