Shri Navjoth Singh Khatra: Initially was not sure to go ahead with UPVC doors and UPVC windows. But, when S M Fabrications has explained us the advantages of this UPVC Material, we went ahead with it. Our guest house is now beautified with the perfectly fitted UPVC Doors and Windows of SM Fabrications. We are waiting for them to provide us the double lock which we have ordered it specially. Hope to get them soon!
