With reference to SMACNA Duct Construction Standard, in page 20 of Appendix A under the heading: 'Sample Shop Standards for 2" W.G. Pressure Class what are the 'brake shop' and 'coil line' referred to in the tables? Why are there separate tables for each?
Also how can a zee channel/bar be used to stiffen a duct joint?
Thank you,
