Key Features of Our Ship Plates

High tensile strength

Supplied to meet stringent international ship classification standards (ABS, BV, CCS, etc.), ensuring guaranteed tensile/yield strength and impact toughness for hull integrity.

Corrosion resistance

Available in grades specifically designed for seawater corrosion resistance. We can also supply pre-treated plates (e.g., primed) as per your construction workflow.

Good weldability

Excellent weldability with low carbon equivalent (C.E.), facilitating efficient shipyard fabrication and reducing cracking risks.

Processing Service

IBC Group provides more than just shipbuilding plates – we deliver project-ready steel solutions. Our in-house processing services transform raw plates into precise, pre-fabricated components, saving you time and ensuring quality from our factory to your fabrication line.

Start Customization

CNC Precision Cutting

We operate advanced CNC cutting machines (plasma & oxy-fuel) to cut plates to your exact dimensions or from provided CAD drawings. This ensures millimeter-perfect accuracy for complex shapes, eliminates manual cutting errors.

Shot Blasting & Priming

Our facilities can perform commercial-grade shot blasting to achieve a clean, anchor-profile surface (Sa 2.5 standard), followed by the application of high-performance shop primers. This delivers ready-to-use plates with superior paint adhesion and immediate corrosion protection.

Plate Leveling & Flattening

For plates requiring perfect flatness, we offer professional leveling services. This is critical for CNC cutting accuracy and ensuring assembly quality.

Customized Packaging

Plates or cut parts are securely bundled with protective edge guards and waterproof wrapping. We tailor the packaging method (wooden crate, steel frame) to your specific transportation and handling requirements, ensuring damage-free delivery to your port or site.
