GRP grates are manufactured using injection molding technology and are produced in various sizes to provide the ideal solution to various installation problems. They consist of monolithic panels that are very easy and quick to install.

GRP grates are mainly used for walkways, maintenance platforms, walking surfaces, channel covers, sewage drains, electrical protection panels and steps.

M.M. gratings are designed with high safety factors and manufactured under the most stringent inspection procedures according to the DIN 24537 -3 standard.

GRP grates can be supplied with a non-slip surface certified according to DIN 51130 (determination of non-slip resistance) in the following versions:

1. with permanent non-slip surface (“meniscus” type) (certified R13-V10)
2. with permanent non-slip quartz coated surface (certified R13-V4)

M.M. the grates were certified as durable products, whose mechanical performance did not decrease according to heat/cold and humidity cycles according to the UNI EN ISO 9142 standard.

M.M. the grates have also passed the aging resistance test with UV cycles according to ASTM G154.

Upon explicit request, flame retardant grates can be supplied according to standards EN13501, ASTM E84, ASTM D635, DIN 4102, NFP 92-507.

M.M. grates can also be delivered with a non-slip coated surface (certified R10 – V10)
