HRPO Sheet Supplier Mumbai | Hot Rolled Pickled & Oiled Sheets Standard size 8x4 Ft | Aero Enterprises
Aero Enterprises supplies HRPO sheets across India for laser cutting, welding, bending, panel work, enclosures, and general fabrication. These sheets are used where a clean hot rolled surface helps reduce surface preparation before further processing.
Details of HRPO Sheet
Aero Enterprises stocks HRPO sheets (Hot Rolled Pickled and Oiled sheets) in Mumbai a processed variant of hot rolled steel where the mill scale is removed by acid pickling and the surface is oiled to prevent rust. The result is a clean, smooth, scale free surface that is ready for CNC laser cutting, plasma cutting, powder coating, painting, and precision welding without sandblasting or surface prep. These sheets are ideal for high-precision Sheet Metal Bending and Powder Coating at youe factory. Available in 8 feet x 4 feet (2440mm x 1220mm) from 0.5mm to 6mm thickness in Quality. Supplied to panel board manufacturers, automotive fabricators, electrical enclosure makers, and general engineering workshops across Mumbai, Navi Mumbai, Thane, and Vasai.

What is HRPO Sheet? HRPO Full Form and Meaning
HRPO sheet full form is Hot Rolled Pickled and Oiled sheet. Standard hot rolled (HR black) steel has a rough mill scale a layer of iron oxide on its surface from the high-temperature rolling process. HRPO sheets are HR sheets that have been through two additional steps: (1) Pickling the coil is passed through an acid bath (hydrochloric or sulfuric acid) that dissolves and removes the mill scale, leaving a clean silver-grey surface, and (2) Oiling a thin layer of oil is applied immediately after pickling to prevent flash rusting during storage and transport. The final product has no mill scale, better surface flatness than HR black, and is dimensionally the same as hot rolled. HRPO is not the same as cold rolled (CR) HRPO has the thicker tolerances and higher roughness of hot rolling, but with a clean surface. Think of HRPO as 'HR sheet without the scale problem.' It sits between HR black and CR in the quality/cost hierarchy: better surface than HR black, lower cost than CR.

HRPO Sheet vs HR Black vs CR Sheet What is the Difference?
HR Black sheet has rough mill scale requires sandblasting or grinding before painting or welding. HRPO sheet has the same base steel but scale is removed by pickling clean surface ready for immediate powder coating, laser cutting, or welding. CR sheet (CRCA) has smooth, bright finish with tight tolerances (±0.05mm) but costs 10 to 12% more than HRPO. HRPO is the ideal middle ground: cleaner than HR black for surface-critical applications, cheaper than CR where mirror-smooth finish is not required. HRPO vs HR: HRPO costs 3 to 5% more than HR black due to pickling processing, but eliminates costly surface prep labor. For laser-cut control panels, switchgear, and powder-coated fabrications, HRPO is the most cost-effective starting material.
HSN Code of HRPO Sheet
HSN code for HRPO sheet (hot rolled pickled and oiled, width 600mm+) is 7208. 8-digit HSN: 72082700 for thickness 4.75mm and above, 72083700 for 3mm to 4.75mm, 72085200 for thinner gauges. GST rate: 18%. HRPO sheets import/export under the same HS code as HR black sheets - the pickling process does not change the classification. All Aero Enterprises invoices carry 8-digit HSN and GST breakup.
