Hemaokang Steel (Shandong) Co., Ltd. is proud to present our high-quality Carbon Steel Plate A283 Gr C in thicknesses of 10mm, 12mm, and 15mm, specifically engineered for shipbuilding and offshore platform applications. As a newly established yet rapidly growing enterprise with an annual export value of US$50 million – US$100 million, we combine advanced manufacturing techniques with rigorous quality control to deliver steel plates that meet the demanding requirements of marine and offshore environments. Our A283 Gr C plates offer excellent weldability, formability, and structural integrity, making them a reliable choice for hull construction, deck structures, and offshore support systems.
Product Features & Technical Specifications
- Material & Grade: ASTM A283 Grade C – a carbon steel plate with moderate strength and outstanding toughness, ideal for structural applications where low to intermediate tensile strength is required.
- Thickness Options: Available in 10mm, 12mm, and 15mm, with custom thicknesses available upon request to suit specific project needs.
- Dimensional Flexibility: Standard widths range from 1500mm to 3000mm, and lengths from 6000mm to 12000mm. Custom dimensions can be accommodated to reduce waste and optimize fabrication.
- Surface Treatment: Plates can be supplied in black (mill finish), shot blasted, or primed surface to protect against corrosion during transport and storage.
- Mechanical Properties: A283 Gr C offers a minimum yield strength of 205 MPa (30 ksi) and tensile strength of 380–515 MPa (55–75 ksi), ensuring reliable performance under heavy loads.
- Weldability & Formability: The steel’s low carbon content and balanced chemistry allow for easy welding, cutting, and bending, reducing fabrication time and cost.
| Parameter | Value |

| Standard | ASTM A283 |
| Grade | Gr C |
| Yield Strength (min) | 205 MPa |
| Tensile Strength | 380–515 MPa |
| Elongation (in 200mm) | ≥ 21% |
| Carbon Content | ≤ 0.24% |
Key Advantages for Shipbuilding & Offshore Platforms
- High Structural Reliability: The controlled chemistry and consistent mechanical properties of A283 Gr C ensure that the plates can withstand the harsh conditions of marine environments, including wave impact, temperature variations, and cyclic loading.
- Cost-Effective Solution: Compared to higher-strength grades, A283 Gr C offers a balanced performance-to-cost ratio, making it an economical choice for non-critical structural components.
- Easy Processing: The excellent weldability allows for efficient joining of sections, while good formability enables complex shapes without cracking.
- Certified Quality: Our production facility is ISO9001:2015 certified, ensuring that every plate undergoes strict inspection and testing, including ultrasonic testing, chemical analysis, and mechanical property verification.
- Global Reach: With a team of 51–100 experienced employees and exports covering North America, South America, Europe, Asia, Africa, and Oceania, we have the capacity to fulfill large-scale orders with timely delivery.

Frequently Asked Questions
-
What is the difference between A283 Gr C and A36?
Both are carbon steel plates, but A283 Gr C has slightly lower yield strength (205 MPa vs 250 MPa for A36). A283 Gr C is often preferred for less demanding structural applications where cost savings are important, while A36 is used for general structural purposes. For shipbuilding, A283 Gr C is commonly specified for non-critical parts. -
Can these plates be used for offshore platform topsides?
Yes, A283 Gr C plates are suitable for secondary structures, walkways, and non-load-bearing components. For primary load-bearing members, higher-strength grades like ASTM A572 or ABS EH36 may be required. Always consult your design engineer. -
Do you provide mill certificates?
Yes, we supply mill test certificates (MTC) for each heat number, showing chemical composition and mechanical properties. Third-party inspection reports are also available upon request. -
What surface treatments do you offer for corrosion protection?
We provide shot blasting (SA 2.5) and primer coating (e.g., zinc-rich or epoxy) to protect the plates during transit and storage. Please specify your requirements when ordering. -
What is the minimum order quantity (MOQ)?
Our MOQ for standard sizes is 25 metric tons per thickness. For non-standard dimensions, the MOQ may be higher. We also accept trial orders for small quantities to evaluate quality. -
How long does delivery take?
For standard thicknesses and sizes, delivery takes approximately 15–25 days after order confirmation. For custom dimensions or large volumes, lead time may be 30–45 days. We can arrange express shipping for urgent orders. -
Do you offer cutting and processing services?
Yes, we can provide cutting-to-size, bevelling, and drilling services at our facility. Please contact us with your specific requirements. -
Can you supply plates with certified ABS or DNV class approval?
While our standard A283 Gr C plates are produced to ASTM A283, we can arrange for class society inspection (ABS, DNV, Lloyd's) at an additional cost. Please inquire for details.
Contact us today for a competitive quotation or to request samples. Our team is ready to support your shipbuilding and offshore projects with high-quality carbon steel plates that deliver performance and value.
