To produce guide rails and accessories in accordance with and above the international standards or on specific customer standard is, for the Monteferro Group, a necessary but not sufficient condition for operating in the market. Guide rails should be supplied in such a way as to minimise the total cost of the installed guide. That is the reason why, besides developing and investing in its own process for the continuous optimisation and improvement of its products, the Monteferro Group has developed activities in collaboration with its customers in order to obtain best results both on quality and on cost, offerring not only a product but a global service to the elevator market.
