Pickled and Oiled Carbon Steel Coil — Factory Direct Supplier | Huaxia-Steel
Pickled and oiled (P&O) steel coil is hot-rolled carbon steel that has been descaled in hydrochloric acid and coated with a rust-preventive oil. It combines the economy of hot-rolled coil with a clean, scale-free surface close to cold-rolled quality — the ideal input for tube mills, roll formers, and component makers who want to eliminate shot blasting from their process. Huaxia-Steel supplies P&O coil in 1.0–12.7 mm thickness, 600–2,050 mm width, in grades from Q195 to SPHC/SS400/S355 and SAE 1008–1035.
Product Overview
Hot-rolled coil arrives with a blue-grey mill scale that damages tooling and welds. In our pickling line the scale is dissolved in HCl tanks, the strip is rinsed, dried, and side-trimmed, and a uniform oil film is applied to protect the surface in transit and storage. The result is a smooth, bare-steel surface with better weldability, paintability, and dimensional precision than black HR coil, at a cost typically 3–8% above black hot rolled and well below cold rolled.

P&O vs Black Hot-Rolled vs Cold-Rolled
| Property | Hot rolled (black) | Pickled & oiled | Cold rolled (CRC) |
|---|---|---|---|
| Surface | Mill scale | Clean bare steel + oil | Bright, smooth |
| Thickness range | 1.2 mm and up | 1.0 – 12.7 mm | 0.3 – 3.0 mm typical |
| Thickness tolerance | Widest | Medium | Tightest |
| Weldability | Poor without descaling | Good as-supplied | Excellent |
| Paintability | Requires blasting | Direct painting possible | Excellent |
| Relative cost | 1.0 | 1.03 – 1.08 | 1.15 – 1.30 |
If your process currently shot-blasts HR coil before welding or forming, switching to P&O usually pays back through removed blasting cost, longer die life, and fewer weld defects — the modest coil premium is recovered within the first processing stage.
Available Grades
Manufacturing Standards and Quality Control
Pickling lines are operated under ISO 9001 with acid concentration, temperature, and line speed controlled per grade. After pickling, strip is inspected for over-pickling (rough surface), under-pickling (residual scale), stains, and holes; oil film weight is monitored for uniform protection.
Applications
Packaging and Shipping
Coils are delivered eye-to-sky on wooden skids (ISPM 15) with VCI-free but waterproof wrapping, steel banding, and edge protectors; oiling ensures 2–3 months of indoor storage protection. Containerized loads are secured against shifting. FOB, CFR, CIF, and DAP terms supported with full MTC documentation.
