PRODUCT SELECTION
A practical comparison.
Start with the tube construction, then match the dimensions and finishing route.
| Product route | Starting material | Size selection | A useful starting point |
|---|---|---|---|
| Precision welded tubes ↗ | Steel strip, formed and high-frequency welded | Thick-wall range: OD 17.3–42.7 mm / wall 1.2–8 mm | Shock absorber tubing, structural and mechanical tube components |
| Cold-drawn welded tubes ↗ | Welded mother tube, subsequently cold drawn | OD 12–78 mm / wall 0.8–8 mm | Steering-system tubes, gas spring tubes and specified machined parts |
| Cold-drawn seamless tubes ↗ | Seamless mother tube, subsequently cold drawn | Send your required OD, wall or ID and length | Mechanical parts requiring seamless tube construction |
Use each product’s size-combination table. The thick-wall range is a specific welded-tube programme; other supplied welded sizes are shown in the application examples. Material, tolerance and delivery condition follow the component specification.
