| Diameter Range | 3mm - 300mm | Available diameter options for round bars |
| Length | 3m - 12m or custom | Standard and custom length options |
| Surface Finish | Bright, Polished, Peeled | Multiple surface treatment options |
| Straightness Tolerance | ≤1.5mm/m | High precision straightness per ASTM A108 |
| Application | Shafts, Gears, Fasteners, Machinery Parts | Typical industrial applications requiring precision |
| Certification | EN 10204 3.1, ISO 9001, Material Test Report | Quality certifications and traceability documents |
| MOQ | 5 tons | Minimum order quantity for standard grades |
Acceptable Quality with Initial Documentation Delay
Purchased 6 tons of 1018 bars, 20mm diameter for distribution inventory. Material quality met ASTM A108 standards, surface finish and dimensions within specification. Initial shipment arrived without mill test certificates, required follow-up emails over 5 days to receive documentation. Issue resolved professionally, certificates eventually provided showing compliant chemical composition. Product itself good for the price point, would order again with earlier documentation request.
