So are you looking into more of a pipe grid situation ? If you are wondering about Hardware reccomendations for attaching to existing steel structures / I-Beams, there are several options available depending on the aplication, load, and permanance. Actual rigging info, you are not going to find here. If you don't know how to ask what you are looking for you shouldn't be trying to do any rigging in the first place. I, and most here, would reccomend that you contact a Profesional Licensed Rigger or a Stage rigging company. I hope we can help you figure out the information you are looking for.
When you say research project are we talking a hypothetical application, or are you looking into actual contsrtuction techniques.
We're a ery nosey bunch and the more info you provide about what you are doing the much more likely chances we can steer you in the proper direction.
