Among trailer manufacturers, there is an ongoing effort to address costly corrosion and moisture intrusion. At Great Dane, approaches to combat corrosion include replacing corrosive metal with non-corrosive composite materials and applying coating systems on the metal components, according to Chris Lee, vice president of engineering. “Great Dane’s EnduroGuard rear frame uses stainless and galvaneal carbon steel to fight corrosion,” Lee explains. “Our CorroGuard thermoplastic coating used over carbon steel also enhances corrosion resistance. Today, we are also researching other coating systems such as zinc-rich epoxy primers and one-part waterborne coatings, for improved corrosion resistance.” To address moisture intrusion during outgassing throughout the life of refrigerated trailers, Great Dane developed a liner material with a non-permeable barrier called ThermoGuard. The glass‐reinforced, thermoplastic liner, as part of its composite construction, features a metal barrier layer that effectively seals the trailer’s insulation. Jong Seog Lee, vice president of research and development at Hyundai Translead, says that hot dip galvanization on all steel components and other criti...
