Home > Round Bars > Peeled Polished Round Bars
Inox Steel India is a trusted manufacturer, supplier, and exporter of Peeled & Polished Round Bars in carbon steel, alloy steel, and stainless steel grades, processed to achieve high dimensional accuracy, superior straightness, and smooth surface finish.
Our peeled and polished round bars are specifically developed for precision machining, hydraulic applications, rotating equipment, and critical engineering components, where tight tolerances and surface integrity are essential.
With in-house processing capability and consistent stock, Inox Steel India supplies peeled, ground, and polished round bars to OEMs, CNC machining units, and export buyers across India and global markets.
Peeled and polished round bars are steel bars that undergo a surface peeling (turning) process, where the outer decarburized and scaled layer is mechanically removed. This is followed by polishing or grinding to achieve precise diameter, smooth surface finish, and improved straightness.
Compared to hot rolled or standard bright bars, peeled & polished bars offer:
This makes them ideal for critical rotating and load-bearing components.
At Inox Steel India, peeled and polished round bars are produced through controlled and sequential processing steps to ensure uniform quality and machining reliability.
This process results in dimensionally accurate, smooth, and machining-ready bars.
These advantages make peeled & polished round bars the preferred choice for hydraulic systems, CNC machining, and critical engineering assemblies.
