Why Are Old Galvanized Gutters Better Than New

Chlorine based bleaches can destroy the oxide layer on stainless steel but not with galvanized.

Why are old galvanized gutters better than new.

Steel gutters can stand up to ladders and fallen branches better than aluminum. But even thick galvanized steel eventually rusts through. Aluminum gutters resist rust better and last longer than steel. When comparing stainless steel to galvanized steel cleaning is much easier for galvanized than stainless.

As far as installation both types of steel are relatively easy to install but galvanized steel weighs less and is easier to cut. Galvanized gutters have an extra layer of coating that adds protection against the rainwater the weather and other physical damages. Aluminum also dents more easily if hit by tree limbs or hail or if a ladder is leaned against it. Installation is fairly easy because aluminium is lighter than galvanized steel.

However they still need to be repainted about every 10 years. And at 5 to 9 per linear foot installed they re still relatively inexpensive two reasons why aluminum has the edge in popularity according to lyle brandt of all. Aluminum gutters however never rust. This kind of gutters has been used in drainage systems for more than 150 years thanks to properties like corrosion resistance low cost and structural straight.

Aluminium gutters resist rust better than galvanized steel gutters and the metal won t thin over time. While both materials can be customized to form seamless gutters aluminium is slightly easier to work with.
