Applications

Fastening systems, chemical and mechanical anchors, and Fischer plugs for every type of substrate (cracked and uncracked concrete, solid or hollow masonry, drywall, insulating materials) are fundamental devices in construction and plant engineering. Design is based on Eurocode 2 Part 4 (EN 1992-4) and European Technical Assessments (ETAs) issued according to EAD (European Assessment Document, formerly ETAG 001 for metal anchors, ETAG 029 for multiple applications). Typical materials are galvanized steel, A2 (AISI 304) and A4 (AISI 316) stainless steel for corrosive environments, with dimensioning according to concrete class (C20/25, C25/30) and thread diameter (M6, M8, M10, M12, M16, M20). For fire applications, fire resistances R30, R60, R90, R120 are evaluated. Installations require screws, plugs, and anchors on masonry, concrete, and plaster, using tools (drill bit, blade) for hole preparation on site and in the workshop.
