0.3–3.0mm Annealed Cold Rolled Steel Strip Q195 Q235 DC01 DC03 SPCC with Bright or Black Surface Finish for Forming and Strip Processing

１．Product Overview

Annealed cold rolled steel strips are used for strip processing, forming, bending, stamping, steel furniture, tube making, and industrial fabrication applications.

The product is available with bright surface or black surface finish according to processing requirements. Thickness from 0.3–3.0 mm and width from 35–720 mm support slitting, forming, stamping, and roll forming applications.

Q195, Q235, DC01, DC03, SPCC, SPCD, SPCE, and related grades are supplied for different mechanical performance and forming requirements.

２．Technical Solution

The product is manufactured through cold rolling and annealing processing to improve strip flatness, forming capability, and dimensional consistency.

Continuous black annealing supports stable strip surface appearance and downstream fabrication performance. Mill edge and slit edge conditions are available according to customer processing requirements.

Thickness tolerance of ±0.05 mm and width tolerance of +5 mm/-0 mm support stable strip processing and production consistency.
