The purpose of the peeling and polishi×‍♣∏ng process is to remove decπσ€✘arburized layer and surface rolling de♥✘★fect on anchor bars，anφ∑πσd to guarantee the sγ₹εteel bars' out-of- roundness n•∞€ot more than 0.05mm

A、peeling: to ensure $÷remove decarburized layerβ♣♠"(Total layer’s de ​pth is 0mm) and surface rolling d •✔efect.

B. Polishing：Improve t×★  he surface smoothness (rou¶↓gh≤3.0μm) of steel bars

C. For traceablity, after polis★∏×hing qualifed,on each bar's top end,w™→ithin 50mm to top, mark the last 6 prπ‍≤®oduction numbers by l×&aser marking machine for traceabl&♥™✔ity.
