Titanium Square Tubing MOQ, Size Tolerance and Bulk RFQ Guide

Titanium square tubing does not have one universal MOQ or standard price per kilogram. A workable quotation depends on grade, outside dimensions, wall thickness, corner geometry, length, tolerance, straightness, twist, surface, production route, quantity, testing and destination. Buyers should provide a drawing or a complete dimensional schedule rather than request only a nominal square size.
Why Titanium Square Tubing MOQ Varies
The minimum quantity may be controlled by available starting material, forming and welding setup, tooling, cut-length yield, heat-lot traceability and the number of different sizes. A common stock-compatible size may be available in a smaller quantity, while a special grade, thin wall, tight corner radius or drawing-specific tolerance may require a production minimum. State both the quantity per size and the total project weight so mixed-size planning can be reviewed.
Dimensions Required for a Reliable Quotation
| RFQ item | What to state | Why it matters |
|---|---|---|
| Outside size | Width × height; confirm square or rectangular form | Controls tooling, starting strip or tube and finished section |
| Wall thickness | Nominal or minimum wall and tolerance | Affects weight, forming, welding, strength and availability |
| Corner geometry | Inside and outside radius, or approved drawing profile | Changes forming severity and usable internal space |
| Length | Mill length, exact cut length or cut schedule | Controls yield, straightness, packing and freight |
| Geometric tolerance | Straightness, twist, squareness and dimensional limits | Determines inspection method and downstream fit-up |
Grade and Specification Boundary
The order must identify the titanium grade and the governing product specification, drawing or approved technical agreement. Do not assume that ASTM B338 round heat-exchanger tube dimensions automatically cover a square section. Mechanical properties and chemistry must be taken from the specification applicable to the ordered grade and product route. If an alternative grade, rectangular section or fabricated route is proposed to reduce cost, it requires engineering and customer approval.
Main Bulk Price Factors
- Grade and starting material: commercially pure and alloy titanium follow different material and processing routes.
- Section and yield: unusual size-wall combinations, many short cuts and tight tolerances increase setup or processing loss.
- Manufacturing route: formed-and-welded, drawing-specific or machined sections have different cost structures.
- Surface and inspection: pickled, polished or drawing-controlled finish plus dimensional reports, PT, UT or other tests must be stated before quotation.
- Packaging and delivery: long lengths, bundle limits, end protection, wooden cases, destination and delivery term affect total landed cost.
Bulk RFQ Checklist
- State square or rectangular form, grade and governing specification.
- Provide outside dimensions, wall, corner radii, length and all tolerances.
- List quantity for every size and estimated total weight.
- Define condition, surface, end preparation and machining allowance.
- Specify tests, MTC, heat traceability, dimensional report and third-party inspection.
- Provide packing limits, destination and required delivery date.

FAQ
What is the MOQ for titanium square tubing?
There is no fixed universal MOQ. It depends on grade, dimensions, wall, corner geometry, tolerance, route, stock or starting material and whether several compatible items can be planned together.
Which dimensions are most often missing from an RFQ?
Corner radii, wall tolerance, straightness, twist, exact cut length and squareness are commonly omitted. A drawing is recommended when the section must fit a mating component.
Can rectangular tubing replace square tubing to reduce price?
Only when the design permits it. Section geometry changes fit-up, stiffness, load distribution and fabrication; any substitution needs engineering and customer approval.
Can several sizes be combined into one bulk order?
They can be quoted as one project, but each size may still have a separate production minimum. Send the full schedule so stock, production and packing options can be evaluated together.
