• Hot dip galvanized steel lasts four times longer than painted steel

• Galvanized barriers can remain corrosion- and rust-free for 40 years

• Painted steel will corrode from both inside and out when exposed to moisture or corrosive elements

• Galvanizing forms a metallurgical alloy as zinc flows inside the tubing as well as outside

• A zinc coating is applied to the steel by immersing it in a bath of molten zinc (at 850 degrees)

• Barriers are carefully cleaned prior to galvanizing to ensure 100% coating

• Molten zinc naturally reacts with the surface of the steel to form a series of zinc-iron alloys that protect the underlying steel from corrosion

Avoid This
Many non-standard "knock-off" barriers are only painted, not hot dip galvanized. The paint is only a cover - it will chip and peel, and then corrode from the inside.

Specify barriers that are hot dip galvanized to guarantee that you'll receive long-lasting, corrosion-free barriers. For more details on the galvanizing process, visit the American Galvanizers Association.
