SS sheet gauge is a traditional but widely used system for defining stainless steel sheet thickness. It is especially common in fabrication and industrial design where quick identification is needed.
Key takeaways:
- Gauge indicates thickness (higher number = thinner sheet)
- 18–20 gauge is most common for general stainless steel fabrication
- Millimeter measurement is more precise and widely used in international trade
- Gauge is mainly used for cold rolled stainless steel sheets

- Descrição
SS sheet gauge refers to the standardized system used to describe the thickness of stainless steel sheets (SS sheets). Unlike metric measurement (milímetros), gauge is an older industrial unit widely used in metal fabrication, fabricação, and procurement.
The key point is:
- Higher gauge number = thinner sheet
- Lower gauge number = thicker sheet
No entanto, gauge values are not perfectly linear and can vary slightly by standard system (US gauge is most commonly used in global stainless steel trade).
Stainless Steel Sheet Gauge to Thickness Conversion Table
| Medidor (US) | Grossura (milímetros) | Grossura (polegada) | Uso Comum |
|---|---|---|---|
| 26 medidor | 0.48 milímetros | 0.019 em | Light panels, uso decorativo |
| 24 medidor | 0.61 milímetros | 0.024 em | Painéis interiores, equipamento de cozinha |
| 22 medidor | 0.76 milímetros | 0.030 em | Fabricação geral, eletrodomésticos |
| 20 medidor | 0.91 milímetros | 0.036 em | Structural light-duty panels |
| 18 medidor | 1.21 milímetros | 0.048 em | Equipamento industrial, pias |
| 16 medidor | 1.52 milímetros | 0.060 em | Fabricação pesada |
| 14 medidor | 1.90 milímetros | 0.075 em | Componentes estruturais |
| 12 medidor | 2.66 milímetros | 0.105 em | Industrial plates |
| 10 medidor | 3.42 milímetros | 0.135 em | Heavy industrial use |
| 7 medidor | 4.76 milímetros | 0.188 em | Thick structural parts |
| 4 medidor | 6.35 milímetros | 0.250 em | Heavy plates, maquinaria |
Gauge vs Metric Thickness (Diferença Chave)
Most international stainless steel production uses milímetro (milímetros) grossura, while gauge is mainly used in:
- North America
- Some industrial fabrication sectors
- Legacy engineering drawings
Conversion Relationship
- Gauge is an approximate classification
- mm is an exact measurement standard
Por exemplo:
- 16 gauge ≈ 1.52 milímetros
- 18 gauge ≈ 1.21 milímetros
- 20 gauge ≈ 0.91 milímetros
Why Gauge is Still Used in Stainless Steel Industry
1. Industry Tradition
Many fabrication shops and engineering drawings still specify gauge instead of millimeters.
2. Quick Identification
Gauge allows fast identification of sheet thickness without precise measurement.
3. Standard Fabrication Practices
Certain industries standardize materials by gauge for consistency in production.
Cold Rolled vs Hot Rolled in Gauge System
Gauge is mostly used for cold rolled stainless steel sheets, while hot rolled products are typically described in millimeters.
| Tipo | Typical Thickness Representation |
|---|---|
| Cold Rolled SS Sheet | Medidor (por exemplo, 16 ga, 18 ga) or mm |
| Hot Rolled SS Plate | mm only (por exemplo, 3 milímetros, 6 milímetros, 10 milímetros) |
