Galvanized Steel Half Round Gutter Systems

Our Galvanized Steel Half-Round Gutter Systems offer the perfect combination of strength, longevity, and traditional style—ideal for residential homes and light commercial buildings. Made by Zambelli in Germany, these systems feature high-quality steel protected by a zinc coating that defends against corrosion and extends service life.

Available in 5" and 6" profiles, galvanized steel gutters are a smart choice for areas with moderate to heavy rainfall. The classic half-round shape not only looks great—it also promotes efficient water flow and is easier to keep clean than box-style gutters. Each system pairs with 3" or 4" round galvanized steel downspouts, depending on the size of your roof and drainage needs.

Whether you’re updating a home, replacing worn-out aluminum, or looking for a durable upgrade, galvanized steel gives you the performance you need at a cost-effective price point—all backed by Zambelli’s trusted engineering.

More about Galvanized Steel Half Round Gutter Systems

What sizes are available in galvanized steel?

We offer 5" and 6" half-round galvanized steel gutters, designed to handle a wide range of residential and light commercial roof sizes. These are the most popular sizes for standard installations.

What size downspouts are compatible?

Both 5" and 6" galvanized gutter systems are compatible with 3" and 4" round galvanized steel downspouts. Choose 3" for average roof sizes, or 4" if your project involves steep pitches or larger surface areas that require higher flow capacity.

Will galvanized steel gutters rust over time?

Galvanized steel is coated in zinc, which helps protect against rust. With routine maintenance—such as clearing debris and preventing standing water—galvanized steel gutters can last 20–30 years or more.

Who manufactures these gutter systems?

All components are made by Zambelli, a leading German manufacturer of precision rainwater systems. Zambelli products are known for their tight tolerances, high-quality finish, and consistent fit, making installation smoother and performance more reliable.
