Why an Anchor Casting rather than a fabricated anchor? • Castings exhibit higher hot strength than fabricated anchors. • Castings have a greater resistance to oxidation than fabricated anchors. • Castings can be less expensive than an equivalently sized fabricated anchor. • Castings exhibit greater volume stability at higher temperatures than fabricated anchors. • Castings will promote longer service life than fabricated anchors in tough applications.
