Hot-dip galvanized (GI) coil and sheet for roofing, cladding, ducting, and fabrication. Specify coating mass, grade, and surface on the RFQ. Need narrow widths? Order slit strip from the strip family instead of a duplicate GI SKU. Downstream color-coated demand should move to the PPGI / PPGL hub with paint system and RAL. Comparing Al-Zn service life? Open the GL family and GI vs GL buyer guide before locking the PO.
Write surface, profile, and strip width into the RFQ and tools—not extra near-duplicate product pages.
RFQ documents & delivery
Packing, MTC, and inspection path — include them in your RFQ for an actionable quote.
Agree the PO or ITP checkpoints before production. Applicable GI checks cover base thickness, width, zinc coating mass, surface and spangle condition, plus adhesion or bend performance when the forming route requires it. Document type, sampling and acceptance limits remain order-specific until approved records are on file.
Supply confidence
Fixed delivery proof plus this product’s applications — confirm stock, inspection, and end use before RFQ.
Strapped coils and plates staged by lot so grade, thickness, and destination port can be matched quickly for shipment.
Overseas buyers and third-party inspectors are welcome to verify specs, heat numbers, and packing. SGS/BV support available.
Typical uses for this product: Roofing and wall-cladding roll forming; HVAC ducting and cable-tray fabrication; General sheet-metal fabrication and formed components. Share your end use, environment, and packing needs in the RFQ.
FAQ
Z275 is a coating-mass designation used with the governing product standard. State the standard and designation together because reporting basis and tolerances must follow that document and the accepted order.
Use the strip family when the finished slit width, width tolerance, edge condition or narrow-coil packing is a purchasing requirement. Use this page for full-width coil or cut sheet.
Match regular, minimized or zero spangle and passivated, Cr-free, oiled or dry treatment to appearance, forming and storage needs. Put the selected combination on the RFQ and PO.
Agree dry handling, passivation or oil where applicable, moisture-barrier wrapping, edge protection, storage conditions and destination climate before packing release. No packing duration is guaranteed without an approved order basis.
Confirm with sales against grade, coating mass, dimensions, coil weight, quantity and the current production schedule. This page does not publish an unconditional MOQ or lead-time promise.
