ROPES, CABLES, LINERS AND CASINGS
Specialists since 1943
Ropes and cables
The simplest cables are the strands, made up of several wires helically wound with one or more layers. The strands are the basis for making complex ropes. Ropes and strands can be swaged to offer greater mechanical and wear resistance and ensure greater smoothness inside the casings.
Flat wire cables are ropes wound with a flat wire, typically in stainless steel. The ropes, built with the most varied constructions, have different stiffnesses, resistance to fatigue and wear. The flat wire coating gives resistance to corrosion and abrasion, smoothness in the casings and tighter tolerances.
In.Tra.Flex produces a wide range of plastic liners. The choice of resin is based on the temperatures of use and the coefficient of friction. The resins used are HDPE, POM, PAs and PBT. New technopolymers with higher thermal resistance and low coefficient of friction are being developed to meet the various needs.
The firm, on the market for over 75 years, specializes in the production of wire ropes, flat-wire cables, helically wound cables, coated cables, liners and casings.
Founded in 1943 by Mario Spreafico with the name “Ditta Mario Spreafico”, it began its business as a spring manufacturer, specialized in spiral springs, and wire ropes retailer.
The production of ropes began two years after and soon became the main production.
