Fiberglass Reinforced PolymersGratings and structures
M.M. s.r.l. was established in 1977 and was the first European producer of FRP gratings (Fiberglass Reinforced Polymers). M.M. has been growing steadily over the years, both in size (at the moment the company is operating in two plants on an area of 13,000 m²), as well as in its production range.
Today M.M. offers gratings, profiles and structures in FRP (parapets, gangways, ladders, fences, gates) and a wide range of accessories.
Customer satisfaction is our priority at every step of our business process, from design to production, from the proposal to post-sale service.
We design and supply high quality standard customized solutions according to clients’ specific needs, to guarantee safety for the users of our products.

We personally test the integrity and the compliance of our products using machines and tools specifically made for the task, drawing upon the expert advice of external laboratories and institutes.
WHY SHOULD YOU CHOOSE
M.M.?
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The handicraft works have been replaced by specially designed advanced robotic systems.
FRPAND ITS
TECHNOLOGY
EXCELLENT MECHANICAL RESISTANCE/WEIGHT RATIOIn 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 PROPERTIESFRP is non-conductive.
GOOD FIRE REACTIONM.M. products can be manufactured in a self-extinguishing version.
RESISTANCE TO CHEMICAL AGENTSThe resins used preserve the products’ characteristics - even if in permanent contact with most chemical compounds.
RESISTANCE TO TEMPERATURE LEAPS AND HUMIDITYNo residual defects have appeared after several exposure cycles of heat, cold and humidity.
UV RESISTANCENo residual defects have appeared following the accelerated ageing test carried out with UV lamps.
SEAWATER RESISTANCEThe 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 TEMPERATURESThe resins employed by M.M. can resist temperatures as low as -30°C.
NO SOFTENING TO MEDIUM/HIGH TEMPERATURESThe resins are thermosetting and therefore do not soften if exposed to medium-high temperatures.
MINIMAL THERMAL EXPANSIONFRP’s low thermal expansion assists installation.
DOES NOT RELEASE HAZARDOUS SUBSTANCESM.M. products do not release hazardous substances and our ACS certified version could be used in direct contact with drinking water.
LIGHTWEIGHTTheir specific weight of approximately 1,4 Kg/dm3 make them be easy to handle and they do not put excessive burden on support structures.

BEFORE TESTING
FRP GRATING STANDARD
GALVANIZED STEEL GRATING
Have a look at these tests done with the collaboration of the
Università Tor Vergata in Rome.
The tests were carried out by immersing the samples in the
specified substances for the given time. The pictures clearly show that there were no significant
modifications to the FRP grating.

M.M. FRP gratings are designed with a high safety factor and are manufactured according to the DIN 24537-3 standard.
Our gratings are manufactured in a wide range of sizes in order to guarantee an immediate solution to various design problems and are produced in monolithic panels that are easy and fast to install.
They can be supplied with an anti-skid certified surface according to the DIN 51130 standard. On request, they can be supplied in the self-extinguishing variation.
Further to the classic gratings, M.M. can supply products with specific technical characteristics for their use in particular locations that require distinctive features (particularly aggressive environments, potentially explosive areas, shipbuilding, outdoors and marinas).
FRP GRATINGS
M.M. gratings can also be supplied in conductive or non-static dissipative versions to avoid developing electro-static charges.
Micromesh, “high heel proof” gratings, are available for pedestrian areas and raised floors; square mesh gratings are specific for heavy load floors and are easy to install; rectangular mesh gratings are ideal for fences; covered gratings are distinguished by their lightweight and the high mechanical properties.
Our high chemical resistance gratings, manufactured with isophtalic or vinylester resins, additive free, are appropriate for use in chemically aggressive environments. The structural shape is designed in order to achieve a greater glass fiber covering.
M.M. Compodeck is the only composite grating classified L1 according to U.S. Coast Guard regulations. It’s an innovative product that adds fire resistance to the composite’s usual properties – a characteristic that other composites can’t boast. This particular grating has been designed for the shipbuilding sector and complies with the high technical and safety standards required by the U.S. Coast Guard.
Thanks to the Q-paint finishing, the Marinadeck is an original and innovative grating suitable for foot traffic, including bare feet (anti-skid according to DIN 51097). It’s recommended for outdoor areas, marinas and seafront.

STRUCTURES FOR ACCESS TO
MACHINERY
STAIRWAYS, GANGWAYS AND PLATFORMS
The access to machinery or to a part of a plant may require a specific solution: our structures are the answer.
M.M.’s technical department takes over the management of the customer’s enquiries with on-site inspections and works out the best solution respecting the safety standards and the clients’ needs.
A 3D modelling system, advanced calculation softwares are used for the structural dimensioning according to the Italian and International standards in force.
The construction drawings and the installation instructions complete the customer service, ensuring that M.M.’s structures are installed correctly and last for years.
LIGHTNESS: their light weight reduces the load on the weight-bearing structures and are easy to handle in construction yards. This reduces installation time and costs.
NO MAINTENANCE: the servicing costs will be considerably reduced.
SAFETY: our gratings guarantee an anti-skid floor according to the DIN 51130 standard.
DIELECTRIC PROPERTIES: grounding is not necessary.
ADVANTAGEOUS: in extremely harsh environments, they could replace S.S. with substantial money savings.
