Galvanized Coating Weight Verification (G90/G115/G140)

Inspection template to verify galvanized zinc coating designation on incoming or finished sheet against the order using mill data and/or test results, confirming corrosion protection for bins, panels, and related fabricated parts.

Inspection Details and Traceability

• Order, drawing, or specification identifies required galvanized coating designation
  Verify the required coating designation is clearly stated on the purchase order, drawing, traveler, or customer specification.
• Material heat/lot number recorded
  Record the heat number, lot number, coil number, or other traceability identifier for the inspected material.
• Inspection stage
  Select whether this verification is for incoming material, in-process material, or finished goods.
• Inspected part or product description
  Identify the part, panel, bin, coil, or assembly being verified.
• Inspection date and time
  Record when the verification was performed.
• Inspector name and signature
  Inspector completes and signs the verification record.

Specification Match

• Required coating designation
  Select the specified galvanized coating designation for the order.
• Verified coating designation matches order requirement
  Confirm the verified designation from mill data or test results matches the required designation.
• Coating designation source
  Identify the source used to verify coating weight designation.
• Reference standard or customer specification noted
  Document the standard, specification, or customer requirement used for acceptance.
• Mill data or test report attached
  Attach the supporting document used to verify coating designation.

Coating Weight Verification Results

• Measured or certified coating weight
  Enter the verified coating weight value from the mill certificate or test result.
• Coating designation confirmed by result
  Select the designation supported by the verified coating weight result.
• Sampling method documented
  Document the sampling method used for verification, including number of samples and location if applicable.
• Result within specified tolerance
  Confirm the verified result meets the required coating designation and acceptance criteria.
• Photo of marked material or test evidence
  Capture a photo of the material identification, test coupon, or report evidence when available.

Material Condition and Corrosion Protection

• Galvanized surface appears continuous and uniform
  Inspect for visible discontinuities, bare spots, excessive rust, peeling, or other coating defects.
• No visible damage that compromises corrosion protection
  Check for scratches, abrasion, edge damage, or handling defects that expose base metal or reduce corrosion protection.
• Surface condition observations
  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

• 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.
