After getting the quotation for 4 pairs of folding doors, we still chose WANJIA™. The price, workmanship and service all meet my requirements. Will come back to them when I'm ready to replace other windows and doors.

WANJIA™ is a very trustworthy door and window manufacturer. From quotation to production packaging, to installation instructions and more. I customized sliding windows and folding doors, and there are shutters between the glass and the glass. My wife and I are very satisfied, and I am very happy to cooperate with WANJIA™!
