Use the Telespar System to fill your building needs in 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. No special welding, tools or assembly procedures are necessary with the Telespar System.
One of the secrets to Telespar’s versatility is its ability to telescope. Smaller sizes fit smoothly and snugly into the next larger size. This is made possible by the latest in high-speed roll-forming technology with high-frequency resistance welding. This produces
smooth corner welds within very close tolerances, reducing your fabrication costs. Telespar standard perforated tubing comes in eight sizes, from 1″ to 21⁄2″ square, in 10 and 12 gauge. Perforated holes are 7⁄16″ spaced on 1″ centers, except for 1″ and 11⁄4″
which have 11⁄ 32″ holes on 1″ centers. Sections without holes are available in all sizes.
Telespar comes in two standard finishes: Pre-Galv Plus™ and plain (lightly oiled) surface. The Telespar System includes a complete line of zinc-electroplated fittings, fasteners and accessories for splicing, extending and reinforcing.
Tubing shall be TELESPAR® tubing conforming to manufacturers’ standards. Tubing shall be corner welded by high-frequency resistance welding and externally scarfed to agree with corner radii.
Tubing with plain finish is roll formed from 10 gauge (.135) and 12 gauge (.105 U.S.S. Gauge) hot rolled steel, ASTM Des. A-1011 Grade 50, pickled and oiled. Galvanized finish, roll formed from 10 gauge (.135) and 12 gauge (.105 U.S.S. Gauge) hot rolled steel, galvanized material ASTM A-653 Grade 50. Average minimum yield strength after cold forming is 60,000 PSI.
Plain – Material has oiled finish as the material comes from the rolling mills. Tubes must be thoroughly cleaned before protective finishes are applied.
Pre-Galv Plus™ – Galvanized conforming to ASTM specification A-653 des. G-90. Corner weld is zinc coated after scarfing operation. Tubing then receives a conversion coating and a clear organic polymer topcoat.
