A flat elliptical tube—also known as a flattened oval tube or elliptical steel pipe—is a specially shaped metal tube featuring a smooth, flattened oval cross-section. It combines the strength of a round tube with the streamlined design of an ellipse, making it ideal for applications that require aesthetic appeal, high strength, and aerodynamic efficiency.

An elliptical tube, also known as an oval steel tube or elliptical pipe, is a specially shaped metal tubing featuring an elliptical (oval) cross-section rather than the conventional round or square form. Its elegant appearance, superior mechanical strength, and aerodynamic profile make it an ideal choice for both structural and decorative applications.
