Stainless Steel Coil ID, Edge & Processing Options
In addition to grade, thickness, width, and surface finish, coil inner diameter, edge condition, and downstream processing are important specifications when sourcing stainless steel coil. HWHG supports different coil configurations and processing requirements to match customers' production equipment and further fabrication needs.
508 mm & 610 mm Coil Inner Diameter
Available stainless steel coil products can be supplied with 508 mm or 610 mm inner diameter (ID) according to the selected product and specification. Choosing the appropriate coil ID helps ensure compatibility with decoiling, slitting, stamping, roll forming, and other downstream production equipment.
Mill Edge & Slit Edge Stainless Steel Coil
HWHG stainless steel coils are available with mill edge or slit edge options according to product and order requirements.
Mill Edge: Retains the original edge produced during rolling and is suitable when further trimming or processing will be carried out by the buyer.
Slit Edge: Produced by precision slitting to achieve the required coil width and a more uniform finished edge for downstream processing.
Buyers should specify the required edge condition when requesting a quotation, especially where coil width and subsequent processing are important.
Stainless Steel Coil Slitting & Custom Widths
For customers requiring narrower or specific coil widths, HWHG supports stainless steel coil slitting based on available production and processing capabilities. Custom width stainless steel coil can be prepared according to the required grade, thickness, width, and downstream manufacturing needs.
Cutting & Surface Processing
Further processing options include cutting, slitting, and surface finishing. Customers can provide their required dimensions, surface condition, and processing specifications so that available options can be reviewed before production.
When requesting stainless steel coil, please specify the required grade, thickness, width, coil ID, edge condition, surface finish, and processing requirements to help us confirm the appropriate supply configuration.
