JIS G 3141 SPCC / SPCD / SPCE Cold Rolled Steel Strip With Mill Edge & Slit Edge

JIS G 3141 SPCC / SPCD / SPCE Cold Rolled Steel Strip With Mill Edge & Slit Edge

1．Product Overview

Cold rolled steel strip is suitable for downstream processing where controlled thickness range, narrow width production, and stable strip geometry are required. This specification covers JIS G3141 SPCC SPCD SPCE and related equivalent grades, with mill edge and slit edge options for different processing routes.

The product range is focused on strip applications rather than wide cold rolled coil. With 0.3–3.0mm thickness and 30–720mm width, it is suitable for further slitting, forming, stamping, and general sheet metal fabrication where narrow-width cold rolled material is needed.

2．Technical Solution

The product is supplied as annealed cold rolled steel strip with brightness or black surface finish. Edge condition can be selected as mill edge or slit edge according to downstream processing requirement. These details matter in actual use because strip width, edge condition, and surface finish affect forming route, trimming allowance, and handling method.

For applications requiring narrower widths, slit edge is commonly used. For routes where original edge condition is acceptable, mill edge can be selected. The available standards and grade system also allow matching to general commercial forming and drawing-related cold rolled strip use.

4．Application

This material is suitable for narrow-width cold rolled strip processing where stable strip dimensions and selectable edge condition are required.

It can be used for further slitting, bending, forming, stamping, and general fabricated strip components.

It is also suitable for applications where brightness finish or black surface finish is specified according to the downstream route.

5．Processing

• The strip can be supplied with mill edge or slit edge according to processing requirement.
• It is suitable for recoiling, slitting, cut-to-length conversion, bending, and general forming.
• Width selection should be matched to the final blank size, tooling route, and scrap control target.

6．Advantages

• The 30–720mm width range is suitable for cold rolled strip applications requiring narrower coil width.
• The 0.3–3.0mm thickness range covers light to medium strip processing requirements.
• Mill edge and slit edge options allow different downstream processing routes.
• Brightness and black surface finish options provide flexibility for different fabrication conditions.
• The grade system includes JIS, EN, DIN, GB, and SAE equivalents, which helps match different market and project requirements.

7．How to Choose

• Choose SPCC for general commercial cold rolled strip use.
• Choose SPCD or SPCE when the downstream route requires better forming or drawing performance.
• Choose slit edge when final narrow-width processing and edge control are important.
• Choose mill edge when original edge condition is acceptable in the downstream route.
• Choose thickness and width together according to the final part geometry, tooling condition, and forming requirement.
