Отрасли
Transport
Auto bodies, rails, ship plate, containers.
Energy
Towers, pipelines, pressure vessels (with coded alloys).
Tools
Cutters, dies, bearings — often through-hardened or carburised.
Appliances
White goods skins, often galvanized then painted.
Packaging
Tinplate and aerosol cans remain a closed-loop steel stream.

Zinc
Galvanizing sacrifices itself so the iron does not.
Intumescent coats
Buy fire resistance without bulky boards on exposed architecture.
CFRP patches
Bonded carbon plates strengthen bridges when welding is unwelcome.
If the pairing is wrong, the material will be blamed for a system fault.
