We're currently working on an innovative project in Pakistan focused on model farming, where we're implementing an advanced drainage system to manage underground water levels effectively. To support this initiative, we are looking for a reliable supplier who can provide us with specific types of perforated corrugated HDPE pipes in two different sizes. Our estimated requirement is around 12,000 meters, and we're eager to know if your factory can meet this demand. If you can assist us in sourcing these materials, please share your product specifications, pricing, and lead times. Looking forward to your prompt response so we can move forward with our project!
