Galvanized gutters are made from hot dip steel and have been effectively used for more than 150 years.
Galvanised steel guttering rust.
Installation is fairly easy because aluminium is lighter than galvanized steel.
However aluminum resists it slightly better than galvanized steel.
The value of hot dip galvanizing stems from the relative corrosion resistance of zinc which under most conditions is considerably better than iron and steel.
Galvanized steel has been used for almost 2 000 years because of its unrivaled ability to last a very long time and resist rust.
Gutters transport rainwater away from your home s foundation to help prevent leaks and water damage.
Left untreated white rust corrodes the zinc and the metal underneath begins to rust exhibiting the more traditional brownish red color.

Gutters made of galvanized steel are strong and durable but they re no longer as popular as they once were because of their susceptibility to rust after a few years.
Aluminum gutters can develop holes too.
If the item is exposed to continually wet conditions the zinc develops a film known as white rust.
You can use the same process for repairing holes in both steel and aluminum gutters.
Aluminium should last longer than galvanized steel.
Aluminium gutters resist rust better than galvanized steel gutters and the metal won t thin over time.
Galvanized metal is coated with a layer of zinc to protect the iron or steel underneath.
Although they probably won t rust aluminum can be punctured more easily than steel gutters.
While both materials can be customized to form seamless gutters aluminium is slightly easier to work with.
Both aluminum and steel gutters resist rust.
This zinc is easily scratched off and the scratches are difficult to see.
Sometimes rust corrosion can eat all the way through galvanized steel gutters.
