Square and rectangular titanium tubing -- also known as titanium box sections -- are hollow tubular products with a square or rectangular cross-section rather than a round cross-section. They are produced by forming flat titanium plate or strip and welding the seam, or by drawing through shaped dies. Box sections offer high torsional stiffness and are easier to connect at right angles compared to round tubes, making them preferred for structural framing, guard and handrail systems, machine bases and corrosion-resistant support structures.

Supply is coordinated per inquiry against outer width, outer height, wall thickness, grade and length. The specific production route (welded or drawn) depends on the section dimensions, wall thickness and required quantity.

Grades & Materials

RS

Regular Stock

Grade 1 (CP Ti), Grade 2 (CP Ti). Common sizes and wall thicknesses may be available from mill stock.

CU

Custom Coordination

Grade 5 (Ti-6Al-4V) and other titanium or titanium alloy grades. Production feasibility reviewed per order against section dimensions, wall thickness and forming route.

Standards & Technical References

Square and rectangular titanium tubes have a non-round cross-section. ASTM B338 / B337 are standard specifications for round seamless and welded titanium tubes intended for heat exchanger and process piping service. These round-tube standards do not directly cover non-round cross-sections.

For square and rectangular titanium tubes, applicable requirements are evaluated against the specific product form, production route (welded vs. drawn), grade and order specification. Test standards and tolerance requirements are agreed for each order. Not every square or rectangular section is covered by a dedicated titanium product standard.

Typical Application Areas

FR

Structural Frames & Towers

Titanium box sections for corrosion-resistant frames, machine bases, support towers and load-bearing members where titanium's corrosion resistance reduces maintenance and extends service life.

GR

Guards & Handrails

Lightweight corrosion-resistant guard rails, safety barriers and handrail systems for marine, chemical and industrial facilities.

MH

Marine & Coastal Structures

Titanium box sections for marine structures, offshore platforms and coastal facilities where saltwater corrosion resistance is required.

CH

Chemical Processing Support

Titanium structural members used in chemical plants, plating lines and process equipment support structures where the surrounding environment is corrosive.

Quality & Documentation

  • Material test certificates for titanium plate or strip feedstock.
  • Dimensional inspection reports covering width, height, wall thickness, squareness and straightness.
  • Weld inspection documentation where applicable (for welded production route).
  • Heat or lot traceability records where available and applicable.

Frequently Asked Questions

Are square titanium tubes covered by the same standards as round titanium tubes?

No. ASTM B338 and B337 are standard specifications for round seamless and welded titanium tubes intended for heat exchanger and process piping service. Square and rectangular titanium tubes have a non-round cross-section and are not directly covered by these standards. Applicable requirements are evaluated against the specific product form, production route and order specification.

Which square titanium tube sizes are stocked?

Common square and rectangular sections in Grade 1 and Grade 2 titanium may be available from mill stock. Specific dimensions, wall thicknesses and grades should be confirmed at inquiry time. Non-standard sections and alloy grades are produced to order.

How are square titanium tubes manufactured?

Square and rectangular titanium tubes can be produced by two main routes. The welded route forms flat titanium plate or strip into a rectangular shape and welds the seam. The drawn route pulls a preform through shaped dies to reduce it to final dimensions. The specific route depends on the section dimensions, wall thickness and grade.

Can square titanium tubes be bent, welded or drilled?

Yes. Titanium box sections can be bent, welded, cut, drilled and machined depending on the grade, wall thickness and required operation. Feasibility should be confirmed per inquiry, particularly for tight-radius bending and alloy grades.
