There are several types of steel channel connections used for column framing, including welded connections, bolted connections, and pinned connections. Welded connections involve welding the steel channels together to create a strong and rigid joint. Bolted connections use bolts and nuts to secure the channels together, allowing for easier assembly and disassembly. Pinned connections utilize pins or dowels to connect the channels, providing flexibility and allowing for relative movement between the connected members.
