Overview
This inspection template is used to verify that galvanized sheet or fabricated parts meet the coating designation required by the order, such as G90, G115, or G140. It captures the material heat or lot number, the inspection stage, the source of the coating claim, and the mill data or test report used to confirm the result. It also records the visible condition of the galvanized surface so the inspector can note damage, exposed edges, cutouts, or formed areas that may reduce corrosion protection.
Use this template when coating weight is part of the acceptance criteria for incoming material, in-process verification, or final release. It is especially useful for bins, panels, cabinets, brackets, guards, and other fabricated parts where the wrong coating designation can lead to early rusting, customer rejection, or warranty issues. The record is also helpful when a supplier provides certified data and you need objective evidence that the lot matches the purchase order or drawing.
Do not use this template as a substitute for a full dimensional inspection, weld inspection, or process qualification audit. It is not the right tool when the coating requirement is absent, when the material is painted or otherwise coated instead of galvanized, or when the question is about corrosion system design rather than coating verification. If the part has been cut, formed, or damaged after galvanizing, the template should be used with a careful review of exposed areas and any need for repair or disposition before release.
Standards & compliance context
- This template supports ISO 9001:2015-style control of incoming material verification, traceability, and objective evidence of conformity.
- It helps document conformance to customer and industry specifications for galvanized coating classes such as G90, G115, and G140.
- For fabricated products used in safety-related or code-sensitive applications, the record can support quality control expectations under applicable general industry or construction standards.
- If the part is intended for a regulated end use, retain the inspection record with the lot history so the coating designation can be traced during audits or complaints.
- When customer requirements reference a consensus standard or coating specification, use that document as the acceptance basis rather than relying on appearance alone.
General regulatory context for orientation only — verify current requirements with counsel or the relevant agency before relying on this template for compliance.

Document any visible stains, white rust, dark spots, or other surface conditions noted during inspection.
-
Edges, cutouts, and formed areas protected
Verify edges, cutouts, bends, and formed areas do not show unacceptable bare metal or coating loss.
-
Additional corrosion protection concerns
Record any condition that may affect service life or corrosion resistance.
Non-Conformance and Release
This section records the decision path when the material fails, including disposition, corrective action, and final authorization to release.
-
Non-conformance identified
Indicate whether any coating designation mismatch, low coating weight, or surface defect was found.
-
Disposition selected
Choose the disposition for the inspected material if a deficiency was found.
-
Corrective action documented
Describe the corrective action, containment, or supplier notification required for any non-conformance.
-
Quality release authorized
Confirm the material is released for use or shipment after verification and review.
How to use this template
- 1. Enter the order, drawing, or specification requirement and record the material heat or lot number so the coating claim can be traced to the correct shipment or part.
- 2. Confirm the required coating designation from the purchase order, customer specification, or reference standard and attach the mill data or test report that supports the claim.
- 3. Record the measured or certified coating weight, identify the sampling method used, and verify that the result matches the required G90, G115, or G140 designation within the stated acceptance criteria.
- 4. Inspect the surface for continuity, visible damage, exposed edges, cutouts, and formed areas, and document any condition that could reduce corrosion protection.
- 5. If any requirement is not met, open a non-conformance, select the disposition, document corrective action, and obtain quality release only after the issue is resolved.
Best practices
- Verify the coating designation against the order before you review the mill data, so a mismatched document does not get accepted by mistake.
- Record the heat or lot number exactly as shown on the material tag, bundle label, or test report to preserve traceability.
- Use the actual measured or certified coating weight as the acceptance basis when available, not a visual estimate of how bright or dull the zinc surface looks.
- Photograph the marked material, test report, or other evidence at the time of inspection so the release record stands on its own later.
- Pay close attention to cut edges, punched holes, bends, and formed areas because these are common places where corrosion protection is reduced after fabrication.
- Treat missing mill data, unreadable labels, or unsupported coating claims as a non-conformance until the evidence is verified.
- Separate cosmetic surface notes from true corrosion-protection deficiencies so the disposition reflects the actual risk to the part.

Common use cases
Frequently asked questions
What does this galvanized coating verification template check?
It checks whether the galvanized sheet or fabricated part matches the coating designation required by the order, drawing, or customer specification. The template captures traceability, the source of the coating claim, measured or certified coating weight, and the visible condition of the surface. It is designed to confirm that the material received or produced actually provides the corrosion protection expected for the application.
When should this inspection be used?
Use it at incoming receiving, after galvanizing, before fabrication release, or before shipment when coating designation matters to the end use. It is especially useful for bins, panels, enclosures, brackets, and other parts where corrosion resistance depends on the specified zinc coating. Do not use it as a substitute for a full process audit of the galvanizing line or for unrelated dimensional inspections.
Who should complete this audit or inspection?
A quality inspector, receiving inspector, or trained production verifier can complete it, provided they understand the required coating designation and how to read mill data or test reports. If the result depends on a lab test or certified documentation, quality or engineering should review the evidence before release. The person signing should be able to explain any non-conformance and the disposition chosen.
How often should coating weight be verified?
Verify it for each incoming lot, each finished lot, or at the frequency defined by the customer specification and your quality plan. Higher-risk jobs, first articles, and supplier changes usually justify more frequent checks. If the material is already certified and traceability is strong, you may use a reduced sampling plan, but the template still records the basis for acceptance.
Does this template align with any standards?
Yes, it supports quality verification practices used under ISO 9001:2015 and can be tied to customer specifications for galvanized coating classes such as G90, G115, and G140. It also helps document conformance to general industry expectations for material control and traceability. If the material is used in a regulated environment, the inspection record can be retained as objective evidence of acceptance.
What are the most common mistakes this template helps prevent?
Common mistakes include accepting the wrong coating designation, relying on a label without mill data, and overlooking damage at cut edges or formed areas. Another frequent issue is treating a visible galvanized finish as proof of the correct coating weight when the actual designation was never verified. The template forces the inspector to record the source of the claim and the evidence behind it.
Can this be customized for different suppliers or products?
Yes, you can add supplier-specific document fields, customer acceptance criteria, or product-specific notes for bins, panels, racks, or fabricated assemblies. You can also adjust the sampling method, tolerance language, and release authority to match your internal quality procedure. The core structure should stay the same so every lot is judged against the same coating requirement.
How does this compare with a quick visual check?
A visual check only tells you that the surface looks galvanized; it does not confirm the coating designation or whether the coating weight meets the order. This template combines traceability, documentation review, measured or certified results, and surface-condition checks in one record. That makes it much better for release decisions, supplier disputes, and customer audits.
