We can supply all types shipbuilding steel plate in different sizes, thin thickness to thick heavy thickness, can cut to size, cut to length, different types sheet metal fabrication,ABS A.B.D AH32 DH32 AH36 DH36 ShipBuilding Steel Plate.
Common size on stock, Special sizes needs new production.Can cut to Size, cut to Shape.
We supply a comprehensive range of ABS-certified shipbuilding steel plates covering ordinary-strength grades A, B, D and higher-strength grades AH32, DH32, AH36, DH36. Manufactured in compliance with ABS Rules for Materials and Welding and harmonized with ASTM A131/A131M, these hot-rolled structural plates deliver exceptional toughness, weldability, and corrosion resistance for hull construction, offshore modules, and marine engineering projects.
All plates are produced via BOF/EAF + LF + VD smelting, controlled rolling (TMCP) or normalized (N) processing, and 100% ultrasonic testing (UT) to ensure compliance with class society requirements.

Key Product Features
Class Society Certified: Full ABS traceability with mill test certificates compliant with ABS Rules and IACS UR W11/W16.
Superior Low-Temperature Toughness: Grade D, DH32, and DH36 are impact-tested at –20 °C, ensuring safety in polar and cold-water routes.
Excellent Weldability: Low carbon and controlled carbon equivalent (CE) design minimize hardening in the heat-affected zone (HAZ), compatible with conventional arc welding and high-heat-input welding.
High Strength-to-Weight Ratio: AH32 and AH36 grades allow reduced plate thickness and lighter hull designs without compromising structural integrity.
Controlled Rolling & TMCP: Optimized grain structure for enhanced toughness and through-thickness properties.
Full Traceability: Each plate is stenciled with heat number, grade, dimensions, and ABS stamp; full chemical and mechanical test data are recorded in the MTC.
Typical Applications
Commercial cargo vessel hulls, decks, and bulkheads
