M.M. GRIGLIATI - WE SUPPORT YOUR NEEDS

FRP gratings are made of polyester or vinylester resin, fibreglass and inorganic halogen-free fillers that provide the self-extinguishing properties. They are supplied with anti-slip surfaces of varying levels, classified and certified according to the DIN 51130 standard (determination of the anti-slip properties). Gratings are certified as durable product whose mechanical performance is not affected by the cycles of hot/cold e humidity exposure in accordance with the UNI EN ISO 9142 standard; they have also passed the aging resistance test with cycles of UV exposure in accordance with the ASTM G154 standard; they are supplied with self-extinguishing properties in accordance with EN13501, ASTM E84, ASTM D635, DIN 4102, NFP 92-507 standards. They are tested and classified as excellent electrical insulators.

Profiles are obtained with the pultrusion technology which, by allowing to use a very high percentage of fibreglass, guarantees high mechanical performance. Standard profiles are made of isophthalic resin. On request they can be produced using other resins to meet specific customer needs. The standard colours are grey (RAL 7035) or yellow (RAL 1018). All profiles are finished with a polyester surface veil which, since impregnated with a large quantity of resin, seals the profile surface, ensuring the protection from UV rays and atmospheric agents and preventing the fibreglass from blooming. The high mechanical performance, lightness, ease of processing, resistance to chemical and atmospheric agents of the profiles, allow to create versatile and long lasting structures.

The handrail systems are made with pultruded profiles in isophthalic polyester resin and fibreglass. The handrail systems, supplied with vertical or horizontal fixing, are designed and manufactured according to UNI EN ISO 14122-3 standard and are available in standard or ergonomic versions. The ergonomic handrail differs from the standard handrail for its ergonomic C profile and for the knee rail designed with a tubular profile (not corrugated as in the standard version). The connections between the elements are achieved with rivets and steel bolts. To make simple and quick the assembly of handrail systems, a series of accessories has been developed to facilitate installation. All handrails are supplied in standard grey (RAL 7035) or yellow (RAL 1018). On request, they are available in other colours and resins.

Fences are made with fibreglass gratings and profiles and are mostly suited for use in areas where electrical isolation, resistance to chemical or atmospheric agents are required. They are also an excellent solution for the airport sector for their non-magnetic and radiolucency properties. Standard colours are grey or green, but on request they can be supplied in different colours. On request the top extension arm is also available.

Fixed ladders are entirely made of isophthalic resin and fibreglass (FRP) and their wall installation is performed through FRP or stainless steel brackets. Also the screws for assembling the safety cage are made of stainless steel. Fixed ladders are of different types: 1. ladders serving machinery or plants in accordance with UNI EN ISO 14122-1/4 and tested according to UNI EN 131-2 standard; 2. ladders suitable for use in direct contact with drinking water; 3. double stringer ladders for inspection manholes with the CE marking in accordance with UNI EN 14396 standard.

Ladders, walkways and work platforms are built with pultruded profiles, FRP gratings and stainless steel accessories in accordance with EN ISO 14122 standard (Permanent means of access to machinery) within the framework of Directive 2006/42/EC (Machinery Directive). They have been conceived and designed to best meet the needs of each customer. They are entirely prefabricated in the factory and supplied in pre-assembled modules. Thanks to their lightweight (the specific weight of fibreglass is about 1/5 of that of steel) they can easily be installed on existing structures, without these having to be modified. The absence of maintenance and durability ensure a drastic reduction in operating costs. The characteristics of the materials used and the careful planning allow to create safe structures in compliance with the latest regulations in the field.

BENEFITS of composite manhole covers: theft prevention, noise reduction, resistance, lightness, electric insulation, resistance to corrosion. FRP manhole covers of M.M. are manufactured in accordance with the EN 124:2015: A15 (test load 1.5 ton) Areas which can only be used by pedestrians and pedal cyclists, B125 (test load 12.5 ton) Footways, pedestrian areas and comparable areas, car parking decks, C250 (test load 25 ton) For gully tops installed in the area of kerbside channels of roads which when measured from the kerb edge, extend a maximum of 0.5m into the carriageway and a maximum of 0.2m into the footway. D400 (test load 40 ton) Carriageways of roads including pedestrian streets, hard shoulders and parking areas, for all types of road vehicles.

Gates are made of profiles, fibreglass gratings and stainless steel accessories. The swing leaves size can be adapted to customer needs. Gates are available in the following versions: • gates for driveways with two swing leaves and manual closing - CE marked • pedestrian gates with one swing leaf and manual closing FRP gates for driveways bear the CE marking in compliance with Regulation (EU) No. 305/2011. Tested in accordance with UNI EN 13241-1 standard.
