Plan your order
Material & processing
Specify dimensions and tolerances. Include the grade or describe your intended use if it is not yet selected.
Quantity & timing
Share your required tonnage and delivery date. Ask for stock availability, minimum order quantity and the dispatch schedule for your exact specification.
Packing & documents
Include destination, handling limits and required inspection documents so they can be reviewed with the material quotation.
Product details
Galvalume steel sheet enquiries need a defined length as well as thickness and width. For cladding panels or fabricated components, specify the coating, surface treatment and dimensional acceptance requirements. Identify whether you require flat cut-to-length sheets or a formed profile, since these describe different finished products.

Aluminium-zinc coating specification
| Parameter | Reference |
|---|---|

| EN designation | AZ + total coating mass in g/m² |
| AZ150 | 150 g/m² minimum total, both sides, three-spot basis |

| Coating vs strength | Select the base grade independently |
| Surface treatment | Anti-fingerprint / passivation / oiling as agreed |
Do not confuse AZ50 or AZ55 under ASTM with an EN coating mass in g/m².
Aluminium-zinc surface specification
| Property | Options |
|---|---|
| Surface finish | Regular spangle, minimized spangle or skin-passed |
| Passivation | Chromate or chromium-free treatment |
| Additional protection | Anti-fingerprint, passivation plus oil, oiled or untreated |

Frequently asked questions
What should I specify for cut-to-length galvalume sheets?
List the substrate grade and standard, aluminium-zinc coating designation, thickness, width, finished length and quantity. Include flatness, squareness and edge requirements. Add bundle weights, protective packing and the destination to define the supply scope.
Is flat galvalume sheet the same product as profiled roofing sheet?
Flat sheets and profiled roofing sheets have different finished dimensions and ordering requirements. A profiled sheet order also needs the profile drawing, effective cover width and formed length. Identify which product you need before comparing quotations.
How are minimum order and lead time confirmed?
Send your grade, size, tonnage and required delivery date. Ask for separate confirmation of stock availability, any production or processing time, and the dispatch date. Transit time depends on destination and shipment terms; the agreed quotation should state the minimum quantity and schedule.
What documents should I request?
List the required material test report, inspection document type and any third-party inspection in your enquiry. Ask which documents apply to your selected material and agree their scope before ordering. A general company certificate does not replace the material test results for the supplied heat or coil.
