Aluminum tube has three actual class/OD/wall combinations, not a complete1×1inch square profile. The requested6061T6 and ASTM B221 scope need actual records.

Define shape and feasible section

Square shape and Round Extrusion Pipe type are both referenced. Specify both legs, wall, bore and corners rather than treating3–250mm OD labels as square geometry.

• 6061/6063 models.
• Small/medium/large classes.
• 0.3–50mm actual wall range.
• 0.3–5mm body wall reference.
• 6m/custom length.

Select actual condition

O–H112 and Full Hard require alloy/temper clarification. Al98.8% is not a universal certified composition for every listed grade.

Agree fabrication acceptance

Request actual drawing, material and dimensional tests. Construction context does not establish strength, approved joints, pressure suitability or structural capacity without selected-profile evidence.
