A: SECC is SPCC with electroplated zinc, significantly improving corrosion resistance. It is used in high humidity or outdoor applications and is more expensive than SPCC.
A: 100% recyclable, a green material. Recycled materials can be remelted for cold or hot rolling production, meeting the requirements of a circular economy.
A: For long-term stable demand, use futures to lock in prices; for small batches/urgent orders, choose spot goods, carefully check the material certificate and surface condition, and prioritize resources from well-known steel mills.
