Rebar composite: steel takes tension, concrete takes compression and fire cover.
Galvanizing sacrifices itself so the iron does not.
Buy fire resistance without bulky boards on exposed architecture.
Bonded carbon plates strengthen bridges when welding is unwelcome.
If the pairing is wrong, the material will be blamed for a system fault.
