What kind of steel is galvanized square tube? Specifications and models of galvanized square tube
Galvanized square tube
Abstract: Galvanized square tube is a type of galvanized pipe, mainly made of hot-rolled or cold-rolled galvanized steel strip or galvanized coil as scrap material. The square tube is galvanized, and there are two types: hot-dip galvanized square tube and cold-dip galvanized square tube. It can be used in many fields such as curtain wall, construction, machinery manufacturing, steel construction projects, etc. According to different application scopes and purposes, there are also many differences in the specifications and models of galvanized square pipes.
1、 What is galvanized square tube steel
Galvanized square tube is a type of steel pipe with a square cross-sectional shape and size made from hot-rolled or cold-rolled galvanized steel strip or galvanized coil as raw material, processed by cold bending and high-frequency welding treatment. This is hot-dip galvanized square tube; There is also a type of galvanized square tube made by hot-dip galvanizing pre made cold-formed hollow steel pipes, which belongs to cold galvanized square tubes,. Galvanized square tubes are mainly treated with galvanizing on square tubes, and have a wide range of applications, including curtain walls, construction, machinery manufacturing, steel construction projects, and shipbuilding. Solar power brackets, steel structure engineering, power engineering, power plants, agricultural and chemical machinery, glass curtain walls, automotive chassis, airports and other fields.
