metallankare

Metallankare is a term used to describe metal devices designed to anchor or fasten components to a substrate or to secure objects in place. Although the term is used in several languages, it generally refers to hardware such as anchors, bolts, and rods made of steel or other metals that derive their holding power from mechanical deformation, chemical bonding, or a combination of both. Metallankare are used in construction, civil engineering, geotechnical works, and maritime operations.

There are several broad categories. Mechanical anchors rely on expansion, wedges, or thread engagement to grip the host material in concrete, masonry, or rock. Chemical anchors use adhesive resins to bond a steel element to the surrounding substrate, providing high pull-out strength. Rock and soil anchors involve steel bars or cables that are fixed to rock faces or soil masses to reinforce stability, often with grout or resin.

Materials and protective coatings vary; common choices include carbon steel, galvanized steel, and stainless steel, selected for strength and corrosion resistance in the service environment. Installation typically requires proper substrate assessment, correct hole drilling, appropriate anchor size and type, and, for chemical anchors, resin cure time; tightening torques are specified by the manufacturer or standard codes.

Metallankare are subject to safety norms and standards that govern design load, installation practices, inspection intervals, and degradation assessment. Their reliability depends on correct selection for the substrate, proper installation, and ongoing maintenance.
