System Description

  • Roof covering from a roof pitch of > 6:12
  • 9:12 in regions with heavy snowfall


The angled standing seam is used for roofs with pitches over 6:12, on facades and for cladding small areas such as  facings, fascias, parapets etc. Its height of approx. 1" and seam width of approx. 1/2" results in attractive visual segmentation of roof and facade areas.

The angled standing seam is characterized by its low material stress levels. Unlike the double standing seam, only one seam is closed here, either mechanically or by hand. 

The angled standing seam can be used to clad tapered areas as well as concave and convex surfaces.

Measurements / Metal Thickness

  • Common panel width 15.7" - 16.7" 
  • Metal thicknesses 0.7 mm / 0.8 mm
  • Standard panel length up to 52'


The panel width of approx. 16.7" is the North American standard for double standing seam roofs, with metal thickness of 0.7 mm. However, given our practical experience with construction we recommend limiting the panel width to 16.7" in the case of monopitch roofs with roof overhangs and using the metal thickness 0.8 mm. This will minimize noise being caused by the natural deflection of panels in high winds.

The usual maximum panel length is up to 33', although in special cases max. 52' is also possible. The roof pitch is however then limited to max. 2:12 here.  In such cases the fixing and connection details for the panels must be adapted to the increased length. 

If the max. possible panel length is not sufficient, individual lengths can be attached with cross-joints.

The usual maximum panel length is up to 10.00 m, although in special cases max.16.00 m is also possible. The roof pitch is however then limited to max. 30° here. In such cases the fixing and connection details for the panels must be adapted to the increased length.

If the max. possible panel length is not sufficient, individual lengths can be attached with cross-joints.

Custom-Shaped Panels

  • Concave and convex panels
  • Tapering panels

The minimum radius for convex standing seam panels is 24". It is possible to install not pre-curved panels from a radius of 40'. With smaller radii the panels have to be folded up by hand and stretched with a hand form tool or bending machine.

Where concave panels are concerned, seams must be folded by shrinking, something that is technically more difficult than stretching. As a result, the minimum radius for concave standing seam panels is 8'. It is possible to install not pre-curved panels from a radius of 82'. 

Tapering panels are used when it is a question of building roofs over curved footprints or providing customised detailing in the case of valleys. The width of tapering panels should be min. 4" and max. 29" depending on the wind loads to ensure they can be produced by hand. A width of max. 21" should be observed for monopitch roofs.

System Fastening

RHEINZINK roof systems use seam techniques that are attached indirectly using fixed and sliding clips. 

Clip spacing and type should be confirmed by a registered engineer.
