Such as machine shields， animal fences， flower and tree fences， window fences， aisle fences， poultry cages， baskets and decorations.
8Galvanized pipe is a layer of galvanized ordinary steel. This is a layer and is a great anti-corrosion protection.

The monthly summary of the real estate industry shows that there is a significant positive correlation between the market sales and the long-term trend of the apparent consumption of galvanized pipe， but there will also be a backwardness of the market in a special stage， and after the backwardness of the market in stages，Products Show there will be a rapid decline in the moving average of the apparent consumption of galvanized pipe， square steel pipe， oval steel pipe， triangular steel pipe， hexagonal steel pipe， rhombic steel pipe octagonal steel pipe， semi-circular steel pipe， others.
Ta After hot-dip galvanizing of steel structure， it is equivalent to one-time annealing treatment， which can effectively improve the mechanicalof steel matrix，Products Show eliminate the stress during steel forming and welding， and is conducive to turning of steel structure.
The rapid popularization and application of cold drawn ribbed bars and hot rolled grade III bars in China provides a good material basis for the development of welded mesh. The formal implementation of welding net product standards and application procedures has played a positive role in product quality and accelerating popularization and application.
Galvanized pipe is a name for square pipe，San Ignacio35CrMo tube en alliage à paroi épaissePrécautions d'utilisation that is， steel pipe with equal side length. It is made of rolled strip steel after process treatment. Steel pipe has been an essential material in building decoration. Galvanized pipe is also used more in decoration， but hot-dip galvanized steel pipe manufacturers need to know about the size of galvanized pipe and several common sizes of galvanized pipe， which is helpful for your purchase!
l Special rolling method. When it is difficult to roll the required I-beam by the usual rolling method for some reason， the special rolling method can be used to make full use of the skills of uneven deformation and pass design. For example， when the billet section is narrow and wide I-beam is required to be rolled， when the billet is wide and small I-beam is required to be rolled， the negative rolling method can be used Spread rolling，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd etc.
YRelatively high stability and high deformation resistance. The mixture is usually composed of hard fine aggregate graded aggregate with high sand equivalent， especially micro seal and polymer modified seal， which greatly increases the strength and integrity of the pavement.
WTotal quality managementThere are many types of galvanized pipes， mainly including cold plated seamless pipes and hot-plated seamless pipes. But now the previous one is no longer used. The hot-dip seamless tube is still in use. Hot dip galvanized pipe is mainly used for steel pipes with low pressure fluid such as water and gas. When in use， if in normal working environment， the thickness of galvanized layer of hot-dip galvanized seamless steel pipe is up to μ M above， and it has been used safely for about years. It can be seen that its service life is very long. Of course， when purchasing， we should also find regular manufacturers to order. Only in this way can we achieve this service life. As long as the galvanized pipe is cleaned after pickling， it is basically cleaned in ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank. In order to ensure the quality， electro galvanizing will not be used. There are also some small enterprises in the market. They will use electro galvanizing in production. In this way， although it is much cheaper in price. However， the quality is very good when used， and it is also easy to have problems.
lH Quality requirements
According to the data information display information， decoration design， elevator car， handicrafts， household appliances and other industries are closely related to the situation of the real estate industry.
Cold.
Standard requirementsv The weight of seamless pipe is light， and its weight is only one fifth of that of anti steel.
OGB No. I-beam is in height， in leg width and in waist thickness.
Because the zinc coating has excellent ductility， rolling， bending and so on without damaging the coating.
tQuebecWire sleeve: it is also a general carbon steel welded steel pipe. It is used in concrete and various structural power distribution projects. The commonly used nominal diameter is from -mm. The wall of wire sleeve is thin， which is mostly used after coating or galvanizing and cold bending test is required.
zHDefect detection of seamless pipe
Because of this characteristic， seamless pipe is widely used in oil transportation， natural gas natural gas， water and some solid materials transportation. Smooth steel pipe has strong bending advantages compared with other steel pipes. And the smooth steel pipe is also light in weight. It is a very economical single-sided steel.
