Telspar® “Telescopic” Square Steel Tube
Telespar® is a mild carbon square steel tube, cold formed in 14 ga (.083″), 12 ga (.105″) and 10 ga (.135″) walls. It is produced in such a manner to permit tubular sections to telescope into the next larger size. Telespar® is available in plain (more common) or galvanized finishes (minimum order may apply), with (minimum order may apply) or without holes (more common). Meets ASTM A570, Grade 50; galvanized to ASTM A653 des. G-90. Recommended for structural applications requiring adjustability or reusability, such as racks, hoists, scaffolds, and enclosures. Telespar has excellent weldability properties.
Typical Mechanical Properties:
|Tensile Strength (psi)||52,000 min|
|Yield Point (psi)||33,000 min|
|Elongation (% in 2″)||18-23
(depending upon wall thickness)
