What Is Beaded Half Round Guttering?

Beaded half round guttering features a semi-circular profile like traditional half round systems, but with an added raised bead along both edges. This subtle enhancement creates a more pronounced, decorative finish, enhancing the architectural detail of period homes, cottages, manors, and listed buildings.

It’s a sought-after profile for conservation projects and ideal for replicating original 19th-century cast iron systems.
