I did talk to the fabricator late again yesterday telling him the process and what the rough results were from a RAM analysis. I do have RAM Structural System and I was able to find them under the term C-Beam (I always thought they were SMI joists or something like that). Has anyone used the castellated beam systems recently and do they know of any manufacturers in the United States/Canada? RE: Castellated Beams sbisteel (Structural) 2 Apr 21 19:28 I also know that there used to be a company called SMI joists that used to produce castellated beams (I think they went out of business a few years ago). I know AISC has a design guide in relation to castellated beams. The conversation revolved around alternatives to open-web steel joists and was centered around castellated beams. I had heard from a few clients that securing reasonable delivery times on open-web steel joists was becoming and issue with projects orders being placed now but not being delivered until late August. The contact was actually someone I used to work with about 10 years ago and we have kept in touch periodically.ĭuring our conversation he expressed concern in regards lead times for delivery of open-web steel joists. I was contacted by a fabricator recently in regards to helping them with some projects.
