Shipyards, maintenance and marine applications
We work with shipyards and manufacturers of boats, platforms and marine equipment, where components are permanently exposed to humidity, salt water, waves and corrosion. Structures, shafts, propellers, bushings and hardware require stainless steels, coppers, bronzes and steels with high resistance to the marine environment, to ensure durability, safety and low maintenance over time. At NAT MAC we supply these materials in the suitable grades and forms, along with cut-to-size services and specialized technical advice. We help select the alloy that best resists corrosion and real operating conditions at sea, so every component delivers the service life and reliability the marine industry demands.
