This type of connection is composed of two tubes connected by bolts to an inner tube with a smaller diameter, and explores the efficiency, aesthetics and resistance of hollow sections subjected to tension and compression.
Steel tubing is used in residential and commercial buildings. Stairways and railings are made from tubular steel, and it is also used in support structures, roofs and ceilings. Architects use tubular steel both for its functional and decorative qualities.
Tubular steel sections are naturally strong, especially against longitudinal stress, which is why steel tubes are used in applications like scaffolding. Steel tubing and pipes are particularly resistant to length ways compression, but still offer better resistance against bending forces than flat sheet steel
