Profile: Trinity Marine Products, Inc. is a manufacturer of structural fiberglass reinforced plastic. Our products include track collector pan systems and environmental cover systems. We deliver barge covers and rail car covers. Our SynTechnics Environmental Cover Systems efficiently and economically capture odors and vapors created by substances contained in tanks or reservoirs. As they are made of fiberglass reinforced plastic (FRP), they provide maximum strength at minimum weight, are aesthetically pleasing, meet demanding environmental requirements and are resistant to corrosion. These FRP covers also minimize moisture collection points by eliminating excess flanges, fasteners and weldments.
