Hot Finished Elliptical Hollow Sections - 150x75x4.0
Hot-finished elliptical hollow sections are oval-shaped steel tubes manufactured at very high temperatures to create a smooth, continuous profile. Because they are shaped while the steel is red-hot, they are free from internal stresses, which makes them highly reliable, easy to weld, and resistant to cracking. Their unique egg-like shape combines the high twisting resistance of a round pipe with the superior bending strength of a rectangular tube along its wider axis. This efficient structural performance, paired with an elegant and modern appearance, makes them a popular choice for high-end architectural features, feature columns, and exposed steel frameworks.
