Galvanized Steel Half Round Gutter Systems FAQ

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.
