Q235 Q345 ASTM Hot Rolled Carbon Steel Plate 0.5–850mm Carbon Steel Sheet for

Hot Rolled Carbon Steel Plate is a versatile structural material widely used in construction, heavy equipment, shipbuilding, pressure vessels, machinery manufacturing, and steel fabrication. Manufactured according to ASTM, AISI, GB, JIS, DIN, and BS standards, these carbon steel plates are available in multiple grades, including Q235, Q345, A36, SS400, S235, and S355.

Our hot rolled carbon steel plates are supplied in thicknesses from 0.5 mm to 850 mm, widths up to 6500 mm, and customized lengths to meet diverse engineering requirements. Processing services such as cutting, bending, welding, punching, and decoiling are available to reduce secondary fabrication costs.

Selecting the correct carbon steel plate is critical because different projects require specific combinations of:

• Structural strength
• Plate thickness
• Fabrication capability
• Welding performance
• Dimensional tolerance
• Applicable international standards

Using an unsuitable steel grade or incorrect dimensions may increase fabrication costs or fail to meet project specifications.

Our hot rolled carbon steel plates provide flexible material options for structural and industrial projects. Key solutions include:

• Multiple grades including Q235, Q345, A36, SS400, S235, S355
• Thickness from 0.5 mm to 850 mm
• Width up to 6500 mm
• Custom lengths according to project requirements
• Hot rolled and cold rolled processing options
• Cutting, welding, bending and punching services
• Standard export seaworthy packaging
• CE, BV and SGS certification support

These options help customers source ready-to-process steel plates that match their engineering specifications.

Hot rolled carbon steel plates are widely used in:

• Building structures
• Steel fabrication
• Shipbuilding
• Boiler manufacturing
• Pressure vessels
• Container manufacturing
• Bridge engineering
• Machinery manufacturing
• Mold and die production
• Flange fabrication
• Heavy equipment
• Industrial infrastructure

Hot rolled carbon steel plates are manufactured by rolling steel billets at elevated temperatures above the material's recrystallization point. The hot rolling process improves formability and allows the production of thicker steel plates with various dimensions.

After production, the plates can be further processed through:

• CNC cutting
• Welding
• Bending
• Punching
• Surface coating

The finished components are then assembled into structural frameworks, industrial equipment, ships, containers, and engineering projects.

1. Select the Steel Grade
   Choose grades such as Q235, Q345, A36, SS400, S235, or S355 according to your project standards and mechanical requirements.
2. Confirm Plate Dimensions
   Specify thickness, width, and length. Available sizes range from 0.5 mm to 850 mm in thickness and 100 mm to 6500 mm in width.
3. Determine Surface Finish
   Available finishes include black surface, black painted, galvanized, and color coated. Choose based on environmental exposure and downstream processing requirements.
4. Consider Processing Requirements
   If your project requires ready-to-use materials, processing services such as cutting, welding, bending, punching, and decoiling are available.
5. Verify Delivery and Certification
   Confirm certification requirements (ISO, CE, BV, SGS), packaging method, delivery schedule, and trade terms before placing an order.
