Parvan Toos Steel Complex
The shipbuilding and offshore construction industry is among the most demanding consumers of steel plate and steel sheet products worldwide. Marine structures are permanently exposed to humidity, cyclic loading, vibration, saltwater corrosion, and severe environmental conditions. For this reason, the quality and consistency of every hot rolled steel plate and hot rolled steel sheet used in ship structures directly affect safety, durability, and long-term operational performance.
At parvan, the development of industrial and structural flat steel products is aligned with the requirements of marine and offshore projects. As part of its strategic production and expansion plans, parvan steel has established the technical capability to supply carbon steel plate, carbon steel sheet, and heavy-duty structural steel plate for shipbuilding and marine structures.
The Importance of Steel Plate and Steel Sheet in Shipbuilding
In the construction of ship hulls, service vessels, barges, offshore platforms, and steel port structures, steel plate and steel sheet are the primary structural materials.
In such applications, a reliable hot rolled steel plate must simultaneously provide:
-
Adequate mechanical strength for high structural loads
-
Stable weldability in large and complex assemblies
-
Proper performance under cyclic stress and vibration
-
Uniform hot rolled steel plate thickness and consistent surface quality
These technical requirements are fundamental for modern shipbuilding projects that utilize heavy structural steel plate sections.
parvan steel’s Production Approach for Marine Applications
At parvan steel, flat products are manufactured through slab rolling technology, enabling the production of heavy hot rolled steel plate and hot rolled steel sheet suitable for structural and offshore projects.
Through controlled rolling parameters and process monitoring, the produced steel plate and steel sheet can be applied in large-scale marine structures.
In addition, the production strategy allows the supply of plates prepared for further heat treatment when required by project specifications, supporting customized mechanical performance for shipbuilding structures.
Product Scope and Dimensional Specifications for Shipbuilding Steel Plate
The current production range at parvan focuses on carbon steel plate and carbon steel sheet for heavy structural and marine use.
Product type: Carbon and structural steel plate and steel sheet
Manufacturing process: Hot rolling (Hot Rolled Plate)
Current production thickness range: 20 – 40 mm
Standard width: 1250 mm
Standard length: 6000 mm
Delivery form: Steel sheet
This range includes standard heavy plates such as the 20 mm hot rolled steel plate, widely used in ship hull sections, decks, and supporting marine structures.
ST37 Steel Plate and Steel Sheet for Marine Structures
Among widely used structural grades, ST37 steel plate and ST37 steel sheet are commonly applied in general ship structures and marine supporting components.
From a technical perspective:
-
ST37 chemical composition ensures suitable weldability and formability.
-
ST37 mechanical properties provide sufficient strength and ductility for structural and semi-structural marine applications.
-
When required, engineers may compare this grade with its international alternatives as ST37 equivalent steel for project documentation and cross-standard compliance.
Phase Two Development Program for Shipbuilding Steel Plate
In response to the increasing demand for lighter and thinner marine structural components, parvan steel has defined a second-phase development plan focused on expanding the product portfolio.
Planned thickness range: 8 – 15 mm
Annual production capacity: 150,000 tons
Main applications:
-
Shipbuilding
-
Offshore and coastal structures
-
Marine and port-related industries
This expansion enables the supply of thin and medium-thickness hot rolled steel sheet and steel plate suitable for modern ship structures and modular offshore systems.
Applications of parvan Steel Plate in Marine and Offshore Projects
The products supplied by parvan can be used in the fabrication of:
-
Hull structures of various ships and vessels
-
Barges and service vessels
-
Steel piers and offshore platforms
-
Structural components for marine industries
-
Port infrastructure and coastal support structures
These applications typically rely on high-quality structural steel plate and heavy carbon steel plate products.
Technical Advantages of parvan Steel Products for Shipbuilding
Key technical features of parvan steel products for marine use include:
-
Uniform plate thickness and consistent surface quality
-
Reliable weldability for large and complex structures
-
Dimensional stability of delivered steel sheet and steel plate
-
Availability for additional heat treatment when required
-

Steel Plate Weight, Thickness Control, and Project Planning
In shipbuilding projects, accurate material estimation is critical. Engineers commonly evaluate:
-
steel plate weight per square meter
-
A detailed steel plate weight chart for different thicknesses
-
Digital tools such as a steel plate weight calculator or a
steel plate weight calculator online
Precise control of hot rolled steel plate thickness directly supports reliable weight estimation, structural calculations, and logistics planning for large marine projects.
