One of my customer want Waterproof_membrane which thickness is 1mic-1.5mic. The quantity would be very big, I promise if ur price is very good. We need the cheapest price. And we also have target price. So pls provide me your best price. The material is LDPE or TPO. Because I think these 2 materials are cheaper than others. If u have other material cheaper than these 2, also pls kindly suggest. The specification could be length-3000m*width-1.5m. I need the price by sqm. Ur prompt reply would be highly appreciated. BR
