Sheet Metal Roof Coverings

Thin sheet metal has been used as a roof covering material for many decades. Often on buildings with increased stress, in exposed locations or with special shapes. Sheet metal roofs are among the most robust, weather-resistant and storm-proof roofs. In modern architecture, sheet metal roofs impress with their versatile usability, their adaptation to any shape and roof pitch, as well as the many material and design variants.

Sheet Metal Roof

Sheet metal roofs impress with their enormous longevity, low dead weight and load-bearing capacity. Double-standing-seam roofs can be realised from as little as a low roof pitch of just 5 percent. With roof structures that have little slope, the use of space can thus be optimised.

With sheet metal roofs, sound expertise is enormously important. The execution of the various details and connections ultimately determines the service life of a sheet-metal roof covering. Rohner AG has a great deal of experience in creating sheet metal roofs. We recommend ourselves as a reliable partner for a long-term watertight sheet-metal-roof realisation. Whether it is a small dormer structure or a large-area sheet metal roof — we have the necessary experience.

Features

Material

The planters are made of aluminium, steel or stainless steel. All materials can be recycled. 

Colour

The metals are powder-coated. Any colour can be powder-coated. Rohner AG has 20 colours in its own range. 

Dimensionally Stable

Thanks to the right choice of material and the cross-bracing, the planters are dimensionally stable.

Resistance

The planter is weatherproof and winter-hardy thanks to the insulation. The temperature inside the planter never drops below 0°C.

Drainage

The Rohner planter is drained at the bottom through a drainage pipe. For lasting function, the drainage pipe is protected with a drain guard.

Water Level

At the bottom of the planter there is a 60 mm water level. This imitates groundwater and is important for the artificial ecosystem. 

Protection

Thanks to the highly weather-resistant colours, your planter will not fade. We can offer over 10 years of warranty on the colour fastness. 

10-Year Warranty

Rohner can offer a 10-year warranty on the Rohner planters.
