Anodized Aluminum vs Stainless Steel Nameplates
Anodized aluminum and stainless steel are the two materials most buyers compare for equipment nameplates and ID plates. Both are made in our own Shenzhen factory. This guide explains how each is marked and what to tell us so we can recommend one for your plate.
1. How each one is marked
| Anodized aluminum | Stainless steel | |
|---|---|---|
| How the mark is made | Anodizing, chemical etching, screen printing or laser engraving; the mark sits inside the anodic layer rather than printed on the surface | Chemical etching (deep-etched and enamel-filled), laser marking or screen printing |
| Color | Anodized color options | Natural steel with color-filled marking |
| Grades | Aluminum, grade confirmed in the quotation | 304 or 316 stainless steel, grade confirmed in the quotation |
| Thickness | Custom to your drawing | Custom to your drawing |
2. When anodized aluminum fits
- You want a lightweight plate
- You want color in the plate itself, from our anodized color options
- Your marking can be anodized, etched, printed or laser engraved
- You need logos, text, serial numbers, barcodes or QR codes
3. When stainless steel fits
- The plate faces washdown, chemical exposure or high heat
- You want deep-etched, enamel-filled marking
- You need serial numbers or barcodes etched or laser marked on steel
- Valve tags and industrial equipment are common uses
4. Tell us where the plate will live
Material, finish and marking should be selected for the intended environment. Tell us where the plate will be mounted and the conditions it will face, and we will recommend the material and finish. Service life is confirmed for your environment, not promised as a fixed number.
