Sinalisa Segurança Viária Ltda Sinalisa's history began about four decades ago when the company was founded by the Ypiranga S/A group in 1971 in Rio de Janeiro. In 1982, it was acquired by the ERITRAM group and its headquarters were transferred to the capital of São Paulo. In November 2000, it moved to its current address in the Mooca neighborhood. A pioneer in the Brazilian road marking market, Sinalisa is a forerunner in lane marking painting with solvent-based acrylic paints, water-emulsified acrylic paints, high-thickness emulsified acrylic paints, conventional and high-relief thermoplastics, smooth, structured and embossed two-component methyl methacrylates.

Its scope of work is to prioritize services that aim to improve the safety of road users, through quality and good production performance.
