Mild Steel Hollow Sections For Building Material
Product origin :Tianjin, China
Steel hollow section can be mainly divided into round hollow section, rectangular hollow section and square hollow section.
Rectangular and square carbon steel tube are widely used in various fields such as construction or building, low pressure liquid delivery, engineering, fencing,greenhouse etc.
Surface of steel hollow section generally are black or galvanized, galvanized Steel tube has good features of corrosion resistance, anti-rust, acid resistance, which largely extend its service life.
