Telescoping Square Tubing

Telescoping square tubing is extremely versatile because smaller sizes fit smoothly and snugly into the next larger size. This telescoping functionality is made possible by the latest in high-speed roll-forming technology with high-frequency resistance welding. The resulting products have smooth corner welds within very close tolerances, reducing your fabrication costs.

For industrial and commercial applications, telescoping square tubing is an adaptable, versatile and durable solution.

Unistrut Service Company offers two brands of telescoping square tubing: Telespar and Telestrut. Telestrut is compatible with Unistrut channel and fittings. Telespar is well suited for a variety of industrial applications, but it does not pair with Unistrut channel. Shop Telestrut and Telespar products below, or contact a Unistrut specialist for design and engineering support.
