MATERIAL MATERIAL MATERIAL !

Strong, shock and impact resistant, dimensionally stable

Josam's Pro-Plus range of new generation trench drains utilizes the benefits of space-age material. Pro-Plus 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.

Extraordinarily robust and yet surprisingly light these diverse properties highlight the advantages of SMC/GRP over other trench drain materials. The material has revolutionized many industrial products and has become indispensable in today's world. Its applications are wide and varied: rotor blades for helicopters, bodywork for automobiles, 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.

SMC is a tried and tested GRP material and is a compelling choice because of its extremely high strength and dimensional stability. For example, SMC/GRP is more than 1.5 times stronger than polymer concrete. In addition, SMC/GRP?s thermal expansion on average is 40% less than that of polymer concrete. These SMC/GRP material characteristics result in extreme rigidity and only minimal longitudinal expansion, even for wide temperature fluctuations. In contrast to thermoplastic polymers, SMC/GRP cannot be reshaped and remains dimensionally stable once heated compression hardens the material into the final product.

This product 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 poly- ethylene. SMC/GRP is an innovative material and is clearly superior to all other trench channel materials.
