MOLYMER MATEX is a general FRP manufacturing company.

FRP Grating

FRPグレーチング

Multi-purpose lattice material placing importance on customer satisfaction developed in the 50 years of FRP molding production history.

Head Office/Plant in Sagamihara City, Kanagawa features one of the best quality control and design ability in Japan.

For the monument in Zounohana (Elephant Trunk) Park, as part of Yokohama Port 150th anniversary project, our FRP product was chosen as its long-term weather-resistance which can last 20-30 years was recognized.

Used product: GS2525 / flame-retardant type / Milky, clear / less polluting function / fluororesin coating (permeability increases when lit up)

Weather resistance test using arc accelerated exposure tester

Grating destructive test using bending tester


Approximately 1,000-5,000 hours of weather resistance test is conducted to have results checked by customers.

Our products are manufactured under sufficient quality management. However, tests can be performed at customers’ presence if request.
GS Grating – standard
GSグレーチング 規格 GS type can be cut into requested size based on the standard size of 1,007 x 3,007.
PL Grating – standard
PLグレーチング 規格 This is manufactured by combining our original FRP continuous pultruded material “Plalloy” and can meet any design requirements. There are various types from major direction, flat bar, round pipe, square pipe to irregular shapes.
GS Grating – examples of building use
GS Grating - examples of building use GS Grating is used for various design purposes as its durability and weather-resistance increases by coating.
PL Grating – pictures demonstrating the product application
PL Grating - pictures demonstrating the product application PL Grating is a pultruded product and can be used in any size suitable for construction requirements.
GS Grating – examples for civil engineering use
GSグレーチング 土木用途実績写真 GS Grating is used for salinity/chemical resistant or insulation purpose in marine fishery, sewerage treatment plant, chemical plant, or electric power station.
Hikari Pasar – standard/example of the product application
Hikari Pasar is the ideal permeable lattice material for louver as it is 45 degree slanted on grate bar compared to traditional FRP grating.
