Classification
Galvanized square tubes are divided into hot-dip galvanized square tubes and cold-dip galvanized square tubes from the
production process. It is precisely because of the different processing of these two galvanized square tubes that they have many
different physical and chemical properties. Generally speaking, they have many differences in strength, toughness and mechanical
properties.
Hot-dip galvanized square tube:It is a square tube made of steel plate or steel strip after being crimped and welded. On the basis
of this square tube, the square tube is placed in a hot-dip galvanizing pool after a series of chemical reactions. A square tube formed.
The production process of hot-dip galvanized square tube is relatively simple, and the production efficiency is very high, and there are
many varieties and specifications. This kind of square tube requires very little equipment and capital, and is suitable for the production
of small galvanized square tube manufacturers. But in terms of strength, the strength of this kind of steel pipe is far lower than that of
seamless square pipe.

Since the galvanized square tube is galvanized on the square tube, the application range of the galvanized square tube has been
greatly expanded compared with the square tube. It is mainly used in curtain walls, construction, machinery manufacturing, steel
construction projects, shipbuilding, solar power generation brackets, steel structure engineering, power engineering, power plants,
agricultural and chemical machinery, glass curtain walls, automobile chassis, airports, etc.
