different types of construction nailsLarge volume galvanized wire is made of high quality low carbon steel wire rod processing, is made of high quality low carbon steel, after drawing molding, pickling rust removal, high temperature annealing, cooling and other processes. Galvanized wire has good toughness and elasticity, the amount of zinc can reach 300 grams/square meter, with thick galvanized layer, strong corrosion resistance and other characteristics. Widely used in construction, handicrafts, silk screen preparation, highway guardrail, product packaging and daily civil and other fields. Galvanized wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire).

different types of construction nailsSelect cut wire first of all to ensure that the raw material of the silk is exactly the raw material you need, the raw material to ensure that it will be used well. Choose the straightness is relatively high, so that the length of the truncation will be the same, there will not be a lot of length difference, the length of the truncated wire is a very important element to select the truncated wire.

different types of construction nailsIf the zinc coating is good, but when the light comes out in 3% nitric acid, there is a dark shadow on the coating, and the film is brown when passivation occurs, which may be caused by foreign metal impurities such as copper or lead in the galvanized liquid. When there is a problem in the process of galvanizing, check the temperature and current density first, and then measure and adjust the content of zinc and sodium hydroxide in the bath through the analysis of the bath. Whether DPE levels are low can be determined by Hull cell test.

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.

Post time: 28-02-23After proper heat treatment or cold drawing hardening, high carbon steel wire has high strength and hardness, high elastic limit and fatigue limit (especially notched fatigue limit), cutting function is acceptable, but welding function and cold plastic deformation ability is poor.
Some large roll galvanized wire products in order to meet different industrial needs, will be further processed on the surface, such as the anti-corrosion layer, galvanized, iron plating, aluminum alloy plating, or in the galvanized wire appearance above the copper plating, brass plating, etc., to strengthen the steel wire and colloidal years and capabilities. Generally, galvanized wire products should be well plated and drawn when they are produced, and the sequence of the two processes should be decided according to the production or industrial needs.

Hot-dip galvanized wire is widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, electric power transmission, shipbuilding and other industries. It has been widely used in recent years in agricultural fields such as agricultural medicine sprinkler irrigation, greenhouse and construction industry such as water and gas transmission, wire casing, scaffolding, Bridges, highway guardrail and so on.

1, first of all, the net surface is smooth, mesh are four lines, pitch is the same, whether the weft wire bending (note: the net width is the length of the weft wire), normal weft wire passes through the straight wire of welded wire mesh, with accurate time and the silk repeated welding, make the pitch of welded wire mesh is consistent, with smooth surface, into a square hole, when the net vertical position from the top downwards see, weft wire is straight.
