Cast-In Anchors
Anchor Channels, Headed Studs & Ferrule Systems
Cast-in anchors are embedded in concrete during the pour, before the concrete sets. They include anchor channels (continuous profiled steel channels cast into concrete edges or soffits), headed studs (welded to steel elements and encased in concrete), and ferrule systems (threaded inserts cast into precast panels or slabs). Cast-in systems provide the highest capacity and most reliable performance because the anchor element is fully encased in concrete.
Anchor channels (such as the Hilti HAC system) are widely used in Australian commercial construction for facade connections, cladding support, services mounting, and structural connections to precast elements. They allow post-pour adjustment of the connection point along the channel length, providing construction tolerance that post-installed anchors cannot match.
While cast-in anchors are not "tested" in the same way as post-installed anchors (they cannot be proof-loaded after the concrete has set around them), ATA provides advisory services for cast-in anchor design verification. Testing requirements arise when the concrete strength is uncertain, when the cast-in anchor has been damaged during construction, or when the connection capacity needs to be verified for a change of use.
ATA provides anchor design advisory services for cast-in anchor systems. While cast-in anchors are not typically proof-loaded in the field, ATA advises on design verification, capacity calculations per AS 5216:2021, and testing strategies when cast-in anchor performance needs to be confirmed.
