- 5, the guardrail cavity is equipped with galvanized steel lining or aluminum alloy to strengthen, with enough strength and impact resistance, so that the guardrail has the strength and beauty of steel. Stainless steel welding mesh can be used in the construction industry, highway, bridge for reinforcement. Used for mechanical protection, industry, agriculture, construction and so on.
- The wire mesh is finished by fine welding of active welding equipment. The material can be divided into cold drawing wire, hot dip galvanized, cold galvanized, dip plastic and so on. To be used for bridge reinforcement, deck paving, building reinforcement, etc.
The main difference between the two is the carbon content. The carbon content of iron is 2.11 percent or greater, while the carbon content of steel is 2.11 percent or less. The iron carbon alloy with carbon content above 2.11% is cast iron (pig iron), which is basically not malleable and cannot be drawn into wire. Secondly, the content of impurities is different. The content of harmful impurities such as sulfur and phosphorus in steel is smaller. Steel wire general color focus, iron wire color light point, white point.
- 5, after the light plating should be carried out light treatment.
The main customers of the barbed rope factory are still targeted at the farm and plantation customers for sales, because the demand for barbed rope is often very large.
Operating procedures: When using cold galvanized wire, all tools and stacked objects obstructing activities should be removed from the work site and equipment. When pickling, put the wire into the cylinder slowly to prevent acid splashing on the body. When adding acid, it is necessary to pour the acid into the water slowly. It is forbidden to pour the water into the acid to prevent the acid from splashing out. Wear protective glasses when working. Do not push or beat cold galvanized wire and other articles when handling them.
Advantages: The cost of hot dip galvanized rust prevention is lower than that of other paint coating. In suburban environment, the standard hot-dip galvanized rust prevention thickness can adhere to more than 50 years without repair. In urban or offshore areas, the standard hot-dip galvanized rust protection layer can last 20 years without repair. Galvanized layer and steel is a metallurgical connection, into a part of the steel surface, so the durability of the coating is more reliable.
- Thorn rope used to circle cattle and sheep and other livestock also has one of the biggest features is the price is relatively cheap, for users engaged in the breeding industry, the investment is not small, the use of thorn rope to fence on the one hand is to reduce the cost, on the other hand is the protection effect is better.
- A. When the thickness of the plating is 3-4 mm, the zinc adhesion should be less than 460g/m, that is, the average thickness of the zinc layer is not less than 65 microns.
The weight calculation method of hexagonal net is: the weight calculation method of hexagonal net: silk meridian.× silk meridian.× base x length x width ÷2=kg base: 1/2′=2.151′=1.273/4′=1.65/8′=1.875/4′=1.091′x1/2′ : 3′=0.4 silk warp. x silk warp. X 2x length x width ÷8×3=kg
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.
The wire mesh is composed of low carbon steel wire or medium carbon steel wire, high carbon steel wire or stainless steel wire. There are two kinds of manufacturing technology of steel wire mesh, one is the weaving method, the other is the welding connection, the formation of grid.
Post time: 05-01-233. Zinc layer structure: The structure of zinc layer includes grain size, grain shape and the combination of zinc layer and substrate, etc., which has a certain impact on corrosion resistance. In general, the finer the grain size, the denser the structure, and the better the corrosion resistance.
Post time: 18-07-22- Because the barbed rope is a strong use of regeneration value. Generally, the use of discarded guardrail networks for exercise, or steel production of new structural raw materials, do a good job of daily cleaning up and recovery can promote the value of the whole guardrail network faster. Again is to recover the use, the use of it in the appearance of the use of places that are not high, such as as other days purse Seine; Taking apart or discarding the raw materials that do not need to rust can carry out the whole regeneration.
- Galvanized hexagonal net is a kind of galvanized metal wire mesh, mesh shape is hexagonal.
The prepared black wire welding net is placed in environmental protection galvanized equipment for galvanized treatment. The surface of galvanized welding net is evenly covered with a layer of metal zinc. The corrosion resistance of zinc is very good and it is not easy to be oxidized. The wire diameter error of galvanized welding mesh is very strict, and the gap should be controlled at about 0.02 mm. But whether the tension of an electric welding mesh is qualified, can only be tested by professional tools.
- Zinc dipping time should be adjusted according to the thickness of wire diameter. The method of adjustment is to use the lead screw above the zinc pot, the length of the distance to the ceramic sinking roller. Thick wire diameter zinc dipping time should be long, fine wire diameter zinc dipping time should be short, zinc dipping length is in the range of 2~3.5m, which is also to reduce the zinc consumption of steel wire, is an aspect of maintaining the uniformity of zinc layer.

Post time: 28-12-22In order to orchard special electric galvanized shaft wire in alluvial surface to partially remove the surface film layer, surface impurity and other shortcomings can be found and solved according to the basic technology; Excessive foam is caused by soap and soapable surface active substances such as human fat into the tank. A moderate rate of foam production would be fine. The large amount of fine homogeneous particles in the tank can stabilize the foam layer, but the accumulation of too much solid particles will cause explosion.
- When pickling, the galvanized wire needs to be slowly put into the cylinder to avoid liquid splashing on the body. Protective glasses should be worn in the pickling process to prevent acid splash out and hurt people. Pay attention to safety when receiving the line operation, the line tray needs to be lightly placed, stacked neatly, not more than 5 disks. No matter what kind of auxiliary materials are used, galvanized wire drawing must comply with national regulations, otherwise it is not allowed to be used.
- 1. The content of alloying elements.
- The common barbed rope produced by the manufacturer is the 14*14 type of barbed rope product. Since the warp wire used is the same as the wire diameter of the barbed rope, it is easier to calculate the length and weight. Usually each kilogram of barbed rope can reach about 10 meters of service length. The length of each kilogram of raw material is about 35 meters. Since 35 meters of raw material wire diameter can produce 10 lengths of barbed rope cost.
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 belongs to a hook mesh, it is the selection of galvanized wire, hot-dip galvanized wire as raw materials, woven through the hook mesh truncated.
