Mill & Slit Edge JIS G3141, SPCC, SPCD, SPCE, EN10130, GB Cold Rolled Steel Strip / Strips

1．Product Overview

Cold rolled steel strip is suitable for narrow-width processing where controlled thickness, stable strip geometry, and selectable edge condition are required. This product range is supplied under JIS G3141, EN10130, DIN1623, GB/T 700, and SAE grade systems, with thickness from 0.3–3.0mm, width from 30–720mm, coil ID 508mm, and coil weight up to 7 MT.

2．Technical Solution

The strip is supplied with annealed surface shape in brightness finish or black surface finish, and can be produced with mill edge or slit edge according to downstream processing requirement. In actual use, strip width, edge condition, and surface finish directly affect trimming allowance, recoiling, profiling, and stamping route selection.

3．Specifications

4．Application

• This material is suitable for narrow-width cold rolled strip processing where dimensional control and selectable edge condition are required.
• It can be used for recoiling, slitting, bending, profiling, stamping, and general fabricated strip components.
• It is also suitable for applications where brightness finish or black surface finish is selected 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.
• Thickness and width should be selected together according to final part geometry, tooling condition, and strip utilization target.

6．Advantages

• The 30–720mm width range is suitable for strip applications requiring narrower coil width rather than wide sheet.
• The 0.3–3.0mm thickness range covers light to medium cold rolled 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 according to the final part geometry, tooling route, and forming requirement.
