GRP Construction Profiles
Using a comparatively small range of standard profiles, a wide variety of structures can be realised, including stairways, platforms, gangways and ladders.

As standard, the profiles are manufactured using unsaturated polyester resin reinforced with longitudinal glass fibre rovings and transverse glass fibre mats. An additional thermoplastic surface veil provides a high-quality finish while increasing resistance to environmental influences.
The standard colour is grey, comparable toRAL 7032.
Production is certified in accordance with ISO 9001:2015 and regularly monitored by independent testing institutes to ensure consistently high product quality.
All standard MEISER GRP structural profiles are also approved by the German Federal Railway Authority (EBA) in accordance with DBS 918 010, making them suitable for signal platforms, walkways and stair systems used by Deutsche Bahn.
