Galvanized square tube

Galvanized square pipe is a hollow square cross-section steel pipe with a square cross-section shape and size made from hot-rolled or cold-rolled galvanized strip steel or galvanized coil plate, which is formed by cold bending and then high-frequency welding. , or galvanized square rectangular pipes made by hot-dip galvanizing the pre-made cold-formed hollow...
Galvanized square pipe is a hollow square cross-section steel pipe with a square cross-section shape and size made from hot-rolled or cold-rolled galvanized strip steel or galvanized coil plate, which is formed by cold bending and then high-frequency welding. , or galvanized square rectangular pipes made by hot-dip galvanizing the pre-made cold-formed hollow steel pipes.
Classification
Galvanized square tubes are divided into hot-dip galvanized square tubes and cold-dip galvanized square tubes in terms of production technology. 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.
use
Since galvanized square tubes are galvanized on square tubes, the application range of galvanized square tubes has been greatly expanded compared to square tubes. 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.

characteristic

Galvanizing has stronger protective effect and strong corrosion resistance. The entire structure is made of zinc, forming a dense quaternary crystal. This crystal forms a barrier on the steel plate, thus effectively preventing corrosion factors from penetrating. Corrosion resistance comes from the strong protective barrier layer of zinc. When zinc provides sacrificial protection on trimmed edges, scratches, and abraded parts of the coating, the zinc forms an insoluble oxide layer and exerts a barrier protection function.
