The present invention relates to a method of isolating column loading and mitigating deformation of shaped metal vessels, the method comprising forming a cylindrical metal tube into a shaped metal vessel, the shaped metal vessel comprising a sealed end, an open end, and an integral carry ring proximate the open end. Column load is isolated between the open end and the carry ring by supporting the shaped metal vessel by the carry ring. The shaped metal vessel is sealed with a closure, wherein deformation of the shaped metal vessel between the sealed end and the carry ring due to column load is minimized during application of the closure.
