How we work
- Material selection. Tell us the part, the forming steps and the performance target; we recommend the grade and temper and explain the trade-offs.
- Traceability. Each coil is tied to its heat lot and supplied with the original mill test certificate.
- Custom dimensions. Strip is supplied to the thickness and width you specify.
- Response. Quotations and technical questions are answered within one working day.
