罗马尼亚采购需求：铝窗，铝幕墙，铝凉亭，铝栏杆，铝甲板栏杆，Westbury 铝栏杆

We are currently exploring options for high-quality aluminum and metal windows and doors for an upcoming project. Specifically, we're interested in foldable vertical windows with dimensions around 3000mm in length and 2800mm in height. We prefer a finish in RAL 7016 Anthracite Grey, and it's essential that these windows come with double insulated glass for optimal energy efficiency. Could you please provide me with a detailed quotation for this product, including any available customization options, lead times, and shipping costs to Romania? We are eager to review your offer and see how we can collaborate effectively. Thank you!
