Welcome to Wuxi Yansheng Technology Co., Ltd. – a professional manufacturer of marine-grade aluminum plates established in 2017, with a factory spanning 1,000–3,000 square meters and an annual export value exceeding US$50 million. We specialize in supplying high-quality Marine Grade 6061, 6082, 6063 T6/T651 Aluminum Plates designed specifically for boat building and repair. Our products are trusted by clients across North America, South America, Europe, Southeast Asia, Africa, and Oceania, thanks to our rigorous quality control and adherence to international standards. Whether you need robust structural plates for new ship construction or durable repair panels for maintenance, our aluminum plates offer exceptional corrosion resistance, weldability, and strength-to-weight ratio.
Our manufacturing process combines advanced rolling technology with strict inspection protocols. Each plate is tested for dimensional accuracy, mechanical properties, and surface finish. We understand that marine environments demand materials that withstand saltwater, UV radiation, and mechanical stress. That is why we offer a range of tempers (T6 and T651) to match your specific requirements – from high-strength applications to improved machinability. All our plates are available in customizable thicknesses, widths, and lengths to fit your project needs.

Frequently Asked Questions (FAQ)
What is the difference between T6 and T651 temper?
Both tempers offer similar strength, but T651 undergoes stress relief to reduce internal stresses, providing better dimensional stability during machining. T6 is more common for general structural applications.How do I choose between 6061, 6082, and 6063 for my boat?
6061 is a versatile all-rounder for hulls and frames. 6082 offers higher strength for heavy-duty structural parts. 6063 is often used for extrusions and decorative elements due to its excellent surface finish. For repair, matching the existing alloy is recommended.Can you cut the plates to specific sizes?
Yes, we offer custom cutting services. You can specify exact dimensions, and we will cut the plates using precision shearing or sawing to meet your requirements.What is the typical lead time for an order?
Lead time depends on quantity and sizes. For standard sizes, it is usually 7–15 days after deposit. Custom orders may take 15–25 days. We expedite urgent requests upon request.Do you provide any surface treatment, like anodizing or painting?
Yes, we offer anodizing, brushing, and painting options. Please specify your requirements, and we can recommend the best finish for your marine application.Are these plates suitable for underwater use?
Yes, 6061 and 6082 are commonly used for underwater components like rudders and propellers. However, we recommend proper anti-fouling coating for long-term immersion.How do you ensure the quality of your plates?
We conduct chemical composition analysis, mechanical testing, and dimensional inspection for each batch. Certificates of compliance are available. We also welcome third-party inspections.What is the minimum order quantity (MOQ)?
Our MOQ is typically 1 ton for standard sizes. For custom or small orders, please contact us to discuss possibilities.
