I would like to thank you and your colleagues on behalf of my company for your valuable suggestions and support for successful installation of the glass at our site which had so many obstacles and lacunas. It is highly appreciable the way you suggested and installed such a high window for ventilation. The hardware used was really very good and functioning well. We are especially pleased at how many times you revised the concepts & drawing and respond to our alterations. We shall be recommending you to others and look forward to do more business with you in future.
