Aluminium-zinc coating specification

ParameterReference
Coating alloy55% Al / 43.5% Zn / 1.5% Si nominal
EN designationAZ + total coating mass in g/m²
AZ150150 g/m² minimum total, both sides, three-spot basis
ASTM designationsAZ50 / AZ55 use oz/ft²; specify ASTM A792/A792M
Coating vs strengthSelect the base grade independently
Surface treatmentAnti-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

PropertyOptions
Surface finishRegular spangle, minimized spangle or skin-passed
PassivationChromate or chromium-free treatment
Additional protectionAnti-fingerprint, passivation plus oil, oiled or untreated
Coating designationState AZ designation, total coating mass and applicable EN or ASTM standard

Surface treatment codes vary by supplier. Specify the required finish rather than assuming a code is universal.

Frequently asked questions

What should a galvalume coil roll-forming RFQ include?

Provide the substrate grade and purchasing standard, metallic coating designation, thickness basis and input width. Add the profile or drawing, forming requirements, surface treatment and quantity. State the maximum coil weight and required inner diameter to match your production line.

How do I compare AZ coating designations on galvalume coil?

Ask each supplier to identify the governing standard, designation and measurement units. Compare the coating requirements on the same basis, including whether the quoted value applies to both surfaces combined. Do not compare designation numbers alone when standards or units differ.

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.
