Double Longitudinal Seam in duct section
Double Longitudinal Seam in duct section
(OP)
We have installed two pieces of SMACNA class 1 round galvanised duct 900 diameter with double longitudinal seams in each section. Please confirm if this is acceptable practice according to SMACNA and if so where I can prove this.

so your shop would have to use two 5x 10 sheets to get you a 10 foot section. your alternative would be spiral wrap, or shorter duct sections.
