In 1997. Marko implemented the concept of marketing the Roll-on System through accredited distributors denominated DEALERS. Five years later, the network was already celebrating the delivery of 500 works completed.
With the success of the model, the Roll-on System began to be sold exclusively by the Dealers, who receive full training and support for the development of projects, marketing and assembly of the product.
Annually the distributors are recertified according to their performance, in this way upholding the standard of quality required by Marko.
