Q: What are the storage requirements for SPCC coils?
A: Store in a dry, well-ventilated indoor environment, at least 15cm off the ground, avoiding direct sunlight; stack different tempers/surfaces separately, first-in, first-out.
Q: What are the packaging specifications for sea/land transportation?
A: Steel coils should be wrapped in a moisture-proof paper outer sheath + VCI film + sheet metal binding, with a protective cover on the core; sea transportation requires rust prevention + seawater spray protection, and land transportation requires securing to prevent tipping.
Q: What key parameters need to be specified for export orders?
A: Grade (including temper/surface), thickness × width × coil weight, surface treatment (oiled/oil-free), edge condition (cut edge/rough edge), standard, tolerance grade, packaging and shipping terms.
Q: What are the inspection items for SPCC coils?
A: Chemical composition (spectral analysis), mechanical properties (tensile/hardness), dimensions (thickness/width/diameter), surface (visual inspection + roughness tester), sheet shape (flatness tester), and packaging integrity.
Q: Are SPCC and DC01 interchangeable?
A: Generally interchangeable (composition/performance are similar), but the customer-specified standard needs to be verified; DC01 is based on EN 10130, and SPCC is based on JIS G3141. Tolerances and surface grades need to be confirmed in advance.
