Differences between SPCC, DC01, DC03, DC04, and ST12 cold-rolled coil grades: How to choose

Shanghai Biying International Trade Co., Ltd. explains the differences and selection methods for cold-rolled coil grades: SPCC, DC01, and ST12 are standard-grade coils suitable for general forming, bending, and simple stamping; DC03 is a drawing-grade coil for shallow drawing; DC04 is a deep-drawing grade for complex sheet metal and deep-stamping automotive parts; DC05/DC06 are extra-deep-drawing grades for high-difficulty stretching. We stock all grades and provide professional material selection support to recommend the best fit for your processing needs. Contact us today.
