What makes European half round gutter and rainwater systems so extraordinary is: longevity, strength, efficacy and ease of maintenance.

Because there are no corners in European half round gutters, expansion from freezing and thawing is not an issue as it is for K style and box gutters. Because the gutters are round, expansion from ice simply at worst, slides up, expands above the rim and either self removes or can be removed manually, whereas, K style or box gutters build up ice strata which go all the way to the corners and have no where to go as they are locked in place. Expansion and contraction over time result in broken gutter.

Half round gutters make maintenance easier, too. Debris is much more easily flushed away in a half round rainwater system than a K style gutter where dregs are more readily trapped and locked in place.

In addition, because of their round feature, European half round gutters ease the flow of rainwater better than their box counterpart. This means, during a deluge, water flows more quickly and efficiently off the roof and out the downspouts.
