I'm looking to source corrugated plastic sheets, specifically in black, with dimensions of 4x8 feet and a thickness of around 4mm. If there's an option available for slightly thicker sheets, that would be acceptable as well. I'd like to place an order for 50 sheets or more, depending on availability and pricing. Delivery needs to be arranged to Sacramento, CA, specifically to the zip code 95814. Please provide your pricing, lead times, and any relevant details about shipping options. Looking forward to your prompt response!
