Insertion Elements(redirected from insertion sequence)
Also found in: Dictionary, Medical, Acronyms, Wikipedia.
steel elements designed for joining built-up or cast built-up reinforced-concrete structures and products to each other or to other building structures or structural members. Insertion elements are manufactured from round, strip, sheet, angular, and channel steels. In most cases insertion elements consist of separate plates (flat elements) to which are welded straight or bent anchor rods (usually made of reinforced sectional batch steel) embedded in the concrete of the building or structures. The exposed surfaces of insertion elements are protected from corrosion by such methods as galvanizing.
