Roof gutters and rainwater downpipes

Gutters are used for the collection of rainwater. The rainwater is guided through downpipes into a sewer, other disposal point or collector. Gutters are produced in many variations and their use is various. In general, gutters are available in different forms and numerous  applications.

The suspended gutter has a semi-circular cross section, which in the past was made using a piece of round wood. The box gutter has a slightly trough, or box-shaped, cross section. The diagonal gutter has a back height edge in line with the surface of the sloping roof, and a front height edge, which forms a right angle, in other words a ‘diagonal’ design.

Downpipes are produced in various types. The most common is the round tube, but tubes with square, rectangular and other forms can be applied. The standard rainwater downpipes come with a soldered seam or a double seam. The diameter of the tubes is extended at one end so different lengths can be put together. To complete the drainage system the gutters and pipes must be fitted together with end pieces, brackets, bends, gutter outlets etc.
