Hemaokang Steel (Shandong) Co., Ltd. brings you a premium range of 304/316L stainless steel plates specifically engineered for marine exterior cladding. With a 10mm thickness, pickled surface, and 6000mm length, these plates deliver dependable corrosion resistance in saltwater and coastal environments. Our factory in Liaocheng, Shandong, combines integrated production and strict quality control to supply global clients with steel that performs — whether for ship hulls, offshore platforms, docks, or architectural facades.
Our stainless steel plates are manufactured to meet demanding marine standards. The pickled finish removes oxidation and scales, giving a clean and uniform surface that improves weldability and coating adhesion. The plates are cut accurately to 6000mm length and can be customized in width. We provide both 304 and 316L grades, allowing you to choose the optimal balance between cost and corrosion resistance for your specific application.
Key Features & Product Details
- Superior Corrosion Resistance – The 316L grade contains molybdenum, which enhances resistance to chlorides and seawater, making it ideal for exterior marine cladding.
- 10mm Thick Construction – Provides high structural strength and impact resistance, suitable for heavy-duty cladding and marine structures.
- Pickled Surface Finish – Removes impurities and scale, resulting in a smooth, clean surface that is ready for fabrication or painting.
- 6000mm Standard Length – Reduces the number of joints in cladding installation, improving aesthetics and reducing potential leak points.
- 304 & 316L Grades Available – 304 for general corrosion resistance; 316L for harsher marine and chemical environments.
- Customizable Width – Width options such as 1500mm, 2000mm, and 2500mm can be supplied based on project requirements.
- Excellent Weldability & Formability – Suitable for cutting, bending, welding, and forming processes during installation.
- Reliable Chemical Composition – Controlled alloying elements ensure consistent mechanical properties and long-term durability.

Why Choose Hemaokang Steel for Your Marine Projects?
We understand that marine environments are unforgiving. Salt spray, humidity, and temperature variations can quickly degrade inferior steel. Our stainless steel plates are produced with strict alloy control and surface treatment to provide reliable performance under these conditions. The pickled finish not only improves corrosion resistance but also gives a professional look for exterior applications.
With each plate measuring 6000mm in length and 10mm in thickness, you can cover large surface areas with fewer joints. This reduces installation time and lowers project costs. We also support custom cutting and processing services, including shearing, laser cutting, and edge preparation, to meet your exact design drawings.
The 316L option is particularly suited for marine exterior cladding where chloride stress corrosion cracking is a concern. Its low carbon content minimizes sensitization during welding, preserving corrosion resistance in the heat-affected zone. If you are working on coastal architectural facades, ship exteriors, or offshore platform cladding, this grade offers the reliability you need.
Packing & Delivery
- Packed with moisture-proof paper and steel straps, suitable for sea freight.
- Wooden pallets or wooden cases are available for smaller orders.
- Standard export packaging protects the pickled surface from scratches and seawater moisture.
- Shipped from Qingdao port, one of China's major ports, ensuring fast and reliable logistics.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between 304 and 316L for marine cladding?
A: 316L contains molybdenum, which provides significantly better corrosion resistance in chloride-rich marine environments. 304 is suitable for less aggressive coastal areas, while 316L is recommended for tidal zones, ship hulls, and offshore structures. -
Q: Is the 6000mm length exact?
A: Yes, the standard length is 6000mm. We also offer custom lengths based on your drawings, with tolerance typically per ASTM A480. -
Q: Can the width be customized?
A: Yes, width can be customized. Common widths are 1500mm, 2000mm, and 2500mm, but other dimensions are available upon request. -
Q: What does the pickled surface look like?
A: A pickled surface is clean, matte, and free of scale and oxide layers. It is slightly rougher than a 2B finish, which is ideal for painting or for applications requiring good adhesion. -
Q: Do you provide material test certificates?
A: Yes, mill test certificates and, if required, third-party inspection reports can be provided. Please specify your requirements when ordering. -
Q: How is the plate packed for export?
A: Plates are packed with protective film (optional), moisture-proof paper, and steel strapping. They can be secured on wooden pallets or in wooden crates for sea transportation. -
Q: What is the minimum order quantity?
A: MOQ is typically 1 ton, but we can be flexible for sample orders. Larger quantities receive better pricing. -
Q: Can you provide cutting or processing services?
A: Yes, we offer shearing, laser cutting, bending, and edge milling as optional processing services. Please contact us with your specifications.
