3mm perforated steel sheet

Hot dip galvanizing is the plating of zinc layer on the surface of Angle steel, channel steel and other metals to achieve the appearance of convenience and rust prevention of metal. Hot-dip zinc processing plants use zinc tin solution to prevent corrosion on the workpiece. This new technology can extend the corrosion time by up to five times, which is usually used in outdoor construction. Because the principle of action is not the same, so the role of the workpiece is not the same. The appearance of hot dip zinc plant is only to expand the scope of action.

Arrived in other ways can’t end effect of the inclination of hook flower network structure in essence is void, water permeability, the natural effect of groundwater and filtering effect has a strong inclusive, suspended in the water content and silt accumulation in fill in crevices, applied to mountain protection, is conducive to the growth of natural plant, beautify the grass spraying to arrive late his curing effect, Gradually restoring the original ecological environment is a perfect connection between beautification and protection.

Hexagonal cage has a wide range of applications, with the progress of science and technology, has been extended to the major hydraulic engineering, civil engineering. Geotechnical engineering and other projects. In the hydraulic hexagonal cage in the river construction to reach the utility, that is appropriate and the use of hexagonal cage used to fill stone, fixed river, can avoid river erosion bring water and soil loss. In the civil engineering project, the hexagonal cage is considered appropriate and the use of similar particle size volume particle filling, cage between the formation of a mesh wall, which is the stone cage mesh retaining wall.taining wall.

Spray powder mainly acrylic powder, polyester powder and so on. Dipping is a kind of plastic coating process, that is, the plastic coating on the matrix, generally metal, such as: daily use of clothes hangers, pliers handles, scissors on the rubber sleeve, various handrails, etc. Plastic immersion is to heat the metal to spray plastic powder evenly on the metal to form a plastic film, or heat immersion liquid into the metal to cool it and then plastic coating on the metal surface.

The application of electric welding net is more widely, at present it has replaced the use of other parts of the wire mesh, the cost of electric welding net is lower, the production speed is very fast, so it is very popular. Welding net galvanized before the need for processing is recrystallization annealing, because the welding net must maintain a no oxide and no other impurities of pure iron active surface, if you can not keep its surface clean will lead to a bad galvanizing effect, galvanized layer and iron material is not closely combined, so this step is necessary.

If the zinc coating is good, but in 3% nitric acid when the light, the coating has dark shadow, passivation occurs when the film is brown, may be caused by foreign metal impurities such as copper or lead in the galvanizing liquid. When problems occur in the process of galvanizing large coil galvanized wire, the temperature and current density are checked first, and then the content of zinc and sodium hydroxide in the plating solution is measured and adjusted through the analysis of the plating solution. Whether DPE content is low can be determined by hull cell test.

Nestor rolling cage, high-speed railway Nestor rolling cage and railway Nestor rolling cage are all produced, sold and installed in accordance with the technical requirements of the reference drawing of railway line 2012-8001. Nestor rolling cage is a kind of protective equipment emerging in railway in recent years. Nestor rolling cage is connected by Nestor connecting clip on the longitudinal tensile rib fixed on the bracket. The longitudinal tension and the support are connected with the Φ2.5mm cold-drawn galvanized steel wire around 2 laps and then tightened. The support is set in the column and the middle of the span of the protective fence of 3m. The other spans are only set with the upper column, and the support and the protective fence are connected with the bracket hoop. For the protective fence that has been installed with metal mesh, the Nestor roller cage is directly fixed on the transverse sheet and wire of the metal mesh with the cold-drawn galvanized steel wire of 2.5mm or the Nestor connection fastener.

We must have a certain understanding of the hexagonal net, we are swayed by the beautiful shape of the hexagonal net, not only the shape of the hexagonal net is very beautiful, in fact, the practical value of survival is very high. The introduction of the relevant information should be very clear to know the high-speed road guardrail network, hexagonal mesh of all kinds of guardrail network, the value of the high-speed road is more prominent, it is not only used in a variety of roads, in a variety of sports ball venues and landslides to take care of, but also to reach a very close utility.

Defects such as surface film and surface inclusions can be found and treated by conventional techniques in order to remove them locally from the surface of the deposition layer. Excess foam is formed when soap and surfactants such as saponified fats are brought into the tank.

Galvanized hook mesh standard is thorough, mesh planning: 3cm-20cm, silk planning: 1.2mm-4.5mm, galvanized hook mesh 6000 square meters, some standards are available. Benefits: The selection of low carbon steel wire, surface for cold galvanized (electric galvanized) hot dip galvanized anticorrosion treatment, mesh wire strong, strong protection, long anticorrosion time.

Heavy hexagonal net, also known as large size hexagonal net, or gabion mesh, made of steel wire by twisting mesh machine. This product is very versatile. Can be used for slope support, foundation pit support, mountain rock surface hanging net shotcrete, slope planting (greening), railway highway isolation barrier, it can also be made of stone cage, stone pad, for rivers, DAMS and seawall anti-erosion protection and reservoirs, river interception with stone cage.

Because the coastline is generally erected for protection, but often because of environmental factors lead to serious corrosion of the barbed rope lost its function. Stainless steel barbed rope is specially set up to prevent corrosion. Stainless steel barbed rope because the environmental requirements are not very high can be very good protection itself will not have a problem to extend the use of life, so that you can ensure safety.
