SPCC SD Cold Rolled Steel Coil

Core advantages of products

High strength and precision processing performance

Full hard steel coils are made by cold rolling process from hot-rolled pickled coils, with a hardness of more than HRB 90, a smooth surface, and a precise thickness tolerance (±0.02mm), suitable for precision processing such as laser cutting and punching13.

SPCC series: Complies with JIS G3141 standard, with moderate carbon content, widely used in general fields such as structural parts and housings12.

DC01-DC03 series: Complies with EN 10130 standard, low-carbon design improves stamping ductility, especially suitable for automotive parts and complex molded parts1213.

Diversified specifications and customized services

Thickness range: 0.17mm-3.5mm (supports ultra-thin plate customization)13

Width selection: 600mm-1500mm, can be cut to customer required size in strips

Surface state: full hard state (rolled hard coil), annealed state optional, adapted to the needs of different processing stages

Cost-effectiveness and environmental protection characteristics

Fully hard steel coils can be directly used for simple bending or galvanized substrates without annealing, reducing processing energy consumption; Secondary Quality steel coils provide cost-effective options to reduce material waste13.
