Can heat treatment be included?

Heat treatment can be selected according to the grade, standard and required mechanical properties. The exact condition must be confirmed on the order.

Is the tube ready for bending and welding?

The delivery condition can be selected for the intended fabrication route, but the buyer must validate bend radii, tooling, welding procedure and final structural performance.

What information is needed for quotation?

Material grade, standard, OD, wall thickness, length, tolerance, heat-treatment condition, surface, tests, quantity and drawing when available.
