Explore Our Hot Rolled Steel Series

Hot rolled steel is the cornerstone of modern heavy industry. Manufactured at extreme temperatures, it offers excellent formability, weldability, and structural integrity at a highly cost-effective price point. It is the material of choice for applications where precise dimensional tolerances and flawless surface finishes are secondary to sheer strength and durability.

At Luyuan Steel, we supply a comprehensive range of hot rolled products, including coils (HRC), flat sheets, and solid rods. From standard structural carbon steel (A36, SS400, Q235) to specialized alloy and pressure vessel grades (SA516 Gr.60), we deliver materials that meet rigorous international standards.

Sıcak Haddelenmiş Çeliği Neden Luyuan’dan Tedarik Etmelisiniz?

  • Sıcak Haddelenmiş Çelik için Kapsamlı Kalite Seçimi

    Comprehensive Grade Selection

    We stock and supply a vast array of steel grades. Whether you need standard S235JR for general construction, high-strength Q345/S355 for load-bearing structures, or specialized SA516 for boiler plates, we have the right material for your application.

  • Sıcak Haddelenmiş Çelik için Ağır Hizmet Tipi Ölçüler

    Heavy-Duty Dimensions

    Our supply capabilities cover everything from 1.2mm thin coils to massive 100mm thick heavy plates and 300mm diameter forged rods, meeting the extreme demands of shipbuilding, mining, and heavy infrastructure.

  • Sıcak Haddelenmiş Çelik için Asitlenmiş ve Yağlanmış (P&O)

    Pickled & Oiled (P&O) Options

    For applications requiring a cleaner surface without the cost of cold rolling, we offer Pickled and Oiled (P&O) hot rolled steel. This process removes the mill scale, providing a superior surface for painting, welding, and laser cutting.

  • Sıcak Haddelenmiş Çelik için Gelişmiş İşleme Hizmetleri

    Advanced Processing Services

    We don't just supply raw materials; we deliver semi-finished components. Our processing center offers precision decoiling, leveling, slitting, plasma/laser cutting, and bending, significantly reducing your in-house fabrication time.

  • Sıcak Haddelenmiş Çelik için Garantili İzlenebilirlik

    Guaranteed Traceability

    Every batch of hot rolled steel is fully traceable. We provide comprehensive Mill Test Certificates (MTC) detailing the chemical composition and mechanical properties, ensuring full compliance with your project's engineering specifications.

Custom Processing — Ready for Fabrication

Reduce your production bottlenecks by utilizing our comprehensive steel processing and customization services:

Decoiling & Leveling Flattening HR coils into precise sheets with high flatness tolerances
Slitting & Cutting Slitting coils into narrow strips; plasma and laser cutting plates to custom profiles
Yüzey İşlemi Shot blasting to remove mill scale; applying protective oil coatings
Rod Processing Precision cutting of hot rolled rods; chamfering and basic machining
Testing Standard or high-strength structural grades
Base Metal Ultrasonic testing (UT) for heavy plates to detect internal flaws
Sıcak Haddelenmiş Çelik için Özel İşleme

Send us your CAD drawings or material lists, and we will deliver steel that is ready for immediate assembly.

Sıkça Sorulan Sorular

  • What is the difference between Hot Rolled and Cold Rolled steel?

    Hot rolled steel is rolled at high temperatures (over 1,700°F), which makes it easier to form and cheaper to produce, but it leaves a rough, scaly surface (mill scale) and has slightly looser dimensional tolerances. Cold rolled steel is hot rolled steel that has been further processed at room temperature to achieve precise dimensions, a smooth finish, and higher strength.

  • When should I choose Pickled and Oiled (P&O) hot rolled steel?

    If your manufacturing process involves precise welding, laser cutting, or painting, standard hot rolled steel’s mill scale can cause issues. The pickling process removes this scale using acid, and the oil prevents flash rusting. P&O steel offers a cleaner surface similar to cold rolled steel, but at a lower cost.

  • Can you supply heavy plates with Ultrasonic Testing (UT)?

    Yes. For critical applications like pressure vessels, offshore platforms, and heavy load-bearing structures, we can supply thick hot rolled plates that have undergone Ultrasonic Testing (UT) to ensure there are no internal laminations or defects.
