Telespar Mechanical Tubing

We maintain a large inventory of Telespar square tubing sizes, gauges and finishes in our warehouse so that we can provide you with fast delivery on whatever style of square steel tubing you need. Unlike Telespar telescoping tubing specifically for sign post applications, mechanical tubing includes square tubing without holes (solid steel square tubing) and plain carbon steel ("black" steel) finish (unfinished). Carbon steel telescopic tubing is lightly oiled to inhibit rust.

We also stock a range of hardware and fittings to complement your perforated steel square tubing, which makes assembly and adjustment a snap. We've got everything you need for your project under one roof. We can even cut and fabricate to meet your requirements!
