Galvanized square tubes are divided into hot-dip galvanized square tubes and cold-dip galvanized square tubes from the production process.

Hot-dip galvanised square tube: it is a square tube that is welded after being rolled and shaped using steel plates or steel strips, and on the basis of this square tube, it is placed in a hot-dip galvanised pool and formed again after a series of chemical reactions.

The cold galvanized square tube uses the principle of cold galvanizing on the square tube used to make the square tube anti-corrosion. Anti-corrosion is mainly carried out by electrochemical principles, so it is necessary to ensure sufficient contact between zinc powder and steel to generate electrode potential difference, so the surface treatment of steel is very important.

Generally speaking, they have many differences in strength, toughness and mechanical properties.

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.
