Cold Rolled Steel Foil and Coil
Cold rolled carbon steel strip is the volume workhorse of the Yongxin mill. It reaches 0.035 mm, which is thinner than most general purpose cold rolling lines can hold, and it is annealed and levelled in house so drawing behaviour stays repeatable.
Category Overview
SPCC SPCD and SPCE rolled from 0.035 mm for stamping drawing and converting
Cold rolled steel foil and coil covers carbon steel strip from 0.035 mm to 0.8 mm in widths from 50 mm to 520 mm. The grades are SPCC for general stamping, SPCD for drawing and SPCE for deep drawing, or another grade specified by the customer against GB, DIN, BS, JIS or ASTM.
At these gauges the practical problem is rarely the chemistry. It is whether the strip stays flat, whether the hardness is the same at the tail of the coil as at the head, and whether the surface is clean enough for the next operation. Yongxin controls those variables with continuous and bell type annealing, a degreasing line, a temper mill and a German stretch bending leveller before the strip reaches the slitting line.
The plant also holds an independently verified product carbon footprint for SPCC cold rolled steel strip, which matters increasingly for buyers who have to report supply chain emissions.
Who This Category Is For
- Stamping plants making brackets, clips, shields and enclosure panels
- Deep drawing shops producing shells, cups and housings
- Welded tube and profile makers using narrow slit strip
- Coating, plating and laminating converters
- Appliance and electronics component suppliers
- Service centres re slitting to narrower widths
Problems It Solves
What Goes Wrong With Thin Strip and How We Prevent It
Coil Set and Edge Wave
Strip that will not lie flat jams the feeder and marks the tool. Levelling is a controlled step, not an afterthought.
Hardness Variation Along the Coil
Annealing controlled in house keeps the drawing behaviour the same at the tail of the coil as at the head.
Oil Residue Before Coating
Undegreased strip fails paint adhesion and plating. The degreasing line removes rolling oil before delivery.
Emissions Reporting Gaps
Buyers who must report Scope 3 emissions get a third party verified figure instead of an estimate.
Core Advantages
Why Buyers Specify This Category From Yongxin
Down to 0.035 mm
A gauge band that many general cold rolling lines cannot reach, produced as a routine product.
Deep Drawing Grades in Stock Practice
SPCD and SPCE give the elongation needed for deep drawn shells and housings.
Flatness Set Mechanically
The stretch bending leveller and temper mill set flatness rather than relying on the rolling pass alone.
Clean Degreased Surface
Rolling oil is removed on the degreasing line so plating, painting and adhesive bonding behave predictably.
Verified Carbon Footprint
The SPCC product carbon footprint is verified to PAS 2050 and ISO 14067 at 6296.195 kg CO2e per tonne, cradle to gate.
Slit to Your Width
Slitting lines cut to the ordered width and edge condition so you do not pay for trimming twice.
