Telescoping Square Tubing with or without holes, can be used for almost any application: racks, shelving, ceiling grids, conveyor systems, interior partitions, adjustable platforms, material handling devices, scaffolds, strapping machines, hangers, support members, protective railings, sign supports, etc.
The secret to Telescoping Square Tubing versatility is its ability to telescope, allowing smaller sizes to fit smoothly and snugly into the next larger size. This is made possible by high-speed roll forming technology with high-frequency resistance welding. This produces smooth corner welds within very close tolerances, reducing your fabrication costs.
Telescoping Square Tubing comes in five sizes, from 1-1/2″ to 2 – 1/2″ square.
Perforated holes are 7/6″ and spaced on 1″ centers. Sections without holes are available.
Telescoping Square Tubing is galvanized per ASTM A -653 G-90, then receives a conversion coating and a clear organic topcoat to prevent rust and corrosion.
