Ordering this size
Also written as 3-1/2 inch DOM tube with 0.250 wall. The first number is the outside diameter, not the bore or a nominal pipe size.
For this combination, nominal ID = 3.500 − (2 × 0.250) = 3.000 inches. Check actual ID tolerances and mating-part dimensions for fits.
A nominal 6-foot piece has an estimated material weight of 52.14 lb, before packaging. This is an estimate, not a shipping charge.
Dimensions are nominal. Weight is theoretical, calculated with steel density 0.2836 lb/in³; actual weight and dimensions vary. Confirm specification, grade, tolerances and documentation in the written quote.

Before you order
For machining allowances, telescoping fits or a specified bore finish, include the drawing requirements. Mechanical properties depend on grade and condition. For structural or safety-critical applications, use the material and dimensions required by the applicable design specification.
