Half round gutters get their name because of their shape. There are 2 types of half-round gutters:
European Bead / Traditional Single Bead – This was the standard, and is the old fashioned way to make gutters. The front bead curls out (a manual process), while the back of the gutter features an open hem. This gutter is commonly sold in copper or zinc.
Double Bead Half Round Gutters – The old fashioned way to make half round gutters, with the curled bead in the front and back side of the gutter. Manufacturing can be done in up to 19.5′ lengths. This gutter can be secured / installed via double bead hangers with rods.
Reverse Bead Gutter – The new industry standard. Reverse single bead gutters allow for more economical materials, such as aluminum or steel to be used. This is due to the front bead curling in, and not revealing the other side of the metal, which is normally not finished.
