Lode King Industries was founded in 1980 in Winkler, Manitoba and is a division of Triple E Canada Ltd. It began as a small manufacturing facility with a hopper bottom grain trailer being the only product. Lode King is now the largest highway transport trailer manufacturer in western Canada. The scope of product offerings has expanded as the years progressed to include aluminum and steel combination grain trailers and eventually a variety of flat deck trailers using both steel and aluminum materials.
