The National Association of Trailer Manufactures (NATM) addresses corrosion problems caused by de-icing chemicals sprayed on roadways.

March 3, 2010 - Reno Nevada

This presentation will focus on corrosive reactions caused by de-icing agents. Over the past 10 years, there has been a significant increase in corrosion, especially on over-the-road products and architectural coatings near roadways. There has been speculation on the composition and quality of the steel; however, the focus is now shifting to what is actually corroding the steel.

How this issue progresses will affect the process used in the trailer manufacturing industry in dealing with the ongoing corrosion issue we face. It was made clear the corrosion problems we face are directly caused by and or affected by the winter-time use of our products on the interstate roadways due to the chemicals the states have approved for de-icing. We will update on what the individual manufacturers will come up with to battle the ever changing environments our products must endure. A few items of concern are brake linings, electrical wiring, metal surfaces, including aluminum (painted or not), and rubber products. There are a number of options available to the industry which will be dictated in part by the market we serve. Here are the three culprits being used along with salt: Sodium Chloride, Calcium Chloride, and Magnesium Chloride. We suggest that trailer users wash their trailers often with soap and water, check their wiring at least once a year, and touch up any chips or rusted areas on steel frame parts. This maintenance will add years to the life of your trailer.
