Hexagonal mesh is a metal wire woven Angle mesh (hexagonal) made of wire mesh, the use of metal wire diameter is based on the size of the hexagonal and different. Also known as: twist flower net, stone cage net, gabion net, flood control network.

Its specific design layout principle is:

Cold wire drawing is mainly used in the production of hardened low carbon steel wire, with a diameter of 8 mm steel bar to play a fixed role in the development of the construction industry has played a role in promoting the development of the construction industry, widely used. The bonding and anchorage performance between cold wire drawing and concrete is good. When used in components, the phenomenon of cracking in the anchorage area of components and damage caused by steel wire slip is fundamentally eliminated, and the bearing capacity and anti-cracking capacity of the end of components are improved.

Immersed six edge barbed wire corrosion lost the original characteristics, in the shape, color and mechanical properties and other aspects will change, resulting in equipment damage, pipeline leakage, specifically, is prone to fracture, lose the original protection function. Corrosion usually metal corrosion has three types: physical, chemical corrosion and electrochemical corrosion, and corrosion depends on the chemistry of the metal itself and the organizational structure, still have relationship with the surrounding medium, such as wet environment than dry environment is easy to rust, more less than the impurities of impurities is easy corrosion, high temperature conditions than under the condition of low temperature corrosion, etc. After understanding these, we can effectively prevent the corrosion of the six sides of the wire, prolong the service life of the product.

The main difference is carbon content. Iron has a carbon content of 2.11 percent or more, while steel has a carbon content of 2.11 percent or less. Iron-carbon alloys with carbon content of more than 2.11% are cast iron (pig iron), which are basically not malleable and cannot be drawn into wire. Secondly, the content of impurities is different, and the content of harmful impurities such as sulfur and phosphorus in steel is smaller. Wire general color key, wire color light point, white point.

Specific requirements for the safety of galvanized wire production: clean up all tools and other objects that hinder production in the galvanized wire production environment. Operators in the pickling process, pay attention to the action should be careful, not careless, into the pickling tank must be handled lightly, to prevent splashing on the body. When adding acid, the acid must be slowly poured into the water. It is forbidden to pour the water into the acid, so as to prevent the acid from splashing out and hurting people. Do not hurt yourself or others.

The shape of the cage has round, square, octagonal, hexagonal and other shapes. Because the circular space uses a large area, it is more suitable for the activities of birds, and it is not easy to get hurt, so it is popular with everyone. A cage is dear to a man who loves birds, for it is inhabited by his master’s birds. If well maintained, it can be maintained for many years. Let’s look at how to maintain the cage.

With the technique of preventing the coating from peeling off the hook mesh, hook tennis court chain link fence systems have long tended to define lines that economically attach amenities and add value to the property. The interlocking system also allows deductions for easy attachment control.

Hot dip galvanizing is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot dip galvanizing is to first pickling the iron and steel parts. In order to remove the iron oxide on the surface of the iron and steel parts, after pickling, it is cleaned in the tank of ammonium chloride or zinc chloride aqueous solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent into the hot dip plating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.
