Recycled-Plastic-Composite Egypt Import and Export Companies

Hello, I am looking for WPC with these exact specifications and I need a very large quantity for a client. Total width: 19.5cm, 3 strips, each strip is 5 cm wide with internal structural support,and the the space between the strip and the base is 2.5cm. The space between the strips is 1cm. The thickness of the back part(or base) is 5mm. This is all illustrated in the drawing for further clarification. We need these as soon as possible. I am located in Cairo, Egypt, but these will be shipped to another country from the country of origin. Please let me know if these specifications are available, how fast they can be delivered, and of course, the cost.
