What Makes a Metal Asset Tag Durable?

Durability is the performance of the complete identification system rather than one individual material property.

Define the Operating Environment First

The same tag specification will not suit every office, workshop, production line, outdoor machine or chemical-processing area.

Ask about the worst realistic condition

Selection should consider cleaning chemicals, maximum temperature, vibration, exposure and handling—not only normal appearance in a clean room.

Metal Asset-Tag Material Comparison

Stainless-Steel Asset Tags

Suitable when:

• The tag may experience impact or repeated handling
• Greater rigidity is required
• A dark direct mark is preferred
• A recessed engraving is required
• The equipment has a premium or industrial finish
• The selected grade suits the service environment

Surface-finish options

• Brushed
• Matt
• Bead blasted
• Mirror polished
• Painted or coated

Important limitations

Stainless steel is not universally rust-proof. Grade, fabrication, contamination, cleaning chemicals, salt exposure and installation conditions affect corrosion performance.

Reflective glare

Mirror and polished surfaces can make small QR Codes or Data Matrix symbols harder to scan under certain lighting angles.

Anodised-Aluminium Asset Tags

Suitable when:

• Low weight is important
• Strong light-on-dark contrast is required
• Colour coding is useful
• Large quantities are needed
• The plate is mounted on lightweight equipment
• Fast surface marking is preferred

Common colours

Black, blue, red, gold, silver and other supplier-specific anodised colours may be available. Shade can vary between anodisers and production batches.

Surface marking vs deep engraving

A bright mark on dark anodised aluminium commonly results from altering or removing the coloured anodic surface. It may have little measurable depth.

Thickness matters

Very thin aluminium can bend, crease or lift at the corners. The final thickness should match the plate size, mounting method and handling conditions.

Painted and Powder-Coated Metal Tags

Painted and powder-coated metal can support customised colours and strong contrast when the laser removes or changes the coating.

Before production, confirm:

• Base metal
• Coating type
• Coating thickness
• Colour and gloss level
• Expected chemical exposure
• Whether exposed metal needs protection

Batch consistency

Products with the same colour description can use different coating formulations or thicknesses and may require different settings.

Tag Thickness and Rigidity

Thickness affects weight, rigidity, edge safety, drilling, adhesive contact and the ability to remain flat.

Thin tags

• Lower material and shipping weight
• Easier to bend around a gentle curve
• More likely to crease or lift
• May show heat distortion during aggressive engraving

Thicker tags

• Greater rigidity
• Better resistance to handling damage
• More suitable for screws or rivets
• Heavier and potentially more expensive

No universal best thickness

The suitable thickness depends on tag dimensions, metal, mounting method, curvature, exposure and whether the tag must remain removable.

Size, Corners, Holes and Edge Finishing

Overall size should accommodate:

• Asset number
• Company identifier
• QR Code or Data Matrix
• Quiet zone
• Mounting holes
• Safe margins
• Optional contact information

Rounded corners

Rounded corners can reduce sharp points and are often more suitable for frequently handled equipment.

Mounting holes

Hole diameter and spacing should be approved before production. Keep codes, text and quiet zones clear of holes, washers and screw heads.

Deburring

Cut metal edges may require deburring or additional finishing before handling and installation.

Choose the Correct Marking Process

Match the process to the lifecycle

A smooth dark mark may be suitable for compact codes, while a deeper recess may be preferred where the equipment experiences heavier abrasion or later refinishing.

What Information Should Be Included?

Common permanent information

• Company or organisation name
• Asset number
• Machine-readable code
• Equipment category
• Contact or reporting instruction

Information to include only when useful

• Department
• Location code
• Purchase year
• Model
• Internal cost centre

Avoid information that changes frequently

Employee names, room numbers, inspection dates and current maintenance status may become outdated. Store changing information in the asset database and use the tag to link to the record.

Create a Controlled Asset-Numbering System

The asset number should be unique, stable and easy to use throughout the organisation.

A numbering format may include:

• Organisation prefix
• Asset category
• Location or department code
• Sequential number
• Check digit where the system requires it

Avoid overloading the number

Encoding too many changing attributes into the asset number can create problems when equipment moves location or department.

Never reuse identifiers casually

Retired, lost or disposed assets should remain recorded so their numbers are not accidentally assigned to new equipment.

Internal Asset Numbers, GIAI and GRAI

Internal asset number

Suitable when the identification system is used only within the organisation and does not require external standards-based exchange.

Global Individual Asset Identifier

GIAI can be used to uniquely identify an individual asset such as a machine, computer, vehicle, piece of equipment or spare part.

Global Returnable Asset Identifier

GRAI can be used for reusable or returnable assets such as transport equipment, pallets, containers or tools and can identify the asset by type and, where required, individually.

QR Code or Data Matrix for Asset Tags?

Include human-readable text

The asset number should remain visible even when the code is dirty, damaged or cannot be scanned.

Read QR Code vs Data Matrix for Metal Marking and Industrial Traceability.

Human-Readable Identification

Human-readable information provides backup identification and helps staff confirm that the correct database record has opened.

Recommended elements

• Asset number
• Organisation name or logo
• Short instruction such as “Scan for Record”
• Optional reporting contact

Use clear typography

Choose a simple font, sufficient character height and adequate spacing. Avoid extremely narrow, decorative or condensed fonts.

Do not rely on colour alone

Asset categories should also be distinguishable through text, symbols or database data rather than only the tag’s background colour.

Layout and Readability

Establish a visual hierarchy

1. Organisation identity.
   Show who owns or manages the asset.
2. Asset number.
   Make the primary identifier easy to find and read.
3. Machine-readable code.
   Preserve code geometry, quiet zones and sufficient module size.
4. Secondary information.
   Keep instructions and contact details subordinate to the main identifier.

Allow safe margins

Keep text and codes clear of holes, edges, bends, washers, screw heads and rounded corners.

Test at actual size

A tag enlarged on a monitor can appear readable even when the final physical text or code is too small.

Asset-Tag Mounting Comparison

Adhesive-Mounted Asset Tags

Adhesive mounting may suit:

• Smooth painted cabinets
• Office equipment
• Clean indoor machinery panels
• Assets where drilling is prohibited

Adhesive selection should consider:

• Surface material
• Paint or powder coating
• Surface energy
• Texture and flatness
• Temperature range
• Moisture
• Cleaning chemicals
• Vibration
• Required removal method

Surface preparation

Follow the adhesive manufacturer’s instructions. The surface normally needs to be sound, clean and dry, and some finishes may require an approved primer or additional preparation.

Allow the adhesive system to develop

Pressure, contact area, application temperature and the time before the equipment returns to service can affect final bond performance.

Rivets and Screw Mounting

Advantages

• Mechanical retention
• Suitable for vibration when specified correctly
• Less dependence on paint adhesion
• Visible evidence of removal or tampering

Important checks

• Permission to drill
• Wall thickness
• Hidden cables or components
• Pressurised sections
• Required corrosion compatibility
• Fastener projection inside the equipment
• Vibration-loosening control

Mixed-metal contact

Fastener and tag materials should be reviewed where dissimilar metals, moisture or conductive contamination could contribute to galvanic corrosion.

Do not drill safety-critical equipment without approval

Tanks, electrical enclosures, guards, structural members and certified equipment may require manufacturer or engineering approval before modification.

Wire, Chain and Cable-Tie Mounting

Suspended tags can identify assets that have no suitable flat mounting surface.

Suitable examples

• Valves
• Tools
• Hoses
• Cables
• Portable equipment
• Temporary installations

Risks

• Rotation makes scanning difficult
• Movement can abrade the tag or equipment
• Loose tags can become entangled
• Cable ties can become brittle or loosen
• Sharp wire ends can create handling hazards

Keep clear of moving parts

Do not install a hanging tag where it can contact belts, shafts, fans, cutting tools, hot surfaces or operator controls.

Choose the Installation Position Carefully

The tag should be:

• Visible during normal inspection
• Accessible to the intended scanner
• Protected from direct impact where practical
• Away from oil or water collection points
• Clear of moving parts
• Clear of extreme heat
• Clear of frequently gripped surfaces

Do not cover:

• Manufacturer serial plates
• Regulatory or certification labels
• Safety warnings
• Emergency instructions
• Inspection stickers
• Control labels
• Ventilation openings
• Service-access points

Photograph the approved position

A reference photograph helps installers place all tags consistently and avoids ambiguity in large facilities.

Installation Safety on Equipment and Machinery

Tag installation can involve drilling, opening panels, working near moving parts or contacting electrical, pneumatic, hydraulic, thermal or mechanical energy sources.

Before installation:

• Obtain site and equipment-owner approval
• Review the machine manual
• Identify energy sources and stored energy
• Follow the organisation’s isolation and lockout/tagout procedure
• Use authorised and competent personnel
• Confirm there are no hidden cables, pipes or components
• Use suitable tools and personal protective equipment

Asset tags are not lockout tags

A permanent identification plate must not be used as a substitute for a lockout/tagout device, safety warning, inspection certificate or operating instruction.

Connect the Tag to a Managed Asset Database

Useful database fields

• Asset number
• Description
• Manufacturer
• Model
• Original serial number
• Department
• Current location
• Custodian
• Purchase date
• Warranty
• Maintenance history
• Status
• Retirement or disposal record

Use stable code destinations

A tag may remain in service longer than a software platform or web address. Use controlled redirects or stable record identifiers where appropriate.

Protect sensitive records

A visible QR Code can be photographed. Require authentication where the linked record contains private, financial, security or operational information.

Variable-Data and Batch Production

Each tag may contain a different asset number, QR Code, Data Matrix symbol, location or equipment reference.

Recommended spreadsheet columns

Data checks

• Preserve leading zeros
• Check duplicates
• Confirm code destinations
• Confirm tag dimensions
• Match mounting configuration
• Lock the approved spreadsheet
• Record rejected or cancelled numbers

Batch software

Current xTool Studio tools can support spreadsheet import, code generation and automatic sequences, but physical matching, scanning and quality checks remain necessary.

Test the Complete Asset-Tag System

Possible testing categories

Use representative equipment surfaces

An adhesive test on clean laboratory metal may not represent aged paint, textured powder coating or an oily factory surface.

Test after cleaning

Evaluate the tag after the actual cleaning process, not only immediately after installation.

Customer defines acceptance

Where formal abrasion, corrosion, chemical or DPM verification is required, the customer should provide the applicable test method and acceptance criteria.

Production Quality-Control Workflow

1. Verify the approved spreadsheet.
   Check uniqueness, leading zeros, code data and quantities.
2. Verify the tag specification.
   Confirm material, thickness, dimensions, holes and mounting method.
3. Produce the first article.
   Use the final marking process and actual-size artwork.
4. Inspect appearance.
   Check contrast, depth, edge finish and surface damage.
5. Scan the machine-readable code.
   Confirm the data and destination using the intended reader.
6. Approve mounting.
   Test adhesive or fastener compatibility on a representative surface.
7. Begin controlled batch production.
   Maintain the spreadsheet and jig sequence.
8. Perform intermediate checks.
   Inspect and scan samples throughout production.
9. Match each tag to the installation list.
   Confirm asset number, equipment and packaging label.
10. Record rejected identifiers.
    Do not reuse cancelled numbers without customer approval.

Inspection, Maintenance and Replacement

Inspect tags periodically for:

• Loose edges
• Corroded fasteners
• Cracks or deformation
• Unreadable text
• Code-scanning problems
• Paint or chemical damage
• Incorrect database records

Replace the tag before identification is lost

Create a controlled replacement procedure that retains the original asset number and records why the previous tag was replaced.

Update the database when equipment moves

Location and custodian information should normally be changed in the database rather than by producing a new permanent asset number.

Common Metal Asset-Tag Failures

Application Recommendations

What Affects the Price?

Quotation factors include:

• Metal type and grade
• Thickness
• Tag dimensions
• Corner shape
• Holes, slots and edge finishing
• Marking process
• Engraving area
• QR Code or Data Matrix generation
• Variable asset numbers
• Spreadsheet preparation
• Adhesive backing or fasteners
• Sample testing
• Scanning or formal verification
• Sorting, installation grouping and packaging

Variable tags require more control

Every tag must be generated, marked, scanned, matched and packaged according to the equipment list.

Installation may be a separate scope

Site access, equipment isolation, surface preparation, drilling, travel and installation records should be quoted separately when applicable.

Information Needed for an Accurate Quotation
