Stainless Steel – Used for specific corrosion-prone areas.
Aluminum Alloys – Lightweight for high-speed vessels.
How to Choose Thickness for Hull Plates?
Based on ship type and classification rules.
Small boats: 6-12mm, large ships: 15-50mm.
Higher thickness in critical areas like the keel and bottom.
Follow standards like ABS, DNV, or BV for specific ship designs.
What is the Difference Between AH36 and DH36 Steel?
Both are high-strength shipbuilding steels with a yield strength of 355 MPa.
AH36: Used in normal temperature conditions.
DH36: Has better toughness and is used in low-temperature environments.
How to choose the right grade of steel plate?
Selecting the grade depends on your ship’s size, operating conditions, and structural requirements. Common grades include AH32, AH36, and EH36. Our technical team can guide you based on your project needs.
Can shipbuilding steel plates be welded?
Yes, all our steel plates are optimized for welding processes and meet international standards for shipbuilding welding quality.
