Galvalume (GL / AZ) coil for roofing and solar structure programs — confirm AZ class, thickness, width, and packing on RFQ.
| Property | Value |
|---|---|
| Product | 55% Al-Zn galvalume steel coil (GL) |
| Coating mass | AZ30–AZ150 (project-dependent; AZ150 common for solar structures) |
| Толщина | 0.15–2.0 mm |
| Ширина | 600–1250 mm |
| Surface treatment | Passivation / AFP optional / oiled or dry |
| Steel grades | DX51D+AZ, SGLCC, S250GD+AZ, ASTM A792 CS |
| Standards | ASTM A792, EN 10346, JIS G3321 |
| Coil ID | 508 mm / 610 mm |
| Coil weight | 3–12 t (customizable) |
| Coating composition basis | Nominal 55% Al-Zn alloy-coated sheet; confirm the governing standard and ordered AZ designation |
| GI vs GL boundary | Compare environment, formed-panel design and exposed cut edges; do not infer service life from coating name alone |
| QC checkpoints | Base thickness, width, AZ coating mass, surface treatment and visible surface condition; order-specific forming checks as applicable |
55% Al-Zn galvalume (GL) coil for roofing, cladding, and solar structure programs. Confirm AZ class on the RFQ. Profiled sheets (wave or trapezoidal/IBR) should be specified on the roofing family page and the roofing profiles buyer tool—not as extra near-duplicate GL coil SKUs.
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 base thickness, width, AZ coating mass, passivation or AFP condition and visible surface acceptance in the PO or ITP. GI-versus-GL selection must also consider formed-panel geometry and exposed cut edges; neither coating name nor a generic salt-spray figure is an unconditional service-life guarantee.
Representative export packing and loading evidence. Final packing follows the approved order.
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; Solar mounting and support components after project review; Flashings and formed accessories. Share your end use, environment, and packing needs in the RFQ.
FAQ
It identifies the nominal aluminium-zinc alloy coating family used by standards such as ASTM A792/A792M. The purchase order must still state the governing standard, grade and AZ coating designation.
No. Compare the exposure, formed-panel design, cut-edge condition, downstream painting and project standard. GL performance must not be reduced to an absolute life multiple.
AFP may be specified when handling appearance or downstream processing requires it. Confirm compatibility with forming, bonding or painting before ordering.
State grade and standard, AZ coating, thickness, width, coil limits, surface treatment, forming profile or component use, quantity, packing and destination.
