Our history

Our history

Since 1973 Sina Serrature has specialized in the production of locks for doors.

Sina Serrature is an Italian family-run business, founded by Mr. Roberto Sina, later joined by his wife Maria Laura Zatti. Since 2018 the business has continued thanks to 3 new partners (two of whom are grandsons of the founder), all with over 25 years of experience within the company. 50 years of experience and constant research towards the highest safety standards allow us today to proudly offer quality locks, certified and technologically always up to date with market demands.

For this reason Sina Serrature is appreciated both nationally and internationally: today we are present in more than 40 countries.
