Brazing Services: Surface Considerations For Architectural Stainless Steel

Architectural stainless steel plays a significant role in the dimensional stability and appearance of many buildings. When the metal appears on the exterior of a building, special care must be taken to ensure that its finish has the right anti-corrosive and aesthetic properties. If you need stainless steel assemblies for architectural use, a provider of brazing services can be a wealth of information for how to prevent the assemblies from corroding and ensure that they have the right appearance.

The manner in which stainless steel is treated for aesthetic purposes can affect its anti-corrosive properties, and measures performed to strengthen the metal’s corrosion resistance can affect its appearance. When you dialogue with a provider of brazing services about how give assemblies the correct appearance and corrosion resistance, it is good to inquire about how the orientation of polishing procedures, the features of the assemblies, and their surface finish impact corrosion resistance and appearance.

Orientation of Polishing

Orientation of polishing refers to the direction of the motion with which metal is polished: up and down, side to side, or diagonally. Ideally, stainless steel should be polished with an up and down motion relative to the final position of the metal on the building. Using an up and down motion ensures that polishing lines are in a position where rainwater can help keep them free of substances that could precipitate corrosion by invading tiny crevices. 

Features of Assemblies

To avoid creating areas that can be invaded by substances that precipitate corrosion, exterior stainless steel should not be formed into ledges that allow water to sit on a flat surface, or have horizontal grooves or perforations that allow substances to accrete and potentially precipitate corrosion. Slanted ledges that facilitate faster water runoff and vertical grooves that help prevent accretions are better options. Perforations should be avoided entirely.  

Surface Finish

Many customers wish to supply stainless steel assemblies with an exceptionally bright finish. However, depending on the size of an assembly and where it is positioned on the building, a medium surface finish may be the optimal choice. For example, if large panels of stainless steel are used on the roof area, giving them a shiny finish may cause them to be blinding in the sun. A provider of brazing services will advise you on the best type of finish for stainless steel pieces in relation to their position on the building.
