Weld-On Metal Identification Tags & Serial Plates
Weld-On Metal Identification Tags and Serial Plates
Custom steel and stainless identification tags designed for attachment to fabricated equipment and assemblies.
Weld-on tags create a physical identifier on frames, skids, structures, attachments and heavy equipment where adhesive labels or hanging tags are unsuitable. They may be engraved, cut through or produced with customer-specified numbers and layouts.
Common weld-tag applications
- Fabricated equipment and structural assemblies
- Attachments, frames, skids and heavy components
- Serial numbers and production identifiers
- Customer or project codes
- Part, drawing and batch references
- Paint-over cut-through identification
Engraved or cut-through?
Engraved tags support smaller text and more detailed information. Cut-through characters remain physically open through the plate and may be useful when a weld tag will be painted with the equipment. Heavy coating can bridge small openings, so paint process and character size should be reviewed.
Information needed for an RFQ
- Base-metal preference and thickness
- Tag dimensions and weld area
- Exact text, sequence or spreadsheet
- Whether the tag will be painted or coated
- Required character height and viewing distance
- Quantity and any drawing requirements
Standard bulk tags available online

1.5 × 3-inch matching tags
Repeat the same identification, ownership wording or equipment information across the order.

1.5 × 3-inch sequential tags
Use a consecutive number range, prefix and numbering format for organized identification.
Matching, sequential and smaller formats are also available in related sizes. Projects with different text on every tag, custom dimensions, logos or unusual holes can be quoted from an approved spreadsheet or drawing.
Request a weld-on identification mockup
Send the required wording or spreadsheet, approximate dimensions, material or finish, hole pattern, mounting method and quantity. Include a photo or drawing of the installation when available. We can prepare a layout mockup and bulk quote.
