Metric Steel Sizing
Metric stainless steel is measured using the metric system—millimeters (mm), centimeters (cm), and meters (m)—rather than inches or feet. While that may seem like a minor difference, it can introduce challenges for teams more familiar with imperial sizing.
Metric stainless bars typically come in 10–12 ft lengths, though custom lengths are available. While custom sizing may increase the cost upfront, it can reduce machining time and material waste—saving time and money in the long run.
| Shape | What the Size Refers To |
|---|---|
| Rounds | Diameter in millimeters |
| Flats | Width × thickness (in mm) |
| Square Bars | Width (side-to-side), solid or hollo |
