Pickled & Oiled Hot Rolled Steel Coil

01. Product Overview

When hot rolled steel needs a cleaner surface before further processing, pickling and oiling provide two practical benefits: removing mill scale and reducing oxidation during storage and transportation.

Our Pickled & Oiled Hot Rolled Steel Coil (HRPO Steel Coil) is made from hot rolled carbon steel. Acid pickling removes the iron oxide scale formed during hot rolling, while a rust-preventive oil coating provides temporary surface protection.

Compared with untreated black hot rolled steel coil, HRPO steel coil offers a cleaner starting surface for cutting, bending, welding, stamping and other fabrication processes. It also reduces the need for separate mill-scale removal before subsequent operations that require a cleaner steel surface.

We supply steel coil products for metal fabrication, machinery manufacturing, automotive components, steel tube production, industrial equipment and other carbon steel applications.

02. Product Specifications & Selection

The right steel coil starts with the correct grade and dimensions. We organize order requirements around material properties, processing conditions and finished-product specifications.

Steel Grade Selection

For general fabrication, steel grade selection should reflect the required strength and forming conditions. For stamping and bending, yield strength, tensile strength and elongation are important considerations. For welding applications, the selected grade and material thickness should be compatible with the intended fabrication process.

Coil Dimension Selection

Thickness and width should match the required finished dimensions and processing equipment. Coil ID, OD and weight also affect decoiling, lifting, storage and material handling. For repeat orders, consistent grade, dimensions and surface requirements help simplify incoming inspection and material planning.

03. Surface Treatment & Processing Applications

Acid-Pickled Surface

Acid pickling removes the iron oxide scale formed during hot rolling, leaving a cleaner metal surface. This is useful before cutting, bending, welding and other fabrication operations. Depending on the downstream process, additional cleaning or surface preparation may still be required.

Rust-Preventive Oil Coating

The oil coating helps reduce oxidation during storage and transportation. Oil type and specified coating weight can be included in the order requirements. This coating provides temporary protection rather than permanent corrosion resistance. Additional cleaning or preparation may be needed before painting, bonding or other surface-finishing processes.

Typical Applications

Final material selection depends on the required steel grade, thickness, mechanical properties and manufacturing process.

04. Customization & Order Specifications

We coordinate material, dimensions and surface treatment requirements according to each order.

Steel Grade and Dimensions

• Steel grade and applicable standard.
• Nominal thickness and width.
• Required thickness and width tolerances.
• Coil ID, OD and target coil weight.
• Mill edge or slit edge requirements.

Surface Treatment

• Pickled surface condition.
• Rust-preventive oil requirements.
• Oil type and specified coating weight.
• Skin Pass requirements, subject to availability.

Further Processing

• Slitting requirements.
• Cutting requirements.
• Decoiling requirements, subject to confirmed processing capability.

For special dimensions or surface requirements, we review specifications before order confirmation. This helps align material requirements with the intended application and downstream processing conditions.

05. Why Work With Shanxi Midas Industrial Co.,Ltd?

Across our steel products business, we also provide product consultation, specification communication, order confirmation, production and inspection information updates, and after-sales support throughout the purchasing process.

06. Packaging & Bulk Supply

Steel coil packaging needs to account for handling, storage and transportation conditions. Moisture exposure and mechanical damage are important considerations when arranging export shipments.

Order packaging requirements can cover:

• Coil surface protection.
• Rust-preventive packaging.
• Steel strapping and coil securing.
• Inner and outer packaging.
• Coil identification and batch marking.
• Loading and transportation arrangements.

Before shipment, coil dimensions, weight, packaging and loading requirements should be coordinated with the destination and receiving facilities.

For bulk orders, confirming steel grades, dimensions, quantities and destination requirements helps establish clear material and shipping specifications.
