Stainless Steel Decorative Coating
PVD Colored Stainless Steel Finish
Specifications, Supply & Technical Guide
PVD colored stainless steel finish combines a stainless substrate with a decorative physical vapor deposition coating applied in a vacuum process. The coating changes the visible color while the underlying base finish—such as mirror, brushed, satin, patterned or another approved texture—continues to influence gloss, reflection and surface character. For procurement, specify the base finish, color target, coating route, sample standard, visible side and final fabrication sequence.
Illustrative PVD Colored Surface

Illustrative visual reference only. Actual PVD color can vary with the coating system, stainless substrate, base finish, process batch, viewing angle, lighting and supplier route. Use an approved physical sample and agreed color / finish limit sample for appearance-critical production.
Finish Definition
What is a PVD colored stainless steel finish?
PVD colored stainless steel is stainless material that receives a decorative coating through a physical vapor deposition process carried out under vacuum.
The coating produces a metallic color effect without replacing the visual character of the base surface. A mirror substrate remains highly reflective, a brushed substrate retains directional grain, and a patterned substrate keeps its texture under the colored coating.
The term “PVD colored” therefore does not define one single color, one universal roughness value or one standard visual appearance. The buyer should define the target color, base finish, sample standard, acceptable color variation, coating side and fabrication / protection requirements.
Define these points before approving a PVD colored finish
- Stainless steel grade and product form
- Base surface finish before PVD coating
- PVD color target and approved physical sample
- Coating route / system and coated side
- Ra / Rz where substrate roughness is critical
- Color / reflectivity / gloss tolerance where applicable
- Protective film, defect acceptance and cleaning guidance
Finish Evidence
Technical and application evidence for PVD color approval
The page keeps the total image count to three. For PVD colored stainless, evidence should prove both the actual color and the base-surface character under controlled viewing conditions.
Technical evidence image
Use one combined image showing the real PVD-coated surface under controlled light, the approved color / finish sample and, where required, substrate Ra / Rz or color / gloss inspection evidence.
Application image
Use one real elevator panel, wall panel, trim, fixture or fabricated component showing the PVD color in its final installed or supplied condition.
Supply Specification
PVD colored stainless sheet, panel, coil and fabricated-part ordering matrix
Define the stainless grade, base finish, dimensions, color sample, coated side and fabrication sequence together. This table is an RFQ checklist, not live inventory.
Specify grade, thickness, dimensions, base finish, color and coated side.
Add panel layout, color matching, orientation and visible-area requirements.
Provide drawings, coated zones, post-forming requirements and final handling limits.
| Supply Form | Required Order Data | PVD Surface Control | Processing / Delivery Notes |
|---|---|---|---|
| PVD Sheet | Grade, thickness, width, length, quantity, base finish and coated side | Color sample, reflectivity / gloss, Ra/Rz if required and defect limits | Confirm protective film, interleave and packaging |
| Architectural Panel | Grade, panel dimensions, layout, quantity and orientation | Control color, tone, base-finish character and panel-to-panel consistency | Use approved limit samples for large visible installation areas |
| Cut / Formed Blank | Grade, thickness, blank dimensions, drawing and final visible face | Define whether forming / cutting occurs before or after PVD coating | Protect coated surfaces from tooling marks and edge damage |
| Fabricated Part | Drawing, grade, dimensions, quantity and coated zones | Define weld / bend areas, color match and final visual acceptance | Confirm fabrication sequence before coating approval |
Color availability, dimensions, coating route, base-finish combinations and fabrication capability must be confirmed in the actual quotation.
Finish Selection
PVD colored vs painted vs electroplated vs uncoated stainless steel
PVD colored stainless is a vacuum-deposited decorative coating system. It should not be confused with paint, powder coating, electroplating or an uncoated mill / mechanical stainless finish.
| Surface Route | Visual Character | Process Character | Selection Logic | Specification Note |
|---|---|---|---|---|

PVD Colored
This Page |
Metallic color while retaining base-finish character | Vacuum physical vapor deposition | When colored metallic stainless appearance is required | Specify color + base finish + approved sample |
| Paint / Powder Coat | Opaque colored coating | Liquid or powder coating system | When an opaque coating system is acceptable | Base stainless texture may be less visually dominant |
| Electroplated / Electrochemical Coating | Process-dependent metallic surface | Electrochemical deposition / treatment | When a specific electrochemical system is required | Do not substitute automatically for PVD |
| Uncoated Brushed / Mirror | Natural stainless color | Mechanical / mill finish only | When color coating is not required | No PVD color layer present |
Processing Route
Typical production route for PVD colored stainless steel
A repeatable PVD color requires control of the substrate, base finish, cleaning, vacuum coating process, color inspection and downstream handling.
Confirm Base Finish
Define grade, dimensions, visible side and substrate surface.
Clean & Prepare Surface
Remove contamination and prepare the approved substrate for vacuum coating.
PVD Vacuum Coating
Deposit the approved decorative coating under controlled process conditions.
Color / Surface Inspection
Compare color, gloss, tone and base-finish appearance to the sample.
Fabrication / Final Processing
Use the agreed sequence to minimize coating damage during cutting, bending or assembly.
Protect & Pack
Protect the colored surface from scratches, adhesive marks and handling damage.
Surface Control
Roughness, coating route, color tolerance and cleaning guidance
Do not publish invented Ra/Rz, coating-thickness or color tolerance values. Use actual production data, approved physical samples and agreed inspection methods for project-specific acceptance.
Ra / Rz & Production Route
The PVD layer is applied over an existing stainless surface, so the underlying base finish remains the main driver of visible texture and roughness character.
- Ra target: specify for the substrate / finished surface if required
- Rz target: specify where required
- Base finish: record exactly for repeatability
- PVD coating route: confirm supplier-specific approved system
Color, Reflectivity & Defect Acceptance
Color should be approved on the actual base finish because mirror, brushed and patterned substrates can change the perceived tone and reflectivity.
- Use an approved physical color / finish sample
- Define color / tone tolerance where measurable control is required
- Define gloss / reflectivity where critical
- Set scratch, pinhole, stain, color-shift and coating-uniformity criteria
Grades, Film & Cleaning
Confirm compatible grades and base finishes through the quotation. Protect the coated face and use cleaning methods that do not scratch or abrade the decorative coating.
- Grade / form: confirm by quotation
- Protective film: confirm adhesive / coating compatibility
- Use soft, non-abrasive cleaning materials
- Avoid uncontrolled polishing or abrasive rework on the coated face
Application Guidance

Custom Fabricated Parts
Drawing-controlled parts with specified PVD color, coated zones and visual limits.
Standards & Equivalence
How to specify PVD colored stainless steel without ambiguity
PVD colored stainless is generally a project-defined coated finish rather than one universal ASTM numbered finish. Specify the base stainless material and the decorative PVD coating requirements separately.
- Base stainless material standard Specify grade, dimensions, tolerances and the incoming base finish before coating.
- PVD coating specification Define color target, approved sample, coated side, process route and any project-specific coating performance requirements.
- Ra / Rz / color requirement Add measurable roughness, color, gloss or reflectivity criteria only where required.
- Visual approval Use controlled-light inspection and an approved sample / limit sample to control color, tone, surface character and visible defects.
Do not specify only a color name such as “gold” or “bronze”.
A color name does not define the exact coating system, base finish, reflectivity or acceptable batch variation.
The same PVD color family can look significantly different on mirror, brushed, satin or patterned stainless surfaces.
For visible work, approve a physical production sample, base finish, viewing condition and color / defect criteria before full production.
