Get more profit by working with WANJIA


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.

Berton Camp 12/26/2021

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™!

I highly recommend Wanjia windows. We used them for our house in Canada and they were excellent. We are now working with them to replace the windows in our house in the Philippines. Excellent customer service and sales staff. The quality of the product is top notch.

3. Glass type, thickness (single/double interlayer or others) and color (tinted/reflective/Low-E or others, with or without hydrogen)
