20g Lembaran Keluli Tahan Karat
20G stainless steel sheet corresponds to a thickness of approximately 0.81 mm, making it a widely used thin-gauge stainless steel material. It is commonly supplied in standard sheet sizes such as 4×8 ft and 4×10 ft, and is available in grades like 304, 316, 430, dan 201.
- Penerangan
A 20G stainless steel sheet refers to stainless steel sheet material identified by the tolok (G) system, where “20G” indicates a specific thickness level. It is commonly used in HVAC systems, peralatan dapur, fabrikasi ringan, komponen automotif, and industrial enclosures.
In modern engineering, stainless steel sheet thickness is usually specified in milimeter (mm), while the gauge system is still widely used in North America and some industrial fields.
What Does 20 Tolok (20G) Mean?
Dalam sistem tolok:
- A higher gauge number = thinner sheet
- A lower gauge number = thicker sheet
20G Stainless Steel Thickness Conversion
| Tolok | Ketebalan (mm) | Ketebalan (inci) |
|---|---|---|
| 20G | 0.81 mm | 0.032 dalam |
👉 20G stainless steel sheet is considered a lembaran nipis, 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
