We set out as a workshop hammering metal 50 years ago... We grew, as the housing, business and ship building sectors grew and laid the foundations for today. We are continuing to grow with our General Head Office extending over an indoors area of about 15 thousand square meters in Sultangazi, Istanbul, our production facilities and our new facility investment extending over an area of 30 thousand square meters today.

We are enjoying the pride of being an example in the sector with qualified personnel of 325 people consisting of engineers (10%) and technicians (12%). Because we know very well that quality and success are closely related to personnel structure and have a high opinion of this issue. We constantly improve our personnel quality through in-house training seminars. We are also preferred by our customers for our quality, services and delivery times. We provide our customers with the highest level of services and logistic support under all circumstances with 65 elite dealerships all over Turkey.
