The RHEINZINK double standing seam
The double standing seam as a system for the roof covering has its origins in the related hollow seam and single standing seam systems. It is a further development of a tried-and-tested system that can be used more favourably in some areas. However, excellent product quality is not the only important aspect for RHEINZINK. Our double standing seam system is also optimised with regard to other areas. Planners and architects benefit from a clearly defined product programme that includes scope for individual solutions as well as the standard products. Refined system technology makes installation of the double standing seam system effortless and cost-effective, which will satisfy the clients of planners and architects. It is particularly simple to install on new buildings. In contrast, it is the flexibility of double standing seam systems that make them ideal for refurbishing existing buildings. Suitable solutions that reduce the complexity of planning and simplify calculation are available for unusually shaped buildings and building elements.

Features of RHEINZINK double standing seams
Double standing seam coverings have many impressive benefits. The following product features are particularly noteworthy:
- The particularly delicate seams have an attractive, slim appearance and ensure the harmonious integration of roof surfaces in traditional or moderner buildings
- Double standing seams are ideal for shallow roof slopes and can be used starting from a gradient of 3°.
- They can be perfectly adapted to various building elements for existing buildings with more complex architecture. Tapered, concave or convex rounded surfaces can be accurately formed
- Standing seam panels up to 7 m long are economical to fit. Panel lengths of up to 16 m can be flexibly employed, including on roofs with large surface areas. We can provide rental machines for processing greater lengths on site.
- The seams are rainproof and so protect the building structure against wind and weather
Planners and professional specialists can also decide whether to produce the double standing seams manually or using a profiling machine.
Double standing seams planning and application
System description
- Roofing from 3° (approx. 5.2%) roof inclination
- Use of seam sealant tape on roofs with inclinations from 3° to 7°
The double standing seam can be fitted on roofs with inclinations from 3°. Seam sealant tapes must be used on roof inclinations from 3° to 7° and where there is a danger of ice dams forming near the eaves. The profile edges are produced using roll formers or by hand. The seams are also sealed using a seam sealer machine or by hand.
The installation of pre-profiled double standing seam panels has become established as an international standard. Roof surfaces can be very finely segmented thanks to the seam height of approx. 25 mm and slender seams.
Concave and convex rounded surfaces can also be easily roofed using double standing seam systems.
Double standing seam systems are of impressive product quality and are based on well-engineered system technology. For instance, perfectly matching sealant tapes are available for roofs with low gradients and are especially necessary in regions where snow and ice are common.
Double standing seam systems are attached using fixed and sliding clips made from high-quality stainless steel. The screws are corrosion-protected and also fulfil the high requirements for a long-lasting roof covering. The RHEINZINK CLIPFIX autofeed screwdriver and specially developed RHEINZINK clips are available for rapid and stormproof assembly. All relevant technical details can be downloaded from our web page.
Dimensions and metal thickness
- Standard panel width approx. 530 mm (coil width 600 mm)
- Common panel widths 400 mm to 600 mm
- Metal thicknesses 0.7 mm/0.8 mm
- Normal panel length up to 10 m
- In special cases up to 16 m
- Standard transport length is 7 m
The international standard size for roofs in double standing seam systems is a panel width of approx. 530 mm (coil width 600 mm) and a metal thickness of 0.7 mm. We recommend limiting the panel width to 430 mm and the metal thickness to 0.8 mm for mono pitch roofs with overhangs based on practical construction experience. This measure prevents noises that can occur in strong winds due to the natural curvature of the panels.
The generally common maximum panel length is 10 m. Using our clips, this can be extended to 16 m. However, the roof inclination then remains limited to max. 30°. In this case, panel attachments and connection details must be adapted to the increased length variation.
If the max. possible panel length is insufficient, individual lengths can be connected using cross seams.
Customised forms
- Convex and concave rounded panels
- Tapered panels
The minimum radius for convex rounded, standing seam panels is 0.6 m. Starting from a radius of 12 m, panels can be installed without first pre-rounding them. If the radii are smaller, the panels must be edged by hand and stretched using manual forming pliers or a Biegeboy bending machine.
For concave rounded surfaces, the seam edge must be compressed, which is more technically difficult than stretching. The minimum radius for concave rounded, standing seam panels is, therefore, 2.5 m. Pre-rounded panels cannot be installed above a radius of 25 m.
Tapered panels are used to construct roofs over round floor plans or for special details in roof valleys. For reasons of production feasibility, the panel width of tapered panels must be at least 100 mm and max. 730 mm, depending on wind loads. The max. panel width of 530 mm must be adhered to for mono pitch roofs.
