Everything You Need to Know About Galvalume®

Choosing the right material for a new gutter installation is a big decision.  What makes the choice even more difficult is the many options available on the market today. Depending on your customer’s preference and budget, galvanized steel, aluminum, copper, and vinyl are all viable solutions.  Another material to consider is Galvalume® steel.   For many contractors, this product is the preferred choice for their gutter supply needs.  Below are a few of the frequently asked questions we receive on Galvalume®.

What is Galvalume®?
Galvalume® is a material constructed of steel coated with 55% aluminum and 45% zinc during a continuous hot dipping process.  This unique coating protects the steel from corrosion while creating a tough, long-lasting finish.  Galvalume was first manufactured in 1975 and has been thoroughly tested in many types of environments.
What are the benefits of using Galvalume®?
There are many reasons why Galvalume® Steel has become a popular alternative to standard aluminum gutter systems.  Here are some of its benefits:
·         Corrosion Resistant
·         Strong & Durable Metal
·         Resistant to Fingerprints & Smudging
·         Weathers Uniformly
·         Cuts & Bends are Protected
·         Roll-formed Dry & Oil-free
Which accessories can I use with Galvalume®?
It is best to only use accessories that are as resistant to corrosion as Galvalume®.  Below is quick guide on which accessories are best suited for use with Galvalume® steel.
          Stainless Steel
          Aluminum Pop Rivets
          Stainless Steel Screws
          Zinc-coated Screws (can be used but zinc coating is slightly less resistant to corrosion than Galvalume®)
How does Galvalume® compare to Galvanized Steel?

  1. Can a 2 too 1 mixture of bleach and water cause corrosion on galvalume gutters. I was told that washing them with bleach and watch causes them them to have black corrosion spots and more

    1. Thanks for your comment Richard. We would recommend not using bleach on Galvalume. Bleach, even when mixed with water, is very corrosive to Galvanized Steel. Although Galvalume has an Aluminum and Zinc coating, probably best to stay away from bleach and use a mixture of 1 part Ammonia and 10 parts water and rinsing with fresh water and allowing to thoroughly dry.
