■ "Tower Maintenance" Steel towers and steel pipe poles are protected against corrosion by hot-dip galvanizing and coatings. As long as they are protected, there is no reduction in cross-sectional area. However, the galvanizing and coatings will inevitably deteriorate over time. The lifespan of the tower greatly depends on when and how repairs are made. Our company's "Tower Maintenance" assists customers in economically managing the maintenance of their towers, from on-site inspections to repairs.
