Technical information and application instructions

The following information should help you install Roofinox stainless steel the right way

 
 
 
 


Which product?

The answer to this question depends on different factors. Where is the building located? How will Roofinox be applied? What surrounding influences will Roofinox face?
Rural, urban or industrial environments are generally distinguished, but also low or high air pollution and costal or marine areas. The choice of Roofinox stainless steel has to be made accordingly. We can provide the proper alloy for all these applications. You will find more information about this in the technical datasheets.



Soldering

Roofinox® stainless steel is readily solderable with suitable tools. The surfaces to be joined must be free of grease, dirt or other foreign matter. Dirt makes soldering difficult and must be removed before work Begins. Further information can be called up on the appropriate section:

Corrosion

Roofinox stainless steel is a rust free steel. The degree of corrosion resistance depends on the alloy. The alloys 304 and Roofinox tin-plated are generally appropriate for normal areas upcountry, with low industrial and no marine exposure. Areas of application include conventional use on roofs and for roof flashings. Two exceptions occur:

– extraneous rust, adhering carbon steel (normal steel) particles resulting from grinding, brushing, angle grinding, welding beads, dripping rusty water, or steel tool abrasion will lead to rust and later on to pitting corrosion

– Chloride, be it chlorine (e.g. from cleansers), salt, or de-icing salt will affect and pit the metal, this can lead to rust

What needs to be done? If the substrate did not rust through, a suitable cleanser will remove it. Rinse immediately after cleaning with fresh water and the passive layer will reestablish. The stainless steel remains fully functional after this, but pay attention to remove all of the offensive element.

The increased stress for the metal in marine environments, heavy industrial surroundings, or for base and foundation flashings where de-icing salt is expected requires the Roofinox alloy 316L.



Processing

Roofinox® and Roofinox® tin-plated can be installed and processed at low temperatures without particular measures. Even sub-zero temperatures will not lead to cracking or crazing. Preheating of Roofinox® and Roofinox® tin-plated is not necessary. Roofinox® and Roofinox® tin-plated are processed with conventional tools and machines. Make sure to clean tools and machines from rust, steel and other metallic particles. Working tables should be cleaned before use. Stainless steel tools are recommended as they don’t leave rust-causing shavings, extraneous rust particles and facilitate processing.

Roll-forming and seaming machines have to be set on stainless steel processing, consider manufacturer’s instructions. Upon request machine manufacturers provide instructions for the processing of seamable stainless steel.



Weathering

Roofinox stainless steel is a rust free steel. The degree of corrosion resistance depends on the alloy. The alloys 304 and Roofinox tin-plated are generally appropriate for normal areas upcountry, with low industrial and no marine exposure. Areas of application include conventional use on roofs and for roof flashings.
Furthermore Roofinox stainless steel is market leader in regions where rough weather conditions put high demands on roofing materials. The company’s origin and strongest presence is in the European Alps, where wind, rain and snow constantly challenge a roof.



Cleaning

Roofinox stainless steel is easy to clean. Depending on the degree of pollution different cleaning options exist. The natural cleansing effect of rainwater is generally sufficient. If not pressure washers can be used applying fresh water and keeping enough distance to prevent damaging the panels, joints, or water penetration through seams.
