STEEL PLATES PRODUCT OVERVIEW
High-integrity metallurgical plate solutions engineered for the fabrication of critical pressure equipment, heavy offshore jacket structures, and mega-scale industrial infrastructure.
- PRODUCT PORTFOLIO & STRATEGIC APPLICATIONS
Boiler & Pressure Vessel Steel Plates
- Application: Shell and head fabrication of high-pressure vessels, boilers, and heat exchangers.
- Performance: Stable yield strength and creep resistance under long-term high temperature and pressure conditions.
Structural Offshore & Marine Plates
- Application: Deepwater platforms, jacket legs, and offshore structural nodes.
- Performance: High fracture toughness and excellent through-thickness ductility (Z-quality) to prevent lamellar tearing under wave and dynamic loads.
Stainless & Heat-Resistant Alloy Plates
- Application: Chemical reactors, storage tanks, and distillation columns.
- Performance: Resistance to aggressive chemical corrosion, oxidation, and sour gas environments.
Metallurgically Clad Plates
- Application: Cost-optimized solution combining structural strength and corrosion resistance.
- Performance: Carbon steel base bonded with corrosion-resistant alloy cladding (Stainless, Duplex, or Nickel Alloy).

- MATERIAL REINFORCEMENT & TESTING PROTOCOLS
100% Ultrasonic Testing (UT) Verification
- All plates undergo full-surface ultrasonic testing in accordance with ASTM A435 / ASTM A578 to detect laminations, slag inclusions, and internal defects.
Severe Service Mechanical Testing
- Compliance with HIC (Hydrogen-Induced Cracking) and SSC (Sulfide Stress Cracking) requirements for sour service applications.
- Mechanical validation includes through-thickness (Z-direction) tensile testing and Charpy V-notch impact testing at sub-zero temperatures.
Premier Tier-One AVL Sourcing Network
- Materials sourced from globally recognized steel mills including POSCO, JFE, Nippon Steel, and Dillinger.
- Supplied with EN 10204 3.1 / 3.2 certification and verified by third-party inspection agencies such as Lloyd’s Register, DNV, and Bureau Veritas.
