Hot Rolled Mild Steel Sheets

Hot rolled mild steel sheets are extensively used across construction, infrastructure, and manufacturing sectors owing to their affordability, robust mechanical properties, and ease of fabrication. Produced at elevated temperatures, these sheets are best suited for applications where high strength is required, and precision surface finish is not a primary concern.

Why Use Hot Rolled Mild Steel Sheets?

High strength – Delivers excellent load-bearing capacity for structural and heavy-duty applications.
Cost-effective – Economical choice for large-scale projects, offering value without compromising performance.
Good weldability – Readily cut, welded, and shaped, allowing flexibility in fabrication.
Versatility – Used in everything from building frames and bridges to pipelines and heavy machinery.
Custom sizes available – Offered in a variety of thicknesses and dimensions tailored to your application.

Manufacturing Process of Hot Rolled Steel Sheets

Hot rolled sheets are made by heating steel beyond its recrystallisation point—typically above 927°C—and then rolling it to the required thickness. The process includes:

Heating – Steel slabs are raised to high temperatures in a reheating furnace.
Rolling – Heated slabs are flattened through rolling mills to achieve desired thickness and width.
Cooling – Sheets are left to cool naturally at room temperature, forming a scaled surface.
Finishing – Depending on the intended application, sheets may undergo pickling or descaling.

This process enhances the ductility and formability of the steel, making it ideal for structural and general-purpose fabrication.

Hot Rolled Steel Grades Available

Our range of hot rolled sheets meets major Indian standards to ensure safety, consistency, and suitability for industrial use:

IS 2062 – For structural applications in construction and general engineering.
IS 10748 – For use in automotive and general mechanical engineering.
JSW grades – Proprietary grades developed by JSW Steel to meet specific technical and commercial requirements.

Applications of Hot Rolled Mild Steel Sheets

Construction – Used in structural components such as beams, columns, purlins, and base plates.
Fabrication – Frames, brackets, structural supports, and custom assemblies.
Automotive – Chassis components, mounting brackets, and suspension arms.
Industrial use – Tanks, pressure vessels, ducts, and mechanical casings.
Shipbuilding – Essential in hull fabrication, decks, bulkheads, and support plates.

FAQs

How are hot rolled sheets different from cold rolled sheets?
Hot rolled sheets have a coarse finish and are less precise dimensionally, making them more suitable for structural and heavy fabrication tasks. Cold rolled sheets, on the other hand, are used when tight tolerances and a smoother finish are required.
Can hot rolled mild steel sheets be customised?
Yes. JSW One MSME provides hot rolled sheets in custom widths, lengths, and thicknesses to suit your exact specifications.
What thicknesses are typically available?
Thicknesses generally range from 1.2 mm-25 mm, though bespoke dimensions can also be arranged on request.
Are hot rolled sheets easy to weld and cut?
Absolutely. These sheets have excellent machinability, enabling straightforward cutting, bending, drilling, and welding.
How should these sheets be stored?
To preserve quality, store sheets in a dry, covered area away from moisture and corrosive elements.
Can hot rolled steel be used for load-bearing structures?
Yes, especially sheets that conform to IS 2062 standards, which are engineered for high-strength applications.
Do hot rolled sheets rust faster than other steels?
Because of their scaled surface, they may oxidise more quickly than treated steel. Galvanisation or painting is advised for long-term exposure.
What are the typical widths and lengths offered?
Standard widths range from 1000 mm to 2000 mm, with lengths from 2000 mm up to 6000 mm or cut-to-size.
What industries use hot rolled sheets the most?
Key users include construction, transport, heavy engineering, fabrication shops, and shipbuilding.
Is test certification provided with each batch?
Yes. Material Test Certificates (MTCs) are supplied for traceability and compliance assurance.
What finishing options are available?
Common finishes include mill scale and pickled-and-oiled, depending on application needs.
How is delivery handled for bulk orders?
JSW One MSME offers pan-India logistics with flexible dispatch scheduling for large-scale or just-in-time deliveries.
Are these sheets environmentally sustainable?
Yes. Hot rolled steel sheets are fully recyclable, aligning with green building and circular economy initiatives.
Can these sheets be used for export-oriented fabrication?
Certainly. JSW hot rolled sheets comply with international standards and are suitable for global manufacturing supply chains.
What are the lead times for delivery?
Delivery times depend on quantity and customisation, though most standard orders are fulfilled within 5–10 working days.
