We simplify the design and enhance the performance of structures by enabling Architects and Engineers to use cast steel connections. We take pride in collaborating in the creation of safer, innovative, and more beautiful built environments.
CAST CONNEX® is the industry leader in the use of cast steel structural components in the design and construction of building and bridge structures. Our products include pre-engineered connectors that simplify the design and enhance the performance of structures. We also offer design and design-build services for custom cast steel nodes and components.
As fabrication of true-pin connections to hollow structural section (HSS) members is difficult, particularly when aesthetics are a concern, the use of Universal Pin Connectors vastly simplifies the design, detailing, and fabrication of critical architecturally exposed structural connections and significantly improves the aesthetic value of the finished assembly.
Universal Pin Connectors are a complete connection solution, as they are supplied with the associated carbon steel pins and electropolished stainless steel washers, cap plates, and cap screws.
Fabrication of hollow conical steel tapers is difficult, and often times steel contractors will shy away from projects calling for such details. The specification of CAST CONNEX Architectural Tapers will ensure availability, cost effectiveness, and consistency in appearance and quality.
Also consider specifying Architectural Tapers in conjunction with CAST CONNEX® Universal Pin Connectors in AESS applications that may benefit from clean, pin-type connections.
Diablo Bolted Splices are supplied including drilled bolt holes. All of the fittings can accomodate four fasteners, though our fittings for 12.75-inch (324 mm) outer diameter HSS can also be supplied to accomodate 8 fasteners. Hand wrenches must be used for bolt tensioning in the field. Fasterns and cover plates (if required) are not included.
We leverage steel casting manufacturing to offer our clients unparalleled opportunities for optimization and beauty in structural form. We'll work with you to design your custom cast steel components to ensure that they provide the desired aesthetic, carry loads safely and efficiently, integrate with your structural steel framing, and are castable and economical.
We've been engaged by and provided our services to owners, architects, engineers, general contractors, and steel fabricators in both public and private projects and have provided both design only as well as design-build solutions.

High Strength Connectors are standardized, capacity-designed brace end connectors that accommodate bolted double-shear connection between round HSS braces and a typical corner gusset plate. By eliminating shear lag in the brace connection and standardizing connection details, use of the connectors vastly simplifies connection design. As the connectors eliminate the need to field weld braces to the frame, they significantly speed erection and reduce the cost of special inspection.
There are two types of KBB available those accommodating bolted connection to the beam flange (B-series) and those accommodating welded connection to the beam flange (W-series). Both types are designed to enable field bolting of the beam to the column, thus eliminating field welding. The B-series KBB are particularly well-suited to retrofit, as they offer a weld-free option for addressing seismically deficient steel moment frames.
Each Scorpion Yielding Connector (SYC) consists of specially designed cast steel and fabricated elements which connect to and transmit forces between the end of a traditional brace member and the beam-column intersection of a concentrically braced frame. The SYC remains elastic during ordinary building service loading and provides energy dissipation during a sizable earthquake through the cyclic inelastic flexural deformation of the SYC's cast steel yielding fingers. The system exhibits a full, symmetric hysteresis characterized by an increase in stiffness at brace elongations greater than the design level. This increase in stiffness is a result of the second-order change in geometry of the yielding fingers, each of which is shaped to promote the spread of plasticity along its entire length.
