Description
Dromet PSRe M8x90/20 galvanised ring expansion anchor for concrete
Dromet PSRe M8x90/20 ring expansion anchor is a proven solution for permanent fixing of structures in concrete substrates. Designed for professional installation of profiles, metal structures, grating platforms, handrails, machinery and other facility equipment. Thanks to its European Technical Approval ETA 05/0242, CE certificate and national approval AT-15-7574/2008, it guarantees compliance with building standards and full design responsibility.
Construction and material
The PSRe anchor features a ring construction ensuring even expansion in the mounting hole and high anchoring load capacity. Made of structural steel with corrosion protection in the form of electrolytic zinc coating. Supplied with a nut and washer — the anchor is ready for immediate installation without the need to purchase additional components.
Application
The anchor is designed for fixing in substrates made of non-cracked concrete min. class B20 (C16/20), natural stone with a dense structure and solid brick. Ideal for installing support structures for photovoltaic panels, mounting rails, fixing balustrade posts, foundation work for equipment, and any connections requiring high load capacity and certification.

Installation recommendations
The mounting hole should be drilled perpendicular to the substrate surface and thoroughly cleaned of drilling dust. The fastener should be inserted into the hole using light hammer taps. Installation should be carried out using a torque wrench — this ensures the correct tightening torque and proper anchor expansion. After the fastener has expanded, the washer under the nut should be firmly pressed against the fixed element. The parameters specified in Technical Approval AT-15-7574/2008 must not be exceeded.
