I'm looking for a durable metal plate that is non-corrosive, with dimensions of approximately 2.4 meters by 1.550 meters. This plate is intended for a project where durability and resistance to environmental factors are critical. It would be great to understand the available grades of metal, as well as any protective coatings or treatments that can enhance its lifespan. Additionally, I'd appreciate information on pricing, lead times, and minimum order quantities. If there are any specific certifications or quality standards that the product meets, please share that as well. Looking forward to your detailed response and any recommendations you might have!
