Product Advantages & Benefits
- Excellent Weldability: ASTM A36 carbon steel is known for its superior weldability, making it ideal for welding fabrication projects. The 20mm thickness provides a robust base for structural joints without compromising integrity.
- High Strength-to-Weight Ratio: With a minimum yield strength of 250 MPa, these plates offer reliable support for heavy loads while remaining manageable for fabrication and installation.
- Versatile Application: Perfect for structural components such as beams, columns, bridge parts, industrial machinery frames, and general construction. The 20mm thickness is particularly suitable for medium-duty structural applications.
- Dimensional Accuracy: Our plates are precision-cut to tight tolerances, ensuring consistent thickness and flatness. This reduces waste and improves efficiency during cutting, welding, and assembly.
- Customizable Sizes: We offer width and length customization to meet your specific project requirements. Available in standard sizes or tailored dimensions upon request.
- ISO9001 Quality Assurance: Every plate is produced under a strict quality management system, ensuring traceability and compliance with international standards.
- Cost-Effective Solution: Compared to higher-grade alloy steels, ASTM A36 provides an excellent balance of performance and cost, making it a preferred choice for budget-conscious projects without sacrificing quality.
Industrial Applications
This carbon steel plate is widely used in:
- Welded structural steel frames for buildings and warehouses
- Bridges, highway structures, and transmission towers
- Industrial equipment bases, supports, and brackets
- Shipbuilding and offshore platforms (non-critical structural parts)
- Heavy machinery components and agricultural equipment
- General fabrication projects requiring reliable weldability
