The Half Round Gutters Roll Forming Machine is designed to produce various types of half-round gutters used in residential and commercial roofing drainage systems. Engineered for high precision and customizable output, this machine can fabricate multiple gutter profiles with fast changeover capability—making it the ideal choice for contractors, builders, and manufacturers looking to serve both traditional and modern architectural styles.
Types of Half Round Gutters
This roll forming machine is compatible with multiple popular half-round gutter styles:
European Bead (Single Bead)
A classic design with an outward-curled front bead and an open hem at the back. Commonly used with copper and zinc materials.Double Bead Half Round Gutters
Features a curled bead on both the front and rear sides. Typically used in custom heritage or high-end residential projects.Reverse Bead Gutters
A modern industry standard where the front bead curls inward, allowing the use of cost-effective metals such as painted steel or aluminum, while hiding the unfinished metal side.
All the above gutter profiles can be produced on a single machine with quick switching tools, reducing downtime and increasing output efficiency.
