There is equipment to do the peeling and polishing of bar surface when requirements for outer surface and accuracy of geometry are very high. After peeling process is applied the length of rolled products is 6–12 m.

Operation Operation purpose Accessible minimum diameter tolerance
Peeling of rolled bars Obtain diameter according to contract requirements and standards. Upon agreement: beveling on two sides at angle of 30°–45°±1° depth 1–5 mm. Minimum diameter tolerance:
accuracy degree h9, - Ø20-30 mm - +0/-0,052 mm, - Ø31-50 mm - +0/-0,062 mm, - Ø51-80 mm - +0/-0,074 mm accuracy degree h11, - Ø20-30 mm - +0/-0,130 mm, - Ø31-50 mm - +0/-0,160 mm, - Ø51-80 mm - +0/-0,190 mm
Polishing of rolled bars Obtain straightness of rolled bars and required surface roughness. Minimum roughness parameter (Ra) — 2,5 μm.
Bar coating with anticorrosive material Increase corrosion resistance when in transit and during storing not less 3 months.
Bars packing in polymer Mechanical damage and direct moisture protection. Upon agreement: cardboard insertions under strapping (to prevent damage of the surface). Winding density choice depending on the conditions of transportation.
