Drainage Capacity of the Gamrat Roof Gutter System
When choosing a roof gutter system, we should make sure whether troughs and downspouts will be able to collect water from the roof area of our building. For this, calculate the so-called effective roof area, which is to be drained by the system.
Maximum surfaces drained by GAMRAT roof gutter systems in sq. m. of effective roof area (per downspout).
