Here, the gate frame is fully welded and the pickets are riveted to the horizontal rails. The sections that flank the gate also have pickets that are riveted to the horizontal rails.
Update: 01.01.2009: As of some time in 2008 (from what we had been told) Monumental ceased making it's own product line and now subcontracts it's work to Iron World. While we have had only one experience under this arrangement, it was not a good one. We have since decided that it is in our customers best interest to discontinue usage of the Monumental product line until such time it returns to manufacturing it's own product and resumes proper customer relations.
