Titanium Square Tube
Titanium is an important structural metal developed in the 1950s, and titanium alloy is widely used in various fields because of its high specific strength, good corrosion resistance and high heat resistance. Many countries in the world have realized the importance of titanium alloy materials, have carried out research and development on it, and have been practical applications.
Description
Titanium square tubes has light weight, high strength and superior mechanical properties. It is widely used in heat exchange equipment, such as tubular heat exchangers, coil heat exchangers, serpentine tube heat exchangers, condensers, evaporators and conveying pipelines. Many nuclear power industries use titanium tubes as standard tubes for their units.
Products Description
Titanium square tube is a structural hollow section manufactured from titanium or titanium alloys, characterized by a square or rectangular cross-section. Unlike standard round tubing, square and rectangular profiles offer:
Superior bending stiffness in specific axes
Flat surfaces for simplified welding, bolting, and component attachment
Cleaner aesthetics for architectural and exposed structural applications
Higher packing efficiency for space-constrained assemblies
Titanium square tubes combine the light weight and corrosion resistance of titanium with the structural efficiency of rectangular hollow sections, making them indispensable in aerospace, marine, motorsport, architectural, and high-performance industrial applications.

Titanium square tube, is the general name of square tube and rectangular tube, that is, the side lengths are equal and not equal titanium tube, it is made of titanium through the process of processing, generally is the titanium unwrapped, flattened, crimped, welded into a round tube, and then rolled from the round tube into a square tube, and then cut into the required length, the square tube can be made into straight-seam square tubes and seamless square tubes.

Why Titanium Square Tube?
Choose titanium square tube when:
You need flat surfaces for component attachment or welding
Bending stiffness is required in one axis more than another
Weight reduction is critical and aluminum lacks strength
Corrosion immunity is required and stainless steel is too heavy
Aesthetic appearance matters and must last the life of the structure
You are designing for aerospace, marine, motorsport, or architectural applications where performance justifies the investment
