Third-Party Inspection Support: We support and facilitate pre-shipment quality verification by SGS, TUV, or BV at our facility. Flexible Order Volumes (MOQ): Minimum order quantities starting from 1 to 2 Metric Tons for standard grades to support trial runs. Fast Lead Times: Standard stock grades are ready for dispatch within 7–10 days. Custom slitting/processing orders are fulfilled within 15–25 days. Heavy-Duty Export Packaging: Vertical or Horizontalpackaging options. Moisture-resistant kraft paper, desiccant packs, robust inner/outer steel rings, and heavy fumigation-free wooden skids. Ensured stability in shipping containers to prevent shifting or telescoping during sea transit. Frequently Asked Questions (FAQ) Q: Can you slit the master stainless steel coils into narrow strips? A: Yes. We have advanced high-speed slitting lines that can slit wide coils into precise narrow strips (down to 10mm width) with minimal burr and tight width tolerances. Q: Which packing method is better: "Eye to Sky" or "Eye to Wall"? A: "Eye to Sky" (vertical) packaging is generally preferred for lighter coils as it simplifies forklift handling. "Eye to Wall" (horizontal) packaging is highly recommended for heavier coils (above 5 tons) to prevent coil deformation during long-distance maritime shipping. Let us know your factory's lifting equipment specs, and we will package accordingly. Q: How do you protect the coil surface from scratches during processing? A: We can apply high-quality single or double-layer PVC/Laser protective film on the surface of the coil during the recoiling process. This ensures the material remains pristine during your subsequent stamping or bending processes. Q: What payment terms do you support for international B2B orders? A: We typically work with T/T (Telegraphic Transfer) and irrevocable L/C (Letter of Credit) at sight.
