Product Details
14 gauge stainless steel sheet metal is a commonly used thickness in industrial fabrication, offering a balance between strength and formability. It is widely applied in construction, machinery manufacturing, food equipment, transportation, and general engineering structures.
The nominal thickness of 14 gauge stainless steel sheet is approximately 1.90 mm (0.075 inch), but actual dimensions may vary slightly depending on different international standards.
Thickness and Gauge Conversion
| Gauge System | Thickness (mm) | Thickness (inch) | Typical Tolerance Range |
|---|---|---|---|
| US Standard (ASTM) | 1.90 mm | 0.075 in | ±0.08 mm to ±0.15 mm |
| Imperial Gauge Reference | 14 gauge | 0.075 in | Varies by standard |
| Metric Approximation | 1.90 mm | — | Based on manufacturing standard |
Common Sheet Sizes by International Standards
Different regions and standards define stainless steel sheet dimensions based on production and application requirements.
Standard Sheet Dimensions
| Standard System | Common Width (mm) | Common Length (mm) | Notes |
|---|---|---|---|
| ASTM / US Standard | 1000 / 1219 / 1250 / 1500 | 2000 / 2438 / 2500 / 3000 / 6000 | Widely used in North America |
| EN / European Standard | 1000 / 1250 / 1500 / 2000 | 2000 / 2500 / 3000 / 6000 | Common for structural and industrial use |
| JIS / Japanese Standard | 1000 / 1219 / 1500 | 2000 / 2438 / 3000 | Frequently used in machinery and automotive sectors |
| GB / Chinese Standard | 1000 / 1219 / 1500 / 1800 / 2000 | 2000 / 2438 / 3000 / 6000 | Covers both metric and industrial requirements |
Coil and Cut Sheet Formats
14 gauge stainless steel sheet metal is available in two main supply forms:
- Coil form for continuous processing and mass production
- Cut sheet form for direct fabrication and structural use
Typical coil specifications:
- Inner diameter: 508 mm or 610 mm
- Outer diameter: depends on coil weight and processing line
- Width range: 1000 mm to 2000 mm standard
Dimensional Tolerances
| Item | Standard Requirement |
|---|---|
| Thickness tolerance | ±3% to ±6% depending on standard |
| Width tolerance | ±2 mm to ±5 mm |
| Length tolerance | ±5 mm to ±10 mm |
| Flatness | Controlled within industry deformation limits |
Surface Finish Standards
Stainless steel sheet metal is also classified by surface treatment standards:
- 2B finish: standard cold-rolled matte surface
- BA finish: bright annealed reflective surface
- No.4 finish: brushed decorative surface
- No.8 finish: mirror polished surface
- HL finish: hairline directional finish
These finishes are defined consistently across ASTM, EN, and JIS systems with minor regional variations.
Application-Driven Size Selection
Different industries prefer different standard sheet sizes:
- Construction industry: 1219 mm × 2438 mm, 1500 mm × 3000 mm
- Industrial equipment: 1000 mm × 2000 mm for precision fabrication
- Transportation industry: custom widths up to 2000 mm
- Kitchen equipment: smaller sheets for easy forming and welding
