Cold Rolled Mild Steel Coils

Cold rolled mild steel coils undergo an additional rolling process at room temperature after initial hot rolling, compressing the steel further to achieve tighter tolerances, a smoother surface, and improved mechanical properties. Work hardening during cold reduction increases yield strength and improves fatigue resistance, producing a material that holds up better under repeated loading than hot-rolled equivalents of the same thickness.

This combination of tighter thickness tolerances, higher strength-to-weight ratio, and a clean surface finish makes cold rolled coils the standard choice for applications where the material needs to perform structurally and aesthetically at the same time. As a trusted steel supplier in the Philippines, Metal Exponents supplies cold rolled mild steel coils to architects, contractors, and fabricators who need a product that performs to spec from the first piece to the last.

JIS G3141 SPCC-SD

JIS G3141 SPCC-SD

A commercial-quality cold rolled mild steel produced with a skin-passed dull finish, SPCC-SD is the preferred specification for projects where surface consistency and formability are driving the material decision. The skin-passing treatment applies a light final roll that refines surface texture, eliminates yield point elongation, and produces a finish uniform enough to serve as a base for electrogalvanizing, powder coating, or direct paint application without additional surface preparation.

Its low carbon content and tightly controlled chemical composition allow the grade to undergo deep drawing and bending operations repeatedly without cracking or surface failure. The low sulfur and phosphorus levels contribute to cleaner weld seams and reduced porosity, making SPCC-SD reliable for fabricators who weld after forming rather than before.
