The production process of hot-dip galvanized square pipe is relatively simple, and the production efficiency is very high, the varieties and specifications are also many, and the equipment and funds required for this kind of square pipe are very little, which is suitable for the production of small galvanized square pipe manufacturers. However, in terms of strength, the strength of this steel pipe is far lower than that of seamless square pipe.

Hot-dip galvanized square tube: It is a square tube welded after the use of steel plate or steel strip crimping, and on the basis of this square tube, the square tube is placed in the hot-dip galvanized pool after a series of chemical reactions.

Galvanized coil, the thin steel plate is dipped into the melted zinc tank, so that its surface adheres to a layer of zinc thin steel plate. It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously dipped in the plating tank with melted zinc to make galvanized steel plate. Alloyed galvanized steel sheet. This steel plate is also made by hot dipping, but immediately after the tank is heated to about 500 ° C, so that it generates an alloy coating of zinc and iron. This galvanized coil has good coating adhesion and weldability.

Because galvanized coil has the characteristics of strong corrosion resistance, good surface quality, conducive to deep processing, economic and practical, it is widely used in construction, home appliances, automobiles, containers, transportation and home industry and other fields. Especially steel structure construction, automobile manufacturing, steel silo manufacturing and other industries.

Galvanized coiled sheet is a thin steel sheet that is immersed in a molten zinc bath so that a layer of zinc adheres to the surface. At present, the continuous galvanizing process is mainly used for production, that is, the rolled steel plate is continuously immersed in a plating bath containing molten zinc to make galvanized steel plate; alloyed galvanized steel plate.
