Mill certificates issued against the ordered grade and standard. Third-party inspection available on request.
What This Material Is For
Shipbuilding steel plate in AH32, AH36, AH40, DH32, DH36, DH40, EH32, EH36 and EH40 grades is available in thicknesses from 5 to 150mm, widths from 1500 to 3900mm, and lengths of 6000 or 12000mm, with customization possible. Buyers who would otherwise source hull plates, deck plates and structural sections from separate mills can consolidate the entire steel scope under one contract, one inspection and one shipment. The full range of grades covers the strength and toughness requirements for ship hulls, decks, bulkheads and superstructures across different service conditions.
Why Buyers Choose It
- Single-source procurement for multiple shipbuilding plate grades and dimensions, reducing coordination across mills
- Custom thickness, width and length available to match exact hull or structural panel requirements
- Grades AH32 through EH40 cover the full strength and toughness spectrum for modern ship construction
- One contract and one inspection for mixed-grade plate scope, avoiding multiple shipment dates
- Export-ready packaging and logistics support for global delivery to shipyards and fabricators
Where It Is Used
- Hull plating for offshore vessels and cargo ships using AH32, DH36 or EH36 grades
- Deck and superstructure plates in AH36 and EH40 for high-stress areas requiring impact resistance
- Bulkhead and frame sections in DH32 and EH32 where weldability and toughness are critical
- Ship repair and retrofit projects needing exact grade matches for existing hull sections
- Fabrication of modular ship sections where multiple plate grades are used in one assembly
Who It Is For
- Shipyard fabricators sourcing mixed-grade plate for a single vessel or hull package
- Marine engineering firms specifying AH32 to EH40 for different structural zones
- Ship repair yards replacing plates with exact grade and thickness matches
- EPC contractors managing integrated steel procurement for offshore platform or barge projects
- Steel processors who need plate in multiple grades and sizes for cutting and forming
Problems It Solves
- Splitting plate procurement across multiple mills due to grade or thickness limitations
- Delays caused by mismatched delivery dates when ordering hull, deck and structural plates separately
- Difficulty in finding EH32, EH36 or EH40 grades in custom thicknesses from a single supplier
- Inconsistent mill certificates and inspection records when sourcing from multiple vendors
- Lack of customization options for width and length that match panel layout designs
Technical Features
- Grades AH32, AH36, AH40, DH32, DH36, DH40, EH32, EH36, EH40 supplied to meet shipbuilding standards
- Thickness range from 5mm to 150mm, with custom thickness available on request
- Width range from 1500mm to 3900mm, with custom width possible
- Lengths of 6000mm and 12000mm standard, with custom length options available
- Full compliance with international shipbuilding codes and material specifications

Grades Standards And Size Range
Values below come from the published product data. Anything not listed is confirmed per enquiry.
| Grades | AH32, AH36, AH40, DH32, DH36, DH40, EH32, EH36, EH40 |
|---|---|
| Thickness | 5-150mm or customized |
| Width | 1500-3900mm or customized |
| Length | 6000, 12000mm or customized |
| Standard | Shipbuilding steel plate standards including Chinese GB, American ABS, British LR, German GL, French BV, Japanese NK, and Russian Rostekhnadzor |
Materials
- Carbon steel plate with controlled chemical composition for weldability and toughness
- High-strength low-alloy (HSLA) steel for grades DH32 and above, designed for structural load-bearing
- Fine-grain steel for EH32, EH36 and EH40 grades, providing improved impact resistance at low temperatures
- Steel with specified carbon equivalent (CEV) for weld zone integrity in thick sections
- Material suitable for submerged arc welding (SAW) and gas metal arc welding (GMAW) processes
Manufacturing Route
Quality Control
- Chemical composition and mechanical property testing against the ordered grade and standard
- In-house CNAS-certified laboratory performs routine testing including tensile, impact and hardness
- Third-party inspection available on request, bookable at order stage
- Mill certificates issued per purchase order, covering grade, standard, test results and batch number
- Non-destructive testing (NDT) available upon request for critical applications
Customisation Options
- Custom thickness, width and length available to match panel layout and fabrication needs
- Grade selection per plate item, so one order can mix AH32, DH36 and EH40
- OEM service accepted for marking, branding or special labeling
- Packaging tailored to shipping method (seaworthy, stackable, moisture-resistant) and destination port
How It Compares With The Alternatives
| Standard carbon plate (e.g. Q235B) | Carbon plate is cheaper but lacks the toughness and weldability required for shipbuilding; EH grades are essential for cold-weather service and high-stress zones |
|---|---|
| Structural steel plate (e.g. S355J2) | Structural plate is not certified for marine use; shipbuilding grades have stricter impact and weldability requirements |
| Low-alloy structural plate (e.g. S460N) | S460N is stronger but not designed for ship hulls; shipbuilding grades are optimized for fatigue, corrosion and welding in marine environments |
Buying Guide
- Start with the vessel type and structural zone (hull, deck, bulkhead) to select the appropriate grade
- Specify thickness, width and length early in the enquiry to confirm availability
- For cold-weather service, confirm whether EH32 or higher is required for impact resistance
- Include the applicable standard (e.g. ABS, GL, BV, NK) in the enquiry to ensure correct certification
- Request third-party inspection at order stage to align with yard or classification society schedules
