This creates interesting accents on the building, providing variety without compromising the functionality of the roof drainage system.

System technology box gutter

System description

  • Roof drainage system according to DIN EN 612
  • Consisting of gutter, accessories and downpipe
  • Gutter with bead notch for simplified installation

RHEINZINK offers a variety of forms of gutters, downpipes and accessories. RHEINZINK-roof drainage products are manufactured and tested in accordance with DIN EN 988, DIN EN 612 and the QUALITY ZINC criteria catalogue (TÜV Rheinland). Depending on the nominal size, they are available in the surface qualities RHEINZINK-CLASSIC and RHEINZINK-prePATINA.

Dimensions & metal thickness

  • Standard nominal gutter sizes 200 / 250 / 333 / 400 / 500
  • Metal thickness 0.65 mm / 0.7 mm / 0.8 mm depending on nominal size
  • Standard length 3.0 m (other lengths on request)
  • Standard nominal sizes downpipes (square) 60 / 80 / 100 / 120
  • Metal thickness 0.65 mm / 0.7 mm / 0.8 mm depending on nominal size
  • Standard length 2.0 m

The nominal size of the gutter indicates the material cut, please refer to the illustration on the left for the exact dimensions. The nominal size for downpipes indicates the side length of the square cross-section.

According to DIN EN 612, gutters are divided into classes X and Y according to their bead diameter or the corresponding section modulus. Regular downpipes are divided into classes X and Y according to the dimension of the seam overlap. RHEINZINK-gutters and downpipes correspond to Class X and thus also meet the requirements of Class Y.

Fastening

  • Fastening of the gutter with specially manufactured gutter bracket  
  • Connection of the individual gutter lengths by soft soldering or gluing
  • Fastening of downpipes with pipe clamps
  • Alternative: RHEINZINK-Universal downpipe bracket for all nominal sizes and shapes

The gutters are fastened in gutter brackets specially manufactured for this purpose (according to DIN EN 1462). These, in turn, are fixed either to the eaves boarding, formwork, rafter (if necessary also laterally) or to the wall. The gutter must be dimensioned according to local requirements.

Rainwater downpipes are usually fixed to the supporting structure with conventional pipe clamps. The distance between the pipe clamps for pipes with a nominal size > 100 mm is max. 2.0 m, for a nominal size ≤ 100 mm the distance is max. 3.0 m. The minimum distance between the downpipes and the structure is 20 mm.

For further information on the fastening, arrangement and cross-section of gutter brackets, please refer to the brochure "Folding technology - planning and application" in the download area.

Design examples

Pre-hung gutter

  • Roof drainage products according to DIN EN 612
  • Installation with or without slope
  • Dimensioning as a pre-hung gutter in accordance with DIN EN 12056-3

Pre-hung gutters can be installed with or without a slope to the drains. Standing water in the gutters does not constitute a defect.

In the event of a heavy rain event above the design rainfall intensity, emergency drainage takes place via the front edge of the gutter.

 

On-sill gutter

  • Roof drainage products according to DIN EN 612
  • Installation with or without slope
  • Dimensioning as a curtain-type gutter in accordance with DIN EN 12056-3

The on-sill gutter differs from the pre-hung gutter only by the additional installation of a cornice cover, which is, however, technically completely separate from the gutter. If the RHEINZINK-roof drainage accessories cannot be installed, a craftsman's version must be used.

The cornice cover can be attached to a full-surface substructure using adhesive strips or glued. The minimum cross slope of the cover should not be less than 3° to avoid standing water.

Special form rear cornice gutter

  • Gutter as edge profile
  • Exterior and interior design possible

As soon as the rear cornice channel cannot drain to the outside, it is classified as an internal channel. In this case, technical information and the dimensioning of the internal drainage in accordance with DIN EN 12056 must be observed.

In contrast, rear cornice gutters with external function are treated as curtain-type gutters. Depending on the cornice width, the gutter can be designed in one or two parts. The handcrafted box gutter can either be inserted into gutter brackets specially made for this purpose or into a full-surface timber construction.
