Application:
Used in the general structure and the mechanism, including construction, machinery, transportation, aviation, petroleum mining and each kind of structural tubes.
In structural engineering, the tube is the system where in order to resist lateral loads (wind, seismic, etc.) a building is designed to act like a hollow cylinder, cantilevered perpendicular to the ground.
