SERTSEM as a result of an alliance with SONTRAFIC, designs and manufactures traffic signals and high-quality accessories, injected in polycarbonate. We are market leaders due to our long experience in the sector, excellent quality, high performance and excellent client attention service.

Our attractive designs, combined with high-quality lighting (LED/incandescent) make our traffic signal heads an appreciated product, tried and tested in diverse climates.


Our ST range is the most popular of our traffic signal heads. Made of injected polycarbonate (UV-STABILIZED POLYCARBONATE), it is resistant to mechanical stress, adverse weather and sunlight, being our most robust and flexible range.


In addition to the technical characteristics of the ST model, this model, specifically designed for LED technology, slim and oval shaped, is transforming national and international urban landscapes, providing elegance and modernity wherever installed.
