CCS A Shipbuilding Steel Plate

Supplying CCS A grade marine steel plate to shipyards and offshore fabricators. 100% compliant with China Classification Society (CCS) rules for hull construction and marine structures. Every plate comes with original Mill Test Certificate (MTC) showing CCS certification and full material traceability. Third-party inspection (SGS, BV, Lloyds) fully supported.

What is CCS A Grade Ship Plate? And Why Source from Us?

 

One-stop steel procurement

CCS A is a general strength hull structural steel approved by the China Classification Society for shipbuilding and marine engineering . It's the most commonly used grade for hull structures, bulkheads, and decks where moderate strength and excellent weldability are required.

With minimum yield strength of 235 MPa and good low-temperature toughness, CCS A is designed for shipbuilding applications that demand reliable performance in marine environments. It meets the requirements of CCS Rules for Materials and Welding – the essential standard for vessels classed with CCS.

Over the past decade, we've specialized in marine and offshore steels, supplying to shipyards across Asia, the Middle East, and Europe. We understand that shipbuilding is schedule-driven: a delay in materials means delayed delivery of the entire vessel. That's why we focus on reliable supply and complete documentation – so your project stays on track and passes class inspection without issues.

Detailed description

 

What These Numbers Mean for Your Shipyard

 

Strength - The first line of defense for ship safety

235 MPa is the "safety bottom line" for the ship structure steel set by CCS. We have controlled the yield strength within the range of 250 - 280 MPa, which not only ensures the strength of the ship structure but also avoids being too hard - too hard would cause cracking during cold bending processing, and too soft would fail to pass the ship inspection. Your workers can operate more smoothly, and the ship body curved plates can be formed in one step.

 

Welding performance – Reduce your welders' worries

The carbon content is controlled within the range of 0.16-0.18%, which is far below the standard upper limit. This indicates a wide welding process window, eliminating the need for complex preheating and post-heating treatments. Moreover, the weld seam can be dense and free of cracks, significantly enhancing the efficiency of sectional construction.

 

Formability - One-time molding of complex surfaces

A 24-28% elongation rate ensures the plastic deformation capability of the steel plate during cold bending or hot bending. Whether it's the complex curves at the bow of the ship or the straight bulkheads, the material can extend uniformly without wrinkling or cracking, reducing the need for rework.

 

Resilience - The "fatigue-resistant constitution" for coping with marine environments

The hull of the ship has to withstand the alternating loads of wind and waves at sea. Our CCS A steel plates have undergone normalizing or controlled rolling processes, resulting in refined grains and stable low-temperature impact toughness. This ensures that the ship can safely navigate even in harsh sea conditions.

1. CCS Rules Compliance
All our A grade ship plates are manufactured strictly according to CCS Rules for Materials and Welding and approved by China Classification Society for hull construction . We maintain works approval certification and each production batch follows the approved quality control plan.

2. Mill Test Certificate (MTC) with Every Plate
Every shipment comes with the original CCS-approved Mill Test Certificate showing:

Heat number and chemical analysis

Mechanical test results (yield, tensile, elongation, bend test)

CCS works approval number

Conformity statement to CCS Rules

Inspector stamp and signature

This is your essential document for:

Shipyard quality control files

CCS surveyor inspection

Vessel classification documentation

Owner handover documents

3. Third-Party Inspection – Fully Supported
We welcome and fully support pre-shipment inspection by any classification society or inspection agency:

CCS surveyors (at mill or at our warehouse)

Lloyd's Register (LR)

Bureau Veritas (BV)

DNV

American Bureau of Shipping (ABS)

SGS, Intertek, or any agency your shipyard specifies

We'll coordinate sampling, testing, and documentation – making your class approval process smooth and hassle-free.

4. Heat Number Traceability
Each plate is clearly marked with heat number, grade, and CCS stamp before shipment. You can trace every plate back to the original mill test report – essential for shipyard quality systems and future vessel maintenance.

5. Multiple Class Certifications Available
Need other class society approvals? We can also supply plates certified with:

LR (Lloyd's Register) – Grade A

BV (Bureau Veritas) – Grade A

DNV – Grade A

ABS (American Bureau of Shipping) – Grade A

NK (Nippon Kaiji Kyokai) – Grade A

User Evaluation

I have been cooperating with this supplier for four years. What gives me the greatest peace of mind is that their documents are always reliable. For each batch of CCS A steel plates, the MTC is sent along with the goods, and the CCS inspectors stamp it, with the furnace number and batch number clearly marked. Our quality department never needs to chase after them for documents because they have sent all the scanned copies before shipment, allowing us to prepare for inspection in advance.

Mr. Chen Wei

Singapore · Large Shipbuilding and Repairing Group

We have been cooperating for two years now. The journey from Haiphong Port to our shipyard takes 7 to 10 days. With all the necessary documents in place, the ship inspection was passed on the first attempt. What we need in a supplier is one who 'doesn't require my involvement'.

Ms. Nguyen Thi Hong

Haiphong · Shipbuilding Group of Vietnam

Once we urgently needed a batch of thick plates (40mm) with CCS certification. We tried several suppliers but none had them in stock. They then ordered from their inventory and delivered them to Kodik Port within a week. For our ship repair factory, time is money. With such a supplier, we could tell the shipowner, 'No problem, we can repair it.

FAQ

 

 

01.Is the CCS A ship plate you provided truly certified by CCS? Is the certificate an original one?

Yes. We hold the CCS factory approval certificate. Each batch of materials is inspected by CCS surveyors and accompanied by the original factory material certificate (MTC) stamped by CCS. You can submit this certificate to the classification society for inspection.

02.Can your CCS A type ship plates be used for international navigation vessels?

OK. CCS is a formal member of the International Association of Classification Societies (IACS). Materials certified by CCS are accepted by the major flag states worldwide and can be used for the construction and repair of international vessels.

03.If my shipyard requires ship plates with LR or BV certification, can you supply them?

Sure. We can supply steel plates that are certified by multiple national classification societies, including LR, BV, DNV, ABS, NK, etc. Just indicate the required classification society when placing your order.

04.What is the minimum order quantity?

We support flexible order quantities. For ready-made products, an order of 5 tons is required; for custom rolled products, an order of 20 tons (one furnace batch) is usually necessary. New customers can place a trial order first.

05.Can you provide cutting and processing services?

OK. We offer pre-processing services such as CNC cutting, beveling, and drilling. We will process according to your drawings. Once the materials arrive at the factory, they can be assembled and welded directly, helping you shorten the shipbuilding cycle.
