Visual Inspection & Acceptance Standards
These are the Seller’s applicable visual inspection and acceptance standards referred to in Clause 1.7 and Clause 7 of the Terms & Conditions of Sale. Finishes and coatings are assessed against the standards in force at the date of manufacture.
Powder Coating Visual Inspection Standards
Section 1 of 3Visual inspection of powder coating involves assessing the significant surface under diffuse daylight or standard lighting at defined distances based on the application type. The primary objective is to verify that the finish is uniform and free of defects that compromise performance or aesthetics.
Standard Inspection Conditions
| Parameter | Standard Requirement |
|---|---|
| Lighting | Diffuse daylight or a standard 40W equivalent fluorescent light source without direct glare. |
| Viewing Angle | Perpendicular (90 degrees) to the test surface. |
| Interior Distance | 1.5 meters away from the target object. |
| Exterior Distance | 3 meters away from the target object (architectural parts). |
Acceptance Criteria Classes
- Class A (Aesthetic / High Visibility): Zero prominent flaws, uniform color/gloss, smooth texture, and highly controlled orange peel. Typically specified for consumer-facing or premium architectural components.
- Class B (Semi-Critical / Moderate Visibility): Minor textural variations or slight cosmetic inconsistencies allowed in less noticeable areas.
- Class C (Functional / Hidden): Prioritizes corrosion protection over appearance. Minor runs, pinholes, or color mismatches are acceptable for hidden functional components.
Common Surface Defects to Reject
- Blisters & Craters: Raised spots or fisheyes caused by oil, moisture, or surface contamination.
- Orange Peel: Excessive rough or bumpy texture surpassing approved Powder Coating Institute (PCI) visual standards.
- Inclusions: Trapped dirt, dust, lint, or burnt particles embedded in the cured film.
- Discontinuities: Pinholes, thin spots, sagging, or bare metal exposure that voids corrosion barriers.
Powder Coating over Galvanized Substrates
This document establishes the uniform testing environment, distance parameters, and surface acceptance criteria for the visual evaluation of architectural and industrial powder-coated hot-dip galvanized parts.
1. Inspection Environment & Methods
All visual evaluations must be executed under the following standardized conditions:
- Viewing Distance (Exterior/Façade): 3 meters minimum from the significant surface.
- Viewing Distance (Interior/General): 1.5 meters minimum from the significant surface.
- Illumination Level: Diffuse natural daylight or artificial light providing 500 to 1000 lux. Avoid direct sun or blinding glare.
- Observation Angle: Perpendicular (90 degrees relative to the test plane).
- Evaluation Window: Defects must be readily visible without magnification from the stipulated viewing distance to be considered rejectable.
2. Surface Defect Classification Matrix
| Defect Type | Classification | Description & Field Actions |
|---|---|---|
| Blisters / Outgassing Bubbles | Rejectable | Caused by gas escaping the porous galvanized layer during thermal curing. Disrupts coating continuity. |
| Pinholes & Holidays | Rejectable | Microscopic voids breaking completely through to the zinc layer, posing high corrosion risk. Requires strip and re-coat. |
| Craters & Fish Eyes | Rejectable | Depressions induced by local surface contaminants like oils, silicones, or shop dust prior to powder application. |
| Zinc Spikes & Ash Protrusions | Rejectable | Rough dross or spikes from the hot-dip galvanizing phase breaching the powder envelope. Must be mechanically ground flat before coating. |
| Runs, Sags, & Drips | Acceptable* | Zinc coating build-up or gravity sag during melting. Unacceptable on significant surfaces. |
| Orange Peel Texture | Acceptable* | Mild wave texture is inherent. Acceptable if it matches the pre-approved baseline reference limit panels. |
| Substrate Print-Through | Acceptable* | Faint visibility of underlying zinc spangle patterns is permissible provided specified dry film thickness (DFT) is verified. |
Wet Paint Parts Visual Inspection Standards
Section 2 of 3Visual inspection standards for wet-painted parts require controlled lighting (1,000–4,000 lux), a 45-degree viewing angle, and a fixed distance of 24 to 48 inches depending on the part class. Inspectors check for complete coverage, smooth consistency, and the total absence of critical defects within designated time limits.
1. Environmental and Setup Controls
- Lighting: Use natural daylight simulation or calibrated overhead lamps producing 1,000 to 4,000 lux.
- Distance & Time: Inspect Class A (critical) parts at 24 inches for 10 seconds; inspect Class C parts at 48 inches for 3 seconds.
- Angle: Position the part or eye at a 45-degree angle to catch surface reflections and gloss variances.
2. Quality Classification Matrix
| Defect Category | Class A (Critical / High Visibility) | Class C (Low Visibility / Hidden) |
|---|---|---|
| Runs, Sags, & Drips | Zero tolerance for visible micro-tears or heavy sagging. | Acceptable if within functional tolerance limits. |
| Blisters & Pinholes | Zero tolerance. Complete structural rejection. | Limited microscopic occurrences allowed if sealed. |
| Dirt, Dust, & Inclusions | Zero foreign particle inclusions on visible faces. | Limited small specks allowed on non-visible areas. |
3. General Acceptance Criteria
- Orange Peel & Texture: Evaluated against approved visual boundary master panels or physical roughness scales.
- Coverage & Hiding: Complete, uniform coating of the substrate with no shadow-through, thin spots, or missed edges.
Wet Paint Coating on Galvanized Substrates
Scope: This document outlines the mandatory quality control checkpoints and acceptance criteria for the visual inspection of liquid coatings applied to hot-dip galvanized steel components.
1. Pre-Paint Galvanized Surface Check
Before any liquid coating is applied, the galvanized profile must be strictly verified to ensure complete coating adhesion and avoid premature failure modes like peeling or osmotic blistering.
- Zinc Condition Assessment: Inspect for and mechanically remove any sharp zinc spikes, heavy dross lumps, rough zinc drips, or flux residues by careful grinding, filing, or scraping.
- Surface Contamination: Verify the absolute absence of hydrocarbon oils, processing grease, workshop dirt, and zinc oxidation products (white rust / wet storage stains). Surface must be chemically clean.
- Surface Profile Verification: Ensure mandatory mechanical profile creation via sweep blasting (using non-metallic mineral abrasives) or chemical pretreatments (e.g., T-wash mordant solution). This process must provide a uniform matte profile without breaching or excessively stripping the underlying protective zinc layer.
2. Wet Paint Visual Defects & Acceptance Criteria
The liquid-applied film layer must display flawless structural continuity. The following inspection matrix defines the defect criteria during wet and early-curing phases:
| Inspection Parameter | Visual Defect Description | Acceptance Status |
|---|---|---|
| Coverage & Continuity | Thin spots, pinholes, missed areas, or underlying zinc substrate showing through the coating. | Reject Must achieve 100% complete visual hiding power. |
| Surface Imperfections | Cratering, active bubbling, severe solvent blistering, wrinkling, or fish-eyes due to contamination. | Reject Any break in film integrity requires repair. |
| Application Flaws | Excessive paint sagging, heavy fluid runs, deep drips, or pronounced orange-peel textures. | Reject if exceeding specified dry film thickness or causing aesthetic defects. |
| Adhesion Screening | Early structural blistering, micro-cracking, or checking over the galvanized substrate profile. | Reject Mandates immediate cross-hatch testing (ASTM D3359). |
Galvanising Specification – EN ISO 1461
Section 3 of 3 · Surface features that meet and do not meet the specificationThe following reference photographs illustrate surface features that commonly occur on hot-dip galvanized steel. Each is classified as meeting or not meeting EN ISO 1461, with the typical cause (Feature) and the recommended remedy or preventative measure (Action).
Meets EN ISO 1461
15 features
Zinc AshDesign/Process Issue
- Ash deposit and entrained ash
- 1. Poor design has created air lock where ash has trapped
- 2. Ash reformed after skimming the bath surface and become entrained within the coating
- Avoid trapped ash by provision of a vent hole
- Movement of work in the galvanizing bath may prevent ash becoming trapped
- Avoid entrained ash by improved skimming practice at the galvanizing bath (may not be 100% effective)
Weld Seepage StainingEnvironmental Issue
- Weld seepage stain
- Pretreatment chemicals become trapped in weld pin holes and are dried out by the heat of the galvanizing process leaving a residue
- Moisture drawn into the pin hole after galvanizing resulting in residue dissolving and seeping out staining the steelwork
- No process related action can prevent weld seepage
SnailingMaterial/Process Issue
- Snailing - textured finish with rivulets of zinc running around the CHS
- Variation in steel chemistry across the surface results in variable coating growth
- May be exacerbated if work is withdrawn quickly and/or at a shallow angle
- Ensure work is withdrawn slowly at a steep angle to aid the drainage of zinc
- Even following best practice snailing can still occur
Zinc Build-upDesign Issue
- Area of zinc build-up due to drainage of zinc during withdrawal from the galvanizing bath
- Poor design has created a zinc trap
- Advise customer of need for drainage holes or to crop the corners of stiffeners to aid the drainage of zinc and avoid zinc traps
Swarve StainingEnvironmental Issue
- Steel has been cut nearby the galvanized product and swarve has embedded into the galvanized coating
- Swarve may rust giving the appearance of the galvanized coating having failed
- Can remove staining by wire brushing
Entrained DrossProcess Issue
- Entrained dross in the coating due to floating dross
- Floating dross caused by disturbance of the bottom dross layer or due to bath composition resulting in low density dross
- Ensure work is not lowered too far into the bath so disturbing the dross layer
- Control bath composition especially %Al to prevent low density floating dross
- Stop processing work and allow dross to settle to the bottom of the bath
Wet Storage StainEnvironmental Issue
- Formed due to galvanized product becoming damp and being unable to fully dry out
- Store indoors
- Orientate work so water traps are not formed
- Ensure work is stacked at an angle to aid water run-off
- Ensure work is not stacked tightly together
- Do NOT shrink wrap work
Double Dip MarkProcess Issue
- Double dip mark formed due to double dipping because work will not fit into the galvanizing bath in a single immersion
- Temperature differentials formed with one end cooling while the other is heating-up affect the coating’s appearance
- Ensure best practice is followed when double dipping with work being turned in between dips so as to minimise the area of overlap
Flame Cut EdgeFabrication Issue
- Edge of steel has been flame cut
- Flame cutting may deoxidise the steel surface giving a lower or variable silicon content and reactivity
- Can result in a textured finish and/or a coating thickness which is below standard requirement
- Fabricator should grind the flame cut edge prior to sending work for galvanizing
- No process related solution
Mechanical DamageMaterial/Process Issue
- Damage due to heavy impact especially at corners and edges
- More likely if a thick coating has been formed
- Minimise handling
- Try to avoid metal to metal contact
- Handle with a level of care and do not abuse the product
- Use plastic straps rather than chains where possible
Colour VariationMaterial Issue
- Variation in coating appearance
- Steel with a higher silicon content may result in continued growth of the zinc-iron alloy layer following withdrawal from the galvanizing bath
- Retained heat may act as a driving force even at lower silicon levels
- If the zinc-iron alloy layer is visible at the coating surface it appears duller, darker grey in appearance
- Use of nickel in the galvanizing bath may help reduce reactivity effect
- Quenching work immediately after galvanizing can remove retained heat
Tree BarkMaterial Issue
- Localised variation in steel chemistry affects surface reactivity
- Localised areas with high %Si are more reactive and form a thicker coating resulting in a textured orange peel or tree bark coating
- Advise customer to minimise potential by using steel with a controlled silicon content (< 0.04% or 0.15-0.25% Si)
Timber StainingEnvironmental Issue
- Staining occurs from damp timber
- Use of timber to avoid metal to metal contact is good practice
- Staining may be removed by wire brushing
Steel DefectSteel Issue
- Steel defects rolled into the steel surface and not visible to the naked eye
- The heat of the galvanizing process causes defects to expand and become more apparent
- Zinc may get beneath the defect forming a coating so the defect is raised up proud of the steel surface
- Due to poor steel quality
- Grind out the steel defect and repair
- No process related solution
Uneven DrainageProcess Issue
- Uneven drainage results in an uneven or lumpy area on which zinc build up has occurred
- This can occur over the entire surface or in isolated areas. Uneven drainage also includes drips on the ends of parts, runs near holes. A cause may be high withdrawal speed and/or the galvanizing temperature being too low
- This condition does not adversely affect coating performance and is acceptable
Does not meet EN ISO 1461
10 features
Wire MarksProcess Issue
- Wire mark
- Wires used for jigging contact with work during dipping preventing a coating from forming
- Wires are left on work after the product has cooled and tear the coating when removed
- Movement of work in the galvanizing bath should assist in a continuous coating being formed
- Remove wires as soon as is practically possible after galvanizing
- Repair wire marks if sufficiently small
Oil ContaminationMaterial Issue
- Surface contaminant present on steel surface which could not be removed by the normal pretreatment process e.g. oil/grease
- Ask fabricator to avoid contamination of work for galvanizing with oil/grease
- Use of a degrease tank might remove light oil or grease
Paint MarkingMaterial/Process Issue
- Work delivered to the galvanizing in an unsuitable condition for processing
- Paint ID not removed prior to galvanizing
- Advise fabricator to use a water based or water soluble marker for ID of work which may come off in the normal pretreatment process
- Remove paint by use of paint stripper or grinding prior to processing work
Sharp StriationMaterial Issue
- Stress in the steel surface has affected reactivity
- Areas of increased reactivity following the stress pattern result in increased coating growth as sharp striations around the diameter of the bar
- Advise fabricator that steel is not suitable for galvanizing
- Can lightly grind to remove striations
- No process related solution
Flux StainingProcess Issue
- Flux staining may result in rapid local attack on the coating if it becomes damp
- Quenching work may help to remove flux staining
- Flux staining should be removed manually before delivery of work
Chain MarksProcess Issue
- Small uncoated areas
- Where a chain is used to jig heavy work chain links have remained in contact with work during processing
- Movement of work in the galvanizing bath may assist formation of a coating
- Repair chain marks if sufficiently small
Label MarkMaterial/Process Issue
- Uncoated area due to use of an adhesive label on black steelwork
- Label not removed before galvanizing or adhesive from label not removed from steelwork by the normal pretreatment process
- Results in an uncoated area
- Ask fabricator not to use adhesive labels
- If adhesive labels are present remove them and clean the area manually to try and remove the adhesive
- Repair area if sufficiently small (unlikely)
Weld Anti-Spatter SprayFabrication Issue
- Uncoated area adjacent to weld(s)
- Oil based or silicone based weld anti-spatter spray used during fabrication and burnt onto the steel surface
- Not visible to naked eye and prevents a galvanized coating forming
- Advise fabricator to use a water based or water soluble weld anti-spatter spray which will normally come off in the pretreatment process
- Repair area if sufficiently small
Zinc SpikeProcess Issue
- Sharp spike formed due to drainage of zinc following withdrawal from the galvanizing bath
- Ensure work is jigged to aid run-off of zinc
- Fettle work to remove spikes prior to delivery
Air LockDesign Issue
- Small uncoated area
- Poor design resulting in an air-lock so zinc does not contact with the steel
- Forms an uncoated area
- Advise fabricator to adequately vent work so as to avoid air-locks
- Repair area provided sufficiently small
