I am so happy to meet such a professional Chinese curtain wall supplier. What I encountered before was really not good. I always felt inefficient, the sample quality was not good, and the sense of communication and service was poor, but Hanlun changed my mind. From the initial communication and negotiation to quick quotation, high-quality sample delivery, as well as the follow-up of mass production and after-sales problem solving, I have always appreciated and agreed with this company.
