Warmgewalzter Stahl – HR-Coil, Blech und Stab

Get a Quote

Entdecken Sie unsere Reihe warmgewalzter Stähle

Warmgewalzter Stahl ist der Grundpfeiler der modernen Schwerindustrie. Er wird bei extremen Temperaturen hergestellt und bietet hervorragende Umformbarkeit, Schweißbarkeit und strukturelle Integrität zu äußerst wirtschaftlichen Kosten. Er ist das Material der Wahl für Anwendungen, bei denen präzise Maßtoleranzen und makellose Oberflächen wichtigerweise hinter hoher Festigkeit und Langlebigkeit zurückstehen.

Bei Luyuan Steel liefern wir ein umfassendes Sortiment warmgewalzter Produkte, darunter Coils (HRC), Flachbleche und Vollstäbe. Vom standardmäßigen unlegierten Baustahl (A36, SS400, Q235) bis hin zu speziellen Legierungs- und Druckbehälterstählen (SA516 Gr.60) liefern wir Materialien, die strengen internationalen Normen entsprechen.

Why Source Hot Rolled Steel from Luyuan?

Comprehensive Grade Selection

Wir lagern und liefern eine große Auswahl an Stahlsorten. Ob Sie Standardstahl S235JR für den allgemeinen Hochbau, hochfesten Q345/S355 für tragende Konstruktionen oder den speziellen SA516 für Kesselbleche benötigen – wir haben das passende Material für Ihre Anwendung.
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.
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.
Weiterführende Bearbeitungsdienstleistungen

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.
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
Oberflächenbehandlung	Shot blasting to remove mill scale; applying protective oil coatings
Rod Processing	Präzisionszuschnitt von warmgewalzten Stäben; Anfasen und einfache Bearbeitung
Testing	Standard or high-strength structural grades
Base Metal	Ultrasonic testing (UT) for heavy plates to detect internal flaws

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

Frequently Asked Questions

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.
Können Sie dicke Bleche mit Ultraschallprüfung (UT) liefern?

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.
