30*50 Pre Galvanized Square Steel Tube

Seamless square steel tube is manufactured based on seamless round pipe after cold forming to be square steel tubing. Seamless square hollow section is widely used in machine manufacturing, construction, metallurgical industry, agricultural vehicle, greenhouse, railway, furniture and other steel construction. The main application of S355JRH Seamless Square Steel Tube is that transporting routes for gas, oil, chemical materials, water, steam and other gas or liquid.

Seamless square tube is a hollow section surrounding no juncture of strip steel. Tube is hollow, has set a certain cross-sectional area, a large number of used for conveying fluid tube, such as oil, natural gas, coal gas, water and some solid materials, such as tube lines, circle cross section under radial pressure, the internal or external stress is relatively uniform. Therefore, the vast majority of square steel tube is round tube. But round tube also has some limitations, such as in the plane bending condition, the tube is not square, rectangular tube bending strength is big. Some agricultural machinery and skeleton rectangular tube and steel wood furniture is commonly used. Seamless square tube is also used in making mechanical equipment, solar energy equipment, steel structure, auto parts, bridge pile, guardrail and ship's internal structure.
