An industrial piercing (North America), sometimes called the " bar " (UK/IRL), scaffold piercing or construction piercing, is any two pierced holes connected with a single straight piece of jewelry (compare to orbital piercing); however, it typically refers to a double perforation of the upper ear cartilage specifically. Two piercings are made, one fairly close to the head (forward-helix piercing) the second further down the helix, on the opposite side of the ear (helix piercing) A vertical industrial piercing is also referred to as a suicide industrial.
Industrials piercings are usually 14g, and the barbell jewelry is worn during the healing period. Sometimes, a pair of captive bead rings (CBRs) are used instead, and are exchanged for a barbell after healing is complete. Although the use of CBRs often results in faster healing, proper alignment of the piercings is difficult when this technique is used. Industrials typically take anywhere from six months to one year to fully heal and are considerably more painful than conventional piercing.
