Hot Rolled Steel Coils
01. Product Overview
Choosing the right hot rolled steel coil means matching the steel grade, dimensions, and surface condition to the next manufacturing process. Our hot rolled carbon steel coils are supplied for structural fabrication, welded pipe manufacturing, steel processing, machinery production, and general metal fabrication.
We offer multiple steel grade options, including Q195, Q235, Q345, A36, S235JR, S275JR, S355JR, SPHC, and SPHD. Customers can also select between as-rolled black surface and pickled and oiled finishes according to their processing requirements.
Key Product Features
- Multiple Steel Grade Options: Carbon structural steel and selected higher-strength grades cover different fabrication and structural requirements.
- Two Surface Conditions: Black surface coils retain their hot-rolled oxide scale, while pickled and oiled coils provide a cleaner surface for subsequent processing.
- Processing Options: Slitting and cut-to-length processing are available as listed options for customers requiring narrower strips or specified sheet lengths.
- Specification-Based Supply: We coordinate steel grade, standard, thickness, width, and coil weight requirements for individual orders.

Steel Grade Selection
- Carbon Structural Steel: Q195, Q235, A36, S235JR, and S275JR are listed options for structural and general fabrication requirements, subject to their respective standards.
- Higher-Strength Steel: Q345 and S355JR are options for applications requiring specified strength levels.
- Forming Applications: SPHC and SPHD are available steel grade options for forming and downstream processing applications.
- Standard Requirements: ASTM, EN, JIS, and GB/T requirements should be confirmed against the exact grade and product specification. Similar grade designations across different standards should not be treated as automatically equivalent.
Dimensional Selection
Thickness and width should match the requirements of the finished product and processing equipment. Coil weight, inner diameter, outer diameter, and dimensional tolerances also affect transportation, storage, and production handling.
03. Surface Conditions & Processing Options
Surface condition affects the preparation required before welding, forming, fabrication, or finishing. We offer two main surface options to match different downstream requirements.
As-Rolled Hot Rolled Steel Coils
As-rolled coils retain the oxide scale formed during hot rolling. They are suitable for applications where the original hot-rolled surface is acceptable, including general structural fabrication, welded pipe manufacturing, and steel processing.
Pickled and Oiled Hot Rolled Steel Coils
Pickling removes the oxide scale formed during hot rolling, while the subsequent oil coating provides temporary protection against surface corrosion during storage and transportation. This surface condition is suitable for applications requiring a cleaner steel surface before further forming, fabrication, or finishing.
Available Processing Options
- Slitting: Converts wider steel coils into narrower strips for downstream manufacturing.
- Cut-to-Length: Converts coil material into specified sheet lengths.
- Dimensional Requirements: Customers can submit their required thickness, width, and individual coil weight for supply evaluation.
04. Hot Rolling Process & Quality Control
The hot rolling process determines the steel coil's final dimensions, surface condition, and material properties. We focus on matching supplied products with the specified grade and order requirements.
Hot Rolling Process
Steelmaking: Establishing the chemical composition required for the selected steel grade.
Slab Heating: Heating steel slabs before the rolling process.
Hot Rolling: Reducing slab thickness through rolling to obtain the required coil dimensions.
Cooling and Coiling: Cooling the rolled steel and winding it into coils.
Final Inspection: Checking dimensions, surface condition, and specified material properties.
Key Quality Inspection Items
- Chemical Composition: Carbon, manganese, silicon, phosphorus, and sulfur.
- Mechanical Properties: Yield strength, tensile strength, and elongation according to the applicable standard.
- Dimensional Accuracy: Thickness, width, and specified dimensional tolerances.
- Surface Condition: Inspection for visible defects and unacceptable surface conditions.
- Material Traceability: Mill Test Certificates (MTC) for material identification and verification of specified properties, subject to order documentation.
These inspection items provide a practical basis for checking whether the supplied steel coil matches the agreed purchasing specification.
