We often suggest that castings may be appropriate in any of the following circumstances, with the suitability of castings increased where more than one of these conditions applies:

• Complex connections (i.e., with incoming members at different angles, or at sharp angles where weld access is a problem)
• Connections subjected to very high loading, where large welds are required but would be difficult to apply and inspect, or where connections require significant stiffening
• Architecturally exposed joints, particularly for HSS connections
• Fatigue-critical connections
• Repetitive details
