WHY SHOULD YOU CHOOSE M.M.?

8 The FRP or GRP is commonly known as Fiberglass Reinforced Polymers. It is a material consisting of a matrix of thermosetting polyester resins reinforced in continuous glass fibers. These two components lend different properties to the material: the glass fibers give high mechanical resistance and represent the structural part, while the polyester resins tie together the glass fibers enabling stress distribution and high corrosion resistance. These properties allow their use in numerous applications. M.M. s gratings are manufactured according to our own unique RTM (Resin Transfer Molding) technology, based on the polymerization of the gratings in sealed molds, which guarantees a more homogeneous resin fitting and a minimal environmental impact. The handicraft works have been replaced by specially designed advanced robotic systems. FRP AND ITS TECHNOLOGY

9 THE ADVANTAGES OF OUR FRP LIGHT WEIGHT AND RESISTANT STRUCTURES EASY INSTALLATION MAINTENANCE FREE VERSATILE USE EXCELLENT MECHANICAL RESISTANCE/WEIGHT RATIO In the FRP products, the glass fibers confer a high mechanical strength and if compared to steel s weight it turns out to be more resistant. HIGH DIELECTRIC PROPERTIES FRP is non-conductive. GOOD FIRE REACTION M.M. products can be manufactured in a self-extinguishing version. RESISTANCE TO CHEMICAL AGENTS The resins used preserve the products characteristics - even if in permanent contact with most chemical compounds. RESISTANCE TO TEMPERATURE LEAPS AND HUMIDITY No residual defects have appeared after several exposure cycles of heat, cold and humidity. UV RESISTANCE No residual defects have appeared following the accelerated ageing test carried out with UV lamps. SEAWATER RESISTANCE The isophtalic resins that we use suffer no variation of their chemical and mechanical properties after 10 years immersed in seawater at a temperature of 50 C. RESISTANCE TO LOW TEMPERATURES The resins employed by M.M. can resist temperatures as low as -30 C. NO SOFTENING TO MEDIUM/HIGH TEMPERATURES The resins are thermosetting and therefore do not soften if exposed to medium-high temperatures. MINIMAL THERMAL EXPANSION FRP s low thermal expansion assists installation. DOES NOT RELEASE HAZARDOUS SUBSTANCES M.M. products do not release hazardous substances and our ACS certified version could be used in direct contact with drinking water. LIGHTWEIGHT Their specific weight of approximately 1,4 Kg/dm 3 make them be easy to handle and they do not put excessive burden on support structures.
