Here is one of the best stainless steel fabricators I have ever found (anywhere), and he is in Villa Consuelo. They can make anything, with or without your plans, or just a photo of what you want. I know that he makes a lot of the stainless steel restaurant grills/kitchens. They also do freezers, cold rooms, etc. Something which I liked is that Danilo delivered a quality finished product, on-time and at the prices (which I considered very reasonable) agreed to in the beginning (which was unusual with my suppliers here).
Hojalateria Industrial, Calle La Guardia No. 167, Villa Consuelo, Santo Domingo. Tele; 536-7457 and the owner is Danilo Eusebio Rojas. If you go, you can tell him that Carlos from San Isidro recommended him.
It was better for me to go there in person for a new job/quotation, but I never had any problems with telephone follow-up. Villa Consuelo is a place best visited in the daytime, jajaja.
