The high-strength steel side panel option is currently only available for the DX-100, which comes as an alternative to the standard .040-inch aluminum side skin. This option provides a means of countering fluctuations in the price of aluminum.
Using the same durable exterior side skin material found on plate trailers, this new option features .016-inch high tensile 80,000 psi, pre-painted white galvanized steel panels that cover the full length of the trailer, including the front wall.
Additionally, a new side wall system will be made available for both the optional DX-100 and the standard DX-101. It features 18-gauge, 100,000 psi galvanized steel side wall posts in the bay area, and this offers significant weight savings for increased payload capacity.
