Hot Rolled Carbon Steel Plate with 6mm - 700mm Thickness in ASTM A36 / JIS SS400 / GB Q235 and Wear Resistant NM450 / NM500 Grades

We supply hot rolled carbon steel plates (black iron sheets) in a wide range of grades including:

• ASTM A36 / A283 / A516
• JIS SS400 / SPHC / S235JR
• GB Q235 / Q345
• High strength & wear-resistant grades: NM450 / NM500

These plates are widely used in construction, shipbuilding, machinery manufacturing, pressure vessels, bridges, and structural engineering.

Industries require steel materials that provide:

• High structural strength
• Excellent weldability and machinability
• Cost efficiency for large-scale projects
• Durability under heavy load conditions

Stainless steel is unnecessary for many structural uses, so carbon steel becomes the most economical and practical choice.

We offer a full range of hot rolled steel plate solutions:

• Multiple grades: A36, SS400, Q235, Q345, S235JR, S355, etc.
• Thickness range: 6mm – 700mm (customizable)
• Width range: 500mm – 4020mm
• Length: up to 18800mm (custom cut available)
• Surface: black / pickled / blasted / coated
• Processing: cutting, welding, drilling, bending available
• High-strength wear-resistant options (NM450 / NM500)

Hot rolled carbon steel plates are widely used in:

1. Building and construction structures
2. Bridges and infrastructure projects
3. Shipbuilding and marine engineering
4. Pressure vessels and boilers
5. Heavy machinery manufacturing
6. Automotive and industrial components
7. Mining and wear-resistant equipment (NM450 / NM500)

• Steel billet preparation
• Heating to high temperature
• Hot rolling into plate form
• Controlled cooling
• Surface finishing (black / pickled / blasted)
• Straightening and cutting
• Quality inspection and certification
• Export packaging and shipping

• A36 / SS400 / Q235 → General construction, low cost structural use
• S235JR / S355 → European standard, higher strength structures
• Q345 → Medium-high strength engineering use
• A516 → Pressure vessels and boilers
• NM450 / NM500 → Wear-resistant applications (mining, heavy equipment)
• Thickness guide:
• 6–20mm → light structural use
• 20–60mm → heavy construction
• 60mm+ → industrial heavy-duty engineering
