Greenhouse steel pipe is mainly made of greenhouse composite materials made of pull rod, pressure rod, column, and arch rod to cover the plastic film in a greenhouse. Wire factory introduces its this shape is circular plastic greenhouse, this greenhouse covers a large area, the effect of heat absorption is also very good, convenient to build, the cost of building a is also very low. The raw material source of greenhouse steel pipe is very rich and extensive, and the application effect is good.

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.

We must have a certain understanding of the hexagonal network, we are the beautiful appearance of the hexagonal network, hexagonal network is not only very beautiful appearance, in fact, the practical value of survival is very high. To introduce the relevant information should be very clearly know the highway guardrail net, hexagonal wire netting in all kinds of fence netting, in the value of the high-speed on the road more MaoJian, it not only be used in all kinds of road, in a sports ball games venue and try our best to take care of landslides, also has reached very matter effectiveness.

Stainless steel is short for rust acid steel, air, steam, water and other weak corrosion medium or stainless steel is called stainless steel; And the chemical corrosion resistance medium (acid, alkali, salt and other chemical etching) corrosion of steel called acid steel.

3, reduce the bivalent iron ion in the plating aid used for hot plating wire, reduce the formation of zinc slag

If 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.
