Structural Foam

What is structural foam and are these rubbermaids what everyone uses?

Many, many reefers do use them. I'm not sure what plastic they use. The term "structural foam" does not really imply a particular plastic, but the tanks itself probably have a recycling code on the bottom. Maybe someone with one remembers what it said (before they filled it :D).

I use 2 x 44 gallon Rubbermaid Brute trash cans connected with bulkhead connectors for my sump, limewater storage, RO/DI storage, and new salt water storage.

I know this is an old question, but the word from Rubbermaid is that these tanks are HDPE.
