7 MT 35 - 720MM DIN1623 ST12 / ST13 / ST14 Cold Rolled Steel Strip With Mill & Slit Edge

7 MT 35 - 720MM DIN1623 ST12 / ST13 / ST14 Cold Rolled Steel Strip With Mill & Slit Edge

1．Product Overview

Cold rolled steel strip is used where narrow-width material and controlled strip thickness are required for downstream processing. Compared with wider cold rolled coil or sheet, strip material in the 30–720mm width range is more suitable for slitting, profiling, bending, stamping, and general fabricated strip components. The product can be supplied with brightness or black surface finish and with mill edge or slit edge according to the processing route.

2．Technical Solution

The strip is supplied under JIS G3141, EN10130, DIN1623, GB/T 700, and SAE grade systems, which allows matching to general commercial forming and drawing-related applications. Surface condition and edge condition are part of the functional specification because strip width, edge type, and annealed finish directly affect downstream trimming, recoiling, and forming performance. Coil build is controlled with max. 7 MT coil weight and 508mm coil ID for standard strip handling and processing.

3．Specifications

4．Application

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

It can be used for further 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 manufacturing 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.
