- 説明
あ 20G stainless steel sheet refers to stainless steel sheet material identified by the ゲージ (g) system, where “20G” indicates a specific thickness level. It is commonly used in HVAC systems, キッチン用品, 軽加工, 自動車部品, および産業用エンクロージャ.
In modern engineering, stainless steel sheet thickness is usually specified in millimeters (mm), while the gauge system is still widely used in North America and some industrial fields.
What Does 20 ゲージ (20g) Mean?
ゲージシステムでは:
- あ higher gauge number = thinner sheet
- あ lower gauge number = thicker sheet
20G Stainless Steel Thickness Conversion
| ゲージ | 厚さ (mm) | 厚さ (インチ) |
|---|---|---|
| 20g | 0.81 mm | 0.032 で |
👉 20G stainless steel sheet is considered a thin sheet, suitable for light structural and fabrication work.

Gauge vs Metric Thickness System
Gauge System (g)
- Common in North America
- Based on historical metal thickness standards
- Not linear (difference between gauges varies)
Metric System (mm)
- International standard
- More accurate and widely used in engineering
