- No less than 5 disks should be extracted from each inspection lot for diameter error inspection. 1 point of steel wire should be extracted from each disk to measure steel wire diameter, and the actual diameter of steel wire at this point should be taken as the average value of the two vertical directions. The diameter error of cold-drawn low carbon steel wire should conform to the rules in the table below. The unqualified inspection batches shall be checked one by one, and the qualified batches can be used for engineering.
Galvanized hexagonal mesh features: easy to use; Save transportation costs. It can be reduced into small rolls, and involved in moisture-proof paper packaging, occupying little space. Coating thickness uniformity, corrosion resistance is stronger; Simple construction, no special technology; Strong resistance to natural damage and corrosion resistance and the ability to resist adverse climate impact; Can withstand a wide range of deformation and still not collapse. Play the role of fixed heat preservation and insulation.
- 6. The barbed rope protective net should be laid according to the terrain of the road boundary. The flat section should be set horizontally, and the slope section should be set along the slope or by the step form.
- In addition to these reasons, we should also pay attention to the tooling and process must be stable, and regular testing should be done to ensure the uniformity of galvanized layer.
Post time: 11-01-23After annealing, the extension rate of galvanized wire is increased, making the product more soft and increasing the scope of application of galvanized wire. After electric galvanized hot galvanized, electroplated copper and other widely used screen production. Building reinforcement binding with galvanized wire mesh braided with the first after plating, plating and other methods, after treatment of galvanized wire mesh or steel wire mesh, has good corrosion resistance, oxidation resistance characteristics, can be used in construction, petroleum, chemical, aquaculture, garden protection, food processing and other industries reinforcement, protection and heat preservation.
- (2) Spray large number hook mesh guardrail should be used electric spray paint or electrostatic spray paint.
Wire-wall welding net is widely used in industrial production, agriculture, engineering construction, transportation, mining and other processing and manufacturing industries. Such as machinery and equipment protective cover, animal guardrail, pot flower guardrail, window fence, safety exit guardrail, poultry cage, egg basket and home office food industry basket, paper basket and design decoration. It is suitable for general engineering building wall, pouring concrete, multi-storey building, etc., which plays an important structural role in the thermal insulation system. In the construction of the building, the thermal insulation board of hot-dip galvanized electric welding grid is placed on the inside of the outer mold of the wall to be concreted. The external thermal insulation board and the wall are one kind of live, and the thermal insulation board and the wall are integrated into one body after the removal of the mold. The coating on the surface of the weld core is called the coating. The coating of electrode plays a very important role in the welding process. If the photoelectrode without drug skin is used for welding, in the welding process, oxygen and nitrogen in the air will invade a large number of molten metal, metal iron and beneficial elements such as carbon, silicon, manganese oxidation and nitriding to form various oxides and nitrides, and residual in the weld, resulting in slag inclusion or cracks in the weld. The gas in the weld pool may produce a large number of pores in the weld. These factors can greatly reduce the mechanical properties of the weld and make it brittle.
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.
- 1, barbed rope protection net center line along the road within the land boundary 20 to 50 cm set.
After annealing, iron wire will become softer and more flexible. Iron is a more active metal, and more active than hydrogen, so it is a good reducing agent. At room temperature, iron is not easy to react with oxygen, sulfur, chlorine and other non-metallic elements in dry air, its production cost is low, the use and scale is relatively wide, better protective function, so it is an important material for steel parts used in strict working environment.
Post time: 09-06-22The main reason for the high price of stainless steel barbed wire is that the raw material used in the barbed wire is more expensive, because the nickel in it makes it corrosion resistant and ductile. Stainless STEEL BARBED ROPE IS a new type of protective products, precisely because of its corrosion resistance in coastal or often acid rain landing site is widely used, the service life of up to 15 years.
Annealed wire is mainly made of soft iron wire through low carbon steel heating, hot drawing, constant temperature and other processes. Because of the differences in use, there are also different in the production process, and the specifications are varied. Annealed wire can be widely used, mainly because annealed wire and other kinds of wire, has many advantages.
Paint on the galvanized layer, the binding force between each other and the baking temperature of the paint has a great relationship, after galvanized coating alkyd paint, adhesion is no problem. Galvanized amino paint, paint adhesion is not good. Do two bottom two surface, adhesion is ok, if the two bottom two surface to two bottom three surface, that is, more paint, more baking once, again test adhesion is very poor, poor to the paint from the galvanized layer of pieces torn off.
Post time: 27-04-23There are many kinds of galvanized solution, which can be divided into cyanide plating solution and cyanide plating solution. Cyanide galvanizing solution has good dispersion and covering ability, coating crystallization is smooth and fine, simple operation, wide application range, has been used in production for a long time. However, because the plating solution contains highly toxic cyanide, the gas escaping in the plating process is harmful to the health of workers, and the waste water must be treated strictly before discharge.
- Tolerance range: radial mesh deviation range is not more than ± 4%, zonal mesh deviation range is not more than ± 3%; Solder joint tensile strength exceeds the national standard.
The characteristics of this kind of small animal cage, is small, light, easy to carry, but also easy to clean care. For small animal cages, 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 “violent”, or the cage under the “destruction” will occur welding or plastic crack off.
Enclosure to calculate the use of barbed rope, so as to reasonably plan to purchase the amount of barbed rope to facilitate construction
- Of course, these are limited to the maintenance of the indoor balcony, so outdoor, some of this is less than maintenance, some maintenance will waste resources, because of the expected life, in order to ensure the safety of the role, timely update is good.
- Scope of use: Because the obtained coating is thicker, hot-dip galvanizing has very good protective function than electric galvanizing, so it is an important maintenance coating for iron and steel parts in strict working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, electric power transportation, shipbuilding and other occupations. In agriculture, such as pesticide irrigation, greenhouse and construction industry, such as water and gas transportation, wire casing, scaffolding, Bridges, highway guardrail and other aspects, have been widely used in these years.
Then are there other barbed rope products with the same ability to prevent corrosion at a lower price? The answer is yes, the latest zinc-aluminum alloy barbed rope developed by our factory is a relatively new type of barbed rope products, which has anti-corrosion anti-aging ability can effectively prevent rust aging of barbed rope, at the same time the price is lower than stainless steel barbed rope, only half of it.
- Second, positive and negative twisting rope cost-effective
The type of barbed rope is mainly reflected in the specification of the wire diameter, the thicker the diameter of the barbed rope produced is shorter, at the same time, the price is cheaper, mainly because the production efficiency is relatively high, because the price of the barbed rope is calculated according to the weight when it is sold. On the contrary, the finer the diameter of the wire, the longer the price is higher.
- ⑵ Can realize the welding of large plate, steel frame, plate – tube, rod – rod, tube – tube and other profiles.
Plastic coated welding net: PVC plastic coated welding net is a kind of tall appearance of the welding net, plastic coated welding net picture upper protective barbed net, cable for galvanized steel wire, PVC coated plastic treatment, in the protection of beautiful at the same time, to ensure the strong and durable.

PVC coated plastic welding net uses: industrial, agricultural, municipal, transportation and other industries fence, decoration, protection and other facilities.
- Packing is also very important. The cut wire should be bundled and tightly packed with plastic film, and then placed in a regular box. The whole box should be filled and sealed. It is better not to have half a box.
- Annealed wire is a kind of soft iron wire made of low carbon steel by cold drawing, heating, constant temperature and heat preservation. The composition of the wire varies according to its use. It contains iron, cobalt, nickel, copper, carbon, zinc, and other elements. The hot metal billet is rolled into 6.5mm thick steel bar, that is, the wire rod, and then it is put into the wire drawing device to draw the wire of different diameter, and gradually reduce the aperture of the drawing disk, cooling, annealing, plating and other processing technology to make a variety of different specifications of the wire.
- Three is to do a good job in the production of galvanized wire products clean and tidy, in accordance with the scientific method of operation to operate the production, the operator should wear the required dress. If it is hot dip galvanized wire products, we must do a good job of passivation, will be able to effectively prevent discoloration, prolong the method of discoloration, can solve the problem of discoloration.
