AZ150 G550 AFP Galvalume steel coil for roofing-sheet and roll-forming orders. Confirm the standard, dimensions, anti-fingerprint treatment, forming route and export packing per order.
The AZ150 G550 AFP hot-dipped Galvalume GL steel coil request is intended for buyers preparing roofing-sheet or roll-forming orders. Galvalume, aluminium-zinc coating, AZ150, G550 and AFP are separate order requirements. Confirm the final standard, dimensions, surface treatment, forming route, quantity and packing per order.
AZ150 identifies the requested aluminium-zinc coating class, while G550 identifies the requested high-strength grade. List them separately so the supplier can review the correct combination. The split keeps quotations comparable when coating or grade options differ. It also clarifies which requirement belongs to the surface system and which belongs to forming performance.
AFP means an anti-fingerprint surface requirement. Confirm the treatment, passivation, oiling, handling expectations and roll-forming compatibility. The finished appearance depends on the surface specification and downstream process, not on AZ150 alone. Ask for storage guidance before approval. The buyer should also state which face remains visible after forming, how long the coil may be stored before processing and whether the finished sheet will receive cleaning, painting or another treatment. Those details help the supplier review AFP as part of the actual roofing workflow, not as an isolated label.

This AZ150 G550 AFP Galvalume coil is intended for buyers who need a defined aluminium-zinc coating, high-strength grade and controlled surface treatment for roofing-sheet production. The final profile and forming route should be reviewed before order confirmation.
For material selection, compare this product with the Galvalume Steel Coil range. For prepainted roofing applications, review the Color Coated Galvalume Coil (PPGL) range.
Confirm whether the order requires parent coil, slit coil or another processed format. Share the roofing profile, bend geometry, tooling range, minimum bend requirement, coil weight and tolerance schedule before production review. G550 can require a different forming assessment from lower-strength grades, so the forming route should be checked against the drawing. Include the line direction and edge condition when the roll-forming setup requires them.
Confirm export packing, wrapping, strapping, edge protection, moisture protection, coil orientation, shipping marks and destination requirements per order. The buyer should also state the expected coil weight and loading limits so the packing plan matches the handling and shipment route.
No. AZ150 is the aluminium-zinc coating class. G550 is the steel grade. Keep both separate.
AFP means an anti-fingerprint surface requirement. Confirm the treatment, passivation, oiling and forming compatibility per order.
It can be reviewed when grade, dimensions, profile and forming route match the project. Send a drawing with fixed bend details.
State the required standard. ASTM A792 may be requested, but the final standard and inspection basis must be confirmed per order.
Send thickness, width, tolerance, coil ID, coil OD and quantity. Add slit-width or profile requirements when applicable.
No. High strength can affect bending, tooling and minimum bend requirements. Send the roofing profile before approval.
State passivation and oiling separately from AFP, then confirm storage and forming compatibility.
Specify wrapping, strapping, edge protection, moisture protection, marks and the destination.
