Stainless Steel Coil
Stainless steel coil is supplied in multiple grades and surface finishes to meet corrosion, formability and strength requirements across industrial, architectural and process applications. Jialu Metal holds a broad stock of coil across the 200, 300, 400 and duplex series, so a project requiring 304L for food processing, 316L for marine exposure and 430 for exhaust components does not need to be split across three mil
- Multiple stainless steel series available on one stock list: 200, 300, 400 and duplex, so mixed-grade projects stay on one order
- Surface finishes from 2B, BA, 4K to embossed and custom patterns, reducing need for secondary processing
- Thickness range from 0.12 mm to 6.0 mm covers thin sheet for forming and thick plate for structural use
- Standard coil sizes (508 mm and 610 mm ID) with 3 to 5 tonne weights support efficient handling and cutting
Mill certificates issued against the ordered grade and standard. Third-party inspection available on request.
What This Material Is For
Stainless steel coil is supplied in multiple grades and surface finishes to meet corrosion, formability and strength requirements across industrial, architectural and process applications. Jialu Metal holds a broad stock of coil across the 200, 300, 400 and duplex series, so a project requiring 304L for food processing, 316L for marine exposure and 430 for exhaust components does not need to be split across three mills or three inspection cycles. The coil is available in thicknesses from 0.12 mm to 6.0 mm, widths up to 1500 mm, and standard inside diameters of 508 mm and 610 mm, with full customization available on request.
Why Buyers Choose It
- Multiple stainless steel series available on one stock list: 200, 300, 400 and duplex, so mixed-grade projects stay on one order
- Surface finishes from 2B, BA, 4K to embossed and custom patterns, reducing need for secondary processing
- Thickness range from 0.12 mm to 6.0 mm covers thin sheet for forming and thick plate for structural use
- Standard coil sizes (508 mm and 610 mm ID) with 3 to 5 tonne weights support efficient handling and cutting
- Third-party inspection can be arranged at order stage, avoiding delays after shipment
Where It Is Used
- Food and beverage processing equipment requiring 304L and 316L with sanitary surface finishes
- Marine and offshore components using 316L and 2205 duplex for chloride resistance
- Architectural cladding and roofing using 430 and 304 with HL or embossed finishes
- Chemical and petrochemical piping systems using 310S, 316Ti and 904L for high-temperature and corrosive service
- Automotive exhaust systems using 409L and 439 with high-temperature oxidation resistance
- Industrial machinery and equipment using 410, 416 and 430 for wear and moderate corrosion
Who It Is For
- Fabricators sourcing mixed-grade stainless coil for one project scope
- Equipment manufacturers needing multiple surface finishes and thicknesses on one purchase order
- Contractors building marine or chemical plants requiring corrosion-resistant materials across multiple zones
- Architectural suppliers sourcing coil with specific finishes for façade and interior applications
- Industrial buyers who want to avoid splitting orders across multiple suppliers for inspection and logistics
Problems It Solves
- Splitting one coil scope across multiple mills due to limited grade or surface availability
- Delays caused by waiting for multiple inspection reports from different suppliers
- Inconsistent surface quality when sourcing from different vendors for the same project
- Lack of standard coil sizes and weights leading to inefficient handling and cutting
- Inability to get mixed grades and finishes on one order, forcing multiple shipments
Technical Features

- Surface finishes include BA, 2B, 2D, 4K, 6K, 8K, NO.4, HL, SB, embossed, and custom options
- Thickness range: 0.12 mm to 6.0 mm, suitable for thin forming and heavy-duty structural use
- Width range: 600 mm to 1500 mm, covering standard and wide-format applications
- Coil inside diameter: 508 mm or 610 mm, with weights between 3 and 5 tonnes per coil
- Surface treatments: chromed, skinpass, oiled, slightly oiled, dry, or as specified

How It Compares With The Alternatives
| Hot-rolled stainless plate | Hot-rolled plate has rougher surface and less dimensional control; coil is better for forming and machining applications |
|---|---|
| Single-grade coil from a narrow supplier | Single-grade suppliers force buyers to split orders; Jialu allows mixed grades and finishes on one order |
| Local warehouse coil | Local stock may lack duplex or specialty grades; Jialu offers global-grade availability with export-ready logistics |
Buying Guide
- Start with the application environment (corrosive, high-temp, forming) to narrow the grade family
- Specify the required surface finish early—BA, 2B, HL or embossed—so the correct processing is applied
- Send thickness, width and coil ID requirements with the enquiry, as availability varies by size
- For high-temperature or chloride service, state the environment so 310S, 316Ti or 2205 can be quoted
- Book third-party inspection at order stage to avoid delays after shipment
