Smooth-Bore Seamless Stainless Steel Tubing
Seamless construction with no weld bead gives this tubing an interior with unrestricted flow. It is stronger than welded tubing and can be flared without splitting.
304 stainless steel has very good corrosion resistance.
Tubing that meets ASTM specifications adheres to international standards for dimensions and materials.

Low-Carbon Steel Round Tubes
Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength, such as frames, supports, and conduit. This steel is manufactured to ASTM, SAE, or EN standards for quality and performance.
Heat treatable tubes can be surface hardened.

High-Strength 2024 Aluminum Tubes
- Yield Strength: 42,000 psi
- Hardness: Brinell 120 (Medium)
- Temper: T3
- Fabrication: Cold Drawn
- Specifications Met: ASTM B210
While 2024 aluminum was initially designed for structural components in aircraft, it's now widely used when a high strength-to-weight ratio is needed, such as for gears, shafts, and fasteners. It offers similar performance to 7075 aluminum, but it’s not as strong.

Polished Multipurpose 304 Stainless Steel
Polished to either a brushed or mirror-like finish, this material is widely used to fabricate decorative enclosures and industrial workstations. The sheets, strips, bars, and adhesive-back foil are covered with a protective peel-off film. 304 stainless steel is a good all-around choice for a wide range of applications. It maintains its corrosion resistance in temperatures up to 1500° F.
Mirror-like #7 finish is reflective with some visible grain lines. Rectangular and round tubes are polished on the outside.
