Q: What are the storage requirements for SPCC cold-rolled coil?
A: ① Store in a dry, ventilated warehouse with relative humidity below 60%; ② Keep away from corrosive substances such as acids and alkalis; ③ Regularly inspect bare coils to prevent rust; ④ Coils should be stored vertically to avoid squeezing and deformation.
Q: What precautions should be taken when transporting SPCC?
A: ① Cover with waterproof tarpaulin to prevent rain damage; ② Use cushioning material to separate coils to prevent collisions and scratches; ③ Manage vibrations during transportation to prevent deformation of the coil core.
Q: Will oiled SPCC coils bleed during storage?
A: Slight oil bleed may occur at higher temperatures. This is normal and does not affect the material's performance. Wipe clean before use.
Q: What is the typical shelf life of SPCC?
A: Bare coils can be stored in a dry environment for 3-6 months. This can be extended to 12 months after oiling or laminating, depending on storage conditions. Q: What treatment is required for reusing SPCC coils after long-term storage?
A: Check the surface for rust. Minor rust can be removed by grinding. Severe rust will affect subsequent processing and require annealing if necessary.
