Thread pitch is the distance between each thread on the screw's shaft
There are a variety of arc, non-divergence Angle and non-divergence height ladder types installed to provide ideal treatment plans. It can be used together with the appearance and the common design of the trackless active shift door, forming a harmonious and intact whole.
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.
With the development of mining industry, the classification of pig iron is already very broad in our country, which can satisfy the demand of mechanical industry. In general, the iron used to produce large rolls of galvanized wire can be divided into two classes. A metal exercised directly from the iron ore through the iron making stroke, the composition of the ore is iron oxide, silica and other miscellaneous stones. When this ore is specially refined into metal iron, carbon, silicon, manganese, and other elements are mixed into it. The material produced in this way is called ordinary pig iron, which is also the material for the first grade.
Post time: 08-07-22- The tensile resistance of welding net to 120N, otherwise for unqualified welding net. In this respect, there is no simple way to test the tensile resistance of the welding net, only through professional tools, expert testing to test, we will not introduce in detail. The outcrop on both sides of the welding net should not exceed 2MM. The welding net diameter wire and weft wire crossing place should be welded firmly, but the edge of the welding net to weld firmly weft wire must come out some, to weld firmly, but can not come out too much, generally not more than 2 mm is qualified welding net.
- For example, if the barbed rope is used for circling, the cost per meter is only a few yuan. If the other products are used for circling, it may be more than ten or even 20 yuan. This is undoubtedly to increase the cost of users again, so the barbed rope is the most economical and affordable product for breeding cattle and sheep.

Post time: 16-03-23- Hard black galvanized iron wire is made of low carbon steel wire directly drawn by drawing machine. The primary characteristics of hard black galvanized iron wire are high hardness and bright appearance. Primary use for welding hanger, umbrella, metal mesh, basket, basket and other metal products. Soft black galvanized iron wire is made of low carbon steel wire after annealing and softening, and then cold drawn. The primary feature of soft black galvanized iron wire is good flexibility, slightly higher hardness, bright appearance. Mainly used for metal mesh weaving process, electric welding mesh, welding process products.
- 5, after the light plating should be carried out light treatment.
- The characteristics of galvanized hexagonal net: easy to use; Save transportation costs. It can be shrunk into small rolls and involved in moisture-proof paper packaging, taking up little space. Coating thickness uniformity, stronger corrosion resistance; The construction is simple and does not require special technology; Strong resistance to natural damage and corrosion resistance and adverse weather effects; Can withstand a large range of deformation, and still not collapse. It has the function of fixed heat preservation and insulation.
Post time: 31-10-22- Hot-dip galvanized hexagonal net is another way of twisting hexagonal net corresponding to galvanizing.
- Steel mesh benefits: Compared with traditional handmade steel mesh, steel mesh has better elasticity and even spacing. When pouring concrete, the steel mesh is not easy to bend, and the thickness of concrete protective layer is easy to control and even. In bridge deck surfacing, measure the protective layer of steel mesh. The pass rate is 95 percent.

Post time: 18-08-22- Because the bundled galvanized wire is endowed with pre-tension, so it has the excellent characteristics of low relaxation value, small stress loss, good stability after loading, not easy to deformation, no fracture, strong elasticity, ordinary steel lines and rebar is difficult to match. The use of advanced galvanized finishing process, therefore, the use of hot-dip galvanized steel wire construction, not only good anti-corrosion performance, and beautiful generous. The product has the characteristics of smooth surface, high dimensional precision, good uniformity of zinc layer and firm adhesion.
Raw material of wire mesh sheet cold drawn low carbon steel wire base material can choose low carbon steel hot rolled disk bar or hot rolled smooth steel bar. The base material number and diameter of cold-drawn low carbon steel wire can be confirmed according to the rules in the table below. During the cold drawing process, the surface shrinkage rate of each drawing should not be greater than the wire mesh before cold drawing. Annealing shall not be carried out during wire drawing. If butt welding is required, the same production unit and base material of the same number should be selected. The appearance quality of wire mesh should not affect wire drawing. When the welding function is poor or brittle fracture occurs, special inspection should be carried out according to relevant standards.
- Wire mesh even in the mining industry also has a higher reflection, because the selection of low-carbon materials to do the material so that it has a general iron net class does not have flexibility, concluded that its plasticity in use, and then can be used in hardware crafts deep processing production, as the wall plastering, leak prevention crack and so on. Its light net body, lower cost, more can let customers experience its economic benefits.
Post time: 22-07-22The error of construction welding net diameter should be controlled at 0.02 mm. For example, we buy wire diameter of 89 wire welding net, with a micrometer to measure the diameter, the diameter of the allowable range is 87 -91 wire. In this range is qualified welding net. Because the accuracy has been compared, but no one can control it so well in the production process. The welding net can be accurate to 0.01 mm, so the error is allowed.
Post time: 07-02-23- So, do you know how to choose the right dog cage? Choose a dog cage to focus on quality and practicality! Let’s take a look:
- Since nose touching is an important part of a dog’s social behavior, humans can use this to train them. Experts say that if owners touch their dogs’ noses regularly when they are young, they will have softer personalities and be less likely to hurt.
- 1. Put the cat carefully in the special basin for washing the cat. Keep your cat as calm as possible.
Post time: 19-12-22- 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: 24-05-23- 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.
Post time: 08-09-225, 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.
Black iron wire application in the process, the main is through the hot metal billet rolling into six point five mm wire rod, and then put it in the drawing into a line of different diameter, the plant and then gradually narrow drawing plate aperture, cooling and annealing, plating process, such as making a variety of different specifications of the wire, the wire compared with ordinary black iron wire, will be more softer, Softness is also very uniform, color is also consistent, widely used in the construction industry, mining, chemical industry, welding mesh, welding coat hanger, reprocessing industry and so on.
