The hauling of Frac sand is a big part of our business here at WTS Logistics. To be ahead of our competitors and make this type of haulage easy for our drivers, we rely on sand haul chassis. We have chosen those chassis that can meet our high standards. They must be able to withstand the continuous use we put them through for the transportation of frac sand and more than meet the DOT requirements. They have to provide a smooth run for our drivers and ease in delivery. At the same time, they have to retain their newness and durability. The Sand Haul Cassis collection within our fleet can do this and more.
