1) Wide range of diameters from 10mm to 100mm

2) Customized Length from 100mm to 12000mm

3) Good surface roughness: 0.4um to 1.5um

4) Good straightness: 0.5mm/m to 2mm/m

5) Good roundness: 80% of diameter tolerance

6) Diameter tolerance: -0.02mm to -0.06mm/h9, h10, h11

7) Matched further processing: Grinding, polishing, straightening

8) Anti-rusty package

9) Full sets of testing equipment: Surface, Dimenstion. Mechanical properties testing
