The Revolution of Composite Material Poles
No longer simple inert supports made of easily perishable materials, but smart elements in the creation of aerial wired networks, to reach even the most inaccessible and hostile areas in an easy, economical and durable way, minimizing risks for operators or road safety. An effective revolution for telephone operators, who are increasingly adopting this solution.
Our commitment to the environment
S.I.L.T.I. Sud’s commitment to the environment and natural resources throughout the production cycle stems from the fiberglass pole, a recyclable support with the lowest possible impact. This commitment is ISO14001 certified and led in 2025 to the installation of a 250kW photovoltaic system.
