I’m working on a wastewater treatment facility and trying to figure out the best material for the roof framing.
Is it common to use wood trusses (even if pressure-treated or fire-retardant), or is steel — cold-formed — the standard in these types of buildings?
The structure will be exposed to high humidity and possibly corrosive conditions for its entire life, so I’m leaning toward galvanized cold-formed steel trusses for durability and non-combustibility. Just not sure if that’s typical or overkill.
Many thanks for any advice.
