High Integrity Blocks

CAST CONNEX® High Integrity Blocks® structural elements are specially engineered and manufactured solid steel sections which simplify the design and fabrication of – and provide unparalleled strength, quality, and reliability in – heavily loaded structural connections.

As a result of intensive research and development paired with careful engineering and manufacturing control, CAST CONNEX is able to design and deliver ultra-heavy, weldable structural steel sections (up to 4-foot x 4-foot cross sections, and up to fifty feet in length depending upon cross-sectional dimensions) which exhibit up to 65 ksi (450 MPa) yield strength and elevated Charpy V-Notch (CVN) toughness in all three directions of loading and through the full cross-section.

Our ability to guarantee through thickness mechanical properties in our High Integrity Blocks products is just as unique in the market as is our material's enhanced resistance to ductile fracture. In particular, High Integrity Blocks structural elements feature a low Carbon Content and an elevated CVN Toughness - two critical factors in enabling structural steel materials to resist fracture in the presence of high triaxiality (Kanvinde and Deierlein, 2006).

Because of the way they are engineered and processed, High Integrity Blocks products are also insusceptible to lamellar tearing. As such, High Integrity Blocks structural elements are ideal for use within the center of multi-axis loaded structural connections where lamellar tearing of hot rolled plate may compromise quality and strength of the connection or where the lamination of multiple steel plates to build up a solid section is not advisable due to the need to transmit forces orthogonal to the laminations.

As High Integrity Blocks structural elements are engineered products (not just a material!), we encourage designers interested in their use to contact us during the design phases of the project for design and specification support.
