About Marine Industry

The marine industry, a vital global sector, includes shipbuilding, offshore platforms, and coastal infrastructure, projected at $300 billion by 2030 (Deloitte Marine Outlook).
It demands corrosion-resistant, high-strength steel for vessels and rigs. SHH STEEL, a leading stainless steel supplier and carbon steel exporter, offers FH36 ship plates and 316L stainless steel (ASTM A240) for durability.
From hulls to offshore structures, our steel withstands saltwater and extreme loads, adhering to ISO 9001 and DNVGL-OS-B101 standards.
We supply tailored plates to over 50 countries, ensuring safety and efficiency for marine projects.

Industry Pain Points

The marine industry faces severe challenges impacting safety and costs. Corrosion in seawater degrades steel by 20-30% (IMO 2025), costing $50 billion annually (LR Marine Report).
High maintenance from wear increases expenses by 40% (DNVGL 2025), with $10 billion spent yearly (Lloyd’s List).
Material strength issues cause 60% of structural failures (IACS 2025), losing $1.5 billion.
Compliance with ABS and IMO standards sees 30% rejection rates, delaying approvals 3-6 months (RINA 2025).
Fabrication of 150mm plates is complex, raising costs 25% due to labor shortages (Skanska Marine 2025)

Our Solutions

SHH STEEL addresses marine industry needs with advanced steel. For corrosion, 316L stainless (ASTM A240) resists 1,000+ hr ASTM G48, extending hull life 50%.

Strength is enhanced with FH36 plates (ASTM A131), offering 490-620 MPa, meeting DNVGL-OS-B101 with 95% approval.

Maintenance is reduced with clad plates (ASTM A264), cutting costs 40%. Fabrication of 150mm plates uses waterjet cutting (ISO 9013, ±0.2mm), saving 35% time.

Our low-carbon steel (20% emission cut, IEA) and 3-7 day Asia shipping ensure efficiency for marine projects
