Titanium Square Hollow Section are high-performance structural components manufactured from high-purity titanium (GR1/GR2) or titanium alloys (such as GR5) using advanced hot extrusion and precision cold rolling processes. Featuring a uniform closed-section design, these profiles offer exceptional structural integrity, meeting the critical load-bearing requirements of both aerospace systems and industrial equipment where corrosion resistance, mechanical reliability, and long-term durability are essential. With excellent weldability and machinability, they are widely used in the fabrication of aircraft and spacecraft structures as well as high-end industrial assemblies.

These profiles maintain stable performance under extreme environmental conditions, including temperatures ranging from -70°C to 300°C. Their surface passivation layer provides outstanding chemical inertness, while optional surface treatments-such as pickling, sandblasting, and polishing-allow customization to meet the specific standards of aerospace and industrial sectors. Combining material excellence, precision engineering, and long service life, titanium square profiles integrate seamlessly into advanced applications such as satellites, marine systems, precision machinery, chemical reactors, and medical equipment.
