Zinc roof gutters are used for the collection of rainwater. The rainwater is guided through the gutters and downpipes into a sewer, other disposal point or collector. Gutters are produced in many forms and variations for numerous applications, such as suspended and box gutters, , concealed gutters and valley gutters.
The standard roof gutters are divided into suspended and box gutters. The suspended gutter has a semicircular cross section, which in the past was made using a piece of round wood. The box gutter has a box shaped cross section.
Zinc downpipes are placed under the zinc gutter and enable the collected rainwater to drain further to the sewer system or other disposal points. Rainwater 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 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.
