Certificates 
All of our products have passed the laboratory tests and have the CE marking, which is something that very few manufacturers and companies in Bulgaria can boast of. This means that our products, whether it be garage doors, security shutters, or wooden window frames, meet the European requirements and standard.

For over 25 years we have been working hard to offer you seamless services and products and at the same time a fair market price. Our pricing is competitive without compromising on quality, so we can offer the best prices on the market.

The evolution of GSG
When we established stable and fixed positions on the Bulgarian market, our team decided to work in other European countries as well. The fruit of our efforts is the founding of our company GDD Fenster Handels GmbH in Austria.
