- Overview
- Recommended Products
- Multi-Society Certified: Single plates can carry dual or multiple classification society endorsements (e.g., ABS+CCS+BV), streamlining documentation for international shipyard projects.
- High Strength-to-Weight Ratio: Minimum yield strength of 355 MPa allows thinner plate sections, reducing hull weight and increasing cargo capacity.
- Excellent Toughness: Guaranteed Charpy impact performance at 0°C ensures structural integrity in standard marine operating conditions.
- Superior Weldability: Low carbon equivalent and controlled chemistry minimize preheat requirements and reduce the risk of cold cracking during shipyard fabrication.
- Flexible Delivery Conditions: Available as hot rolled (AR), normalized (N), or thermo-mechanically control processed (TMCP) to meet specific design and schedule requirements.
- Ready-for-Fabrication Surfaces: Optional shot blasting to SA 2.5 and shop primer coating reduce surface preparation time and protect plates during storage.
- Commercial vessel hulls, decks, and superstructures (bulk carriers, container ships, tankers)
- Offshore platform decks, jacket structures, and module supports
- Ship bulkheads, tank boundaries, and engine room foundations
- Port machinery, crane barge structures, and floating dock components
- Naval and coast guard vessel construction and repair
- River-sea intermodal vessel hull plating
Product Overview
We supply AH36 hot rolled shipbuilding steel plates fully certified by major international classification societies: ABS (American Bureau of Shipping), CCS (China Classification Society), LR (Lloyd's Register), GL (Germanischer Lloyd), RINA (Registro Italiano Navale), and BV (Bureau Veritas). AH36 is a high-strength structural steel grade engineered specifically for the construction of ship hulls, offshore platforms, and marine engineering structures. Produced in hot rolled condition, these plates deliver the high yield strength, excellent toughness, and superior weldability required to withstand the harsh demands of ocean-going service.

FAQ
Q: What does AH36 mean in shipbuilding steel?
A: AH36 is a high-strength shipbuilding steel grade. "A" indicates general strength compliance, "H" stands for high strength, and "36" refers to the minimum yield strength of approximately 355 MPa. The "A" also signifies that impact testing is conducted at 0°C.
Q: What is the difference between AH36, DH36, EH36, and FH36?
A: These grades share the same minimum yield strength (355 MPa) but differ in impact test temperature. AH36 is tested at 0°C, DH36 at -20°C, EH36 at -40°C, and FH36 at -60°C. Select the grade based on your vessel's operating climate and structural criticality.
Q: What is your minimum order quantity (MOQ) and typical lead time?
A: We accept orders from one metric ton or even single plates for urgent ship repair. Standard lead time is 15–30 days for stocked thicknesses. Non-stock sizes, large tonnage orders, or special processing (TMCP, UT, priming) may require 30–45 days. Break-bulk and container shipments are both available.
Q: What is Z-direction steel, and do I need it?
A: Z-direction steel (Z15, Z25, Z35) is specified when plates are subjected to high through-thickness tensile stresses at welded joints, such as cruciform connections, bracket toes, and heavy seam welds. The Z-grade indicates guaranteed reduction of area in the through-thickness direction, preventing lamellar tearing. We supply Z-grade AH36 upon request.
