Gored Segmented Elbows for Ducting
Segmented elbows, also known as gored elbows or gored segmented elbows are available in galvanized, stainless steel, and carbon steel in ALL duct gauges and radii.
Essentially the name says it all. These are segments that are then joined together by welding or mechanically locking the segments together. The mechanical method incorporates a machine that forms the ends of the segments (gores) so that one segment fits into the other and then mechanically locks them together. Because the metal is being formed, 18 gauge is the heaviest metal for this mechanical locking method. Heavier gauge metal requires that the segments be welded.
The ends of the elbow can be fitted with flanges or rolled lips or left raw for welding.
