Josam’s PRO-PLUS® trench drain system is manufactured using glass-fiber reinforced polyester (GRP) pressed from sheet molding compound (SMC), which is a composite of polyester resin, mineral fillers and glass-fiber mats.
The material has revolutionized many industrial products and has become indispensable in today’s world. Its applications are wide and varied: from rotor blades for helicopters, bodywork for automobiles, to yachts and aircraft. In fact, glass-fiber reinforced polyester made from SMC is used wherever extreme conditions prevail and special degrees of durability and rigidity are called for, precisely as in JOSAM’s PRO-PLUS® drainage solutions.
PRO-PLUS® is lighter, stronger and expands and contracts in extreme temperature ranges less than polymer concrete. In addition, SMC/GRP has greater compressive, flexural and tensile strength and less thermal expansion properties than either polypropylene or high-density polyethylene. SMC/GRP is an innovative material and is clearly superior to all other trench channel materials.
Josam’s PRO-PLUS® Trench Drain System is available in various widths and depths and offer a wide range of grates which enables Josam to provide a solution to your application needs. Dedicated and knowledgeable customer service personnel are available to assist you in selecting the right engineered trench drain system for your project.
