Aluminium should last longer than galvanized steel.
Galvanised steel guttering rust.
Galvanized steel has been used for almost 2 000 years because of its unrivaled ability to last a very long time and resist rust.
However aluminum resists it slightly better than galvanized steel.
Aluminium gutters resist rust better than galvanized steel gutters and the metal won t thin over time.
Hot dipped galvanized steel and electroplated galvanized steel are made using different methods and their zinc galvanized coatings corrode completely differently.
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.
Left untreated white rust corrodes the zinc and the metal underneath begins to rust exhibiting the more traditional brownish red color.
Installation is fairly easy because aluminium is lighter than galvanized steel.
Using steel gutters coated with zinc a process known as galvanization minimizes rust and.
Luckily rusted gutter repair isn t too difficult.
While both materials can be customized to form seamless gutters aluminium is slightly easier to work with.
Gutters transport rainwater away from your home s foundation to help prevent leaks and water damage.
Galvanized metal is coated with a layer of zinc to protect the iron or steel underneath.
This zinc is easily scratched off and the scratches are difficult to see.
If the item is exposed to continually wet conditions the zinc develops a film known as white rust.
Aluminum gutters can develop holes too.
Both aluminum and steel gutters resist rust.
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 gutters are made from hot dip steel and have been effectively used for more than 150 years.
Sometimes rust corrosion can eat all the way through galvanized steel gutters.
The protective zinc coating does eventually begin to wear away exposing the bare metal.
