Why Galvanization is Better than Painted A Frames:

  1. Most economical:Galvanized steel is often the least expensive initial choice. As other labor intensive coatings have risen in rates, galvanizing has maintained a consistent price-point. Moreover, it lasts longer and requires less maintenance, making it the most cost effective, long-term option.
  2. Maintenance-free: – Galvanizing provides maintenance-free corrosion protection, unlike other protective coatings. This mitigates long-term costs, hassles and disruptions to production.
  3. Longest lifespan: – Galvanized coatings on typical structural members have a life expectancy in excess of 100 years.
  4. Most durable: – A galvanized coating has a unique metallurgical structure, providing outstanding resistance to damage during transport, erection and service.
  5. Most reliable performance: – Galvanizing is carried out to ASTM A123 and standard, minimum coating thicknesses are applied. Coating life and performance are reliable and predictable as it’s performance is based on the known corrosion rate of zinc. Galvanized steel provides a thick, complete and easily inspected coating.
  6. Most protection: – Galvanizing protects every part of a structure, including recesses, sharp corners and inaccessible areas. Galvanized coatings also provide cathodic or sacrificial protection to small areas of steel that are exposed due to damage. Unlike other coating options, small damaged areas are automatically protected and don’t require touch-ups due to zinc’s sacrificial nature.
  7. Environmental Sustainability: – Zinc, like steel, is a natural substance that is recyclable.
