The founder of our company, Ahmet AMAN, began his experience in the steel industry in 1988 and, after being involved in various stages of steel production for about 10 years, has been specializing in the manufacturing, servicing, and sales of steel doors since 1998. Having gained extensive experience with leading institutions in the country in this field, he recognized the challenges faced by the industry. In order to provide genuine service, he established SİMA KAPI SİSTEMLERİ SAN VE TİC LTD ŞTİ in 2013.

Our company quickly became one of the sought-after names in the sector due to the high quality of manufacturing and installation, emphasis on security, a diverse range of models, and timely deliveries. With special design doors, outdoor steel doors, and craftsmanship reminiscent of antique and hand-carved solid work, our company has become a prominent name in a short period. Our steel doors are preferred by leading construction companies in Turkey for both collective and individual significant residential and villa projects.

Moreover, our company has pioneered the production of specially designed steel doors with a 20-year guarantee for outdoor environments, a first in Turkey.
