Galvanized square steel tubes have excellent comprehensive mechanical properties, stable performance and excellent quality. The main reason for the wide application of galvanized rectangular pipe is that it can play more advantages in the use process and meet the needs of more industries. It can show better corrosion resistance when the service quality is very stable, so don’t worry about the quality risk.
Square tubes are classified according to their cross sections:
(1) simple square tubes—square tubes and rectangular frame square tubes;
(2) complicated square tubes—flower-shaped square tubes, open-mouthed square tubes, corrugated square tubes and special-shaped square tubes. Classification of metal surface treatment of galvanized square tubes: according to metal surface treatment, square tubes are divided into hot-dip galvanized square tubes, phosphatized square tubes, oiled square tubes and pickling passivated square tubes.
Classification of main uses of galvanized square tubes: Square tubes are classified according to their main uses-square tubes for decoration and design, mechanical equipment, industrial grade square tubes for mechanical equipment, square tubes for chemical plants, steel frame structures, square tubes for shipbuilding industry, square tubes for trolleys and square tubes for steel columns and beams.
Classification of wall thickness of galvanized rectangular tubes: rectangular tubes are classified according to wall thickness-ultra-thin-walled rectangular tubes, thin-walled rectangular tubes and thick-walled rectangular tubes.
Galvanized square steel pipes are mainly used in curtain wall, architecture, machinery manufacturing, steel construction projects, shipbuilding, solar power generation support, steel structure engineering, power plant, agricultural and chemical machinery, glass curtain wall, automobile chassis, airport, etc.
