Resin construction profile

GRPglass-reinforced plasticfor ladders

Product information
MEISER GRP construction profiles are an alternative to conventional building materials such as steel, aluminium, timber and concrete. A compact range of profiles enables multiple industrial and civil applications, including stair treads, platforms, catwalks and ladders.

Standards and materials
All MEISER profiles are manufactured to EN 13706. Unsaturated polyester resin is the standard matrix material. Reinforcing glass fibres are arranged longitudinally as rovings and transversely as reinforcing mats. A thermoplastic surface veil completes the laminate. Standard colour: grey (similar to RAL 7032). Production is certified to ISO 9001:2015 and monitored by independent testing institutes.

Certifications and approvals
Standard MEISER GRP construction profiles hold EBA approval according to TM 2010-354 I.NVT 4, permitting their use as substructures for signal platforms, catwalks and staircases in Deutsche Bahn AG infrastructure.
