Typical applications
Below is where this material actually ends up — the specific parts, not just the industry. Compare it with your own service conditions, or send us the environment and we will advise.
- Vessel heads — blanks for elliptical and dished heads
- Tank ends — storage, fermentation and water tank end caps
- Large vessels — one-piece end plates in the 1–2 m range
Selection FAQ
- What does head stock require?
- Good ductility and uniform thickness tolerance — usually 304 / 316L. The material is subsequently spun or pressed, so negative thickness deviation must be held tighter than for ordinary sheet.
- Can you supply over-width?
- Beyond standard width it needs welding or a wider feedstock; send the head diameter and forming process for assessment.
