Gramma was founded in 1972 in Thessaloniki, with initial activities in the manufacture of illuminated signs and the production of 3D acrylic letters. Over the years, our specialization in the processing of acrylic as a material for the construction of three-dimensional letters of inscriptions, has led us to verticalize their production and offer complete solutions in productions of both small and large scale. With the introduction in our company of automated CNC mechanical assemblies, our possibilities increased, both in scope and volume, making us now the largest manufacturer of acrylic letters in Greece. Collaborations with foreign companies such as PERSPEX, provide us with high quality and customized raw materials resulting in the expansion of manufacturing possibilities. We are constantly investing in research so that we can always offer our customers the best quality and have solutions for any demanding production.
