brief introduction

Galvanized square pipe is formed on the basis of the processing of the square pipe, galvanized square pipe is mainly formed by the processing of the square pipe galvanized processing. Thus forming galvanized square pipe. This kind of pipe is also different in processing technology, which is divided into cold galvanized square pipe and hot galvanized square pipe. Cold galvanized square pipe is actually a square pipe formed by galvanizing in the way of electric galvanizing.

Processing technic

The main principle is the use of zinc filler coating, in the use of any coating method to coat the protected surface, after drying to form a zinc filler coating, in the dry coating has a zinc content (up to 95%). At the same time point galvanized square pipe is also one of the main components. Electrogalvanizing has a great improvement in its stability and galvanizing amount than the coating type.

Coating cold galvanizing

This cold galvanized square tube is mainly coated with zinc coating material on the surface of the square tube, which will form a coating with metal zinc on the surface of the square tube, which can largely isolate the contact between the square tube and the outside world, and effectively avoid the corrosion of the atmospheric tube. However, its disadvantage is that because it is coated galvanized, the galvanized layer is not very stable and easy to scratch and knock off. But it also has its advantages and convenience. Because once the damage is found, we can use paint to repair the damage without re-galvanizing. This is unmatched by other galvanized square pipes.

Electroplating cold galvanizing

The galvanized square pipe produced by this method is the most important product in cold galvanized square pipe. Because this galvanizing method has the characteristics of low production cost, easy operation, and stable galvanizing layer. This is also the reason why many of our galvanized square pipe manufacturers fancy this galvanized square pipe.

The principle of electrogalvanizing is mainly based on the process of forming a uniform, dense and well-combined metal zinc deposit layer on the surface of the workpiece by electrolysis. The zinc layer generated by this galvanizing method is relatively stable and is not easy to fall off, which gives this cold galvanized pipe a great bonus in corrosion resistance. The problem of stability of zinc layer by other cold galvanizing methods is effectively solved.

Product purpose

There are many applications of cold galvanized pipes in our lives, including construction, machinery manufacturing, steel construction projects, shipbuilding, solar power generation supports, steel structure engineering, power engineering, power plants, agriculture and chemical machinery, glass curtain walls, automobile chassis, airports, boiler construction, highway railings, housing construction and so on.
