The line of high chemical resistance gratings by M.M. was designed to meet the special requirements of primary and secondary chemical industries. This line is characterized by the use of pure, additive-free, isophthalic and vinylester resins as well as the use of a higher amount of resin compared to standard gratings in order to ensure total coverage of fibreglass. Isophthalic resins ensure maximum resistance to aggressive chemicals. Vinylester resins feature excellent mechanical properties at high temperatures. The M.M. high chemical resistance products are designed to resist to most acids and bases. They perfectly suit applications in chemically aggressive environments as well as special applications for equipment and machinery; they can be finally used for support structures, such as walking surfaces, gangways, ladders (inclined and vertical) and enclosures. In order to guarantee maximum safety, M.M. can supply products with excellent flame resistance in compliance with EN13501, ASTM E84, ASTM D635, DIN 4102, NFP 92-507 standards. Conductive and antistatic/dissipative gratings are also available; they are especially designed for ATEX areas. M.M. gratings are manufactured according to the DIN 25437-3 standard and can be supplied in a slip resistant version according to the DIN 51130 standard. Elevated walking surfaces are constructed according to the most stringent EU standards. To guarantee operators’ safety, M.M. also supplies FRP parapets. All M.M. products are manufactured according to UNI EN ISO 14122 – 1,2,3,4, standards and Legislative Decree 81/2008 on safety in the workplace.
