Brass profiles and sheets grinded and polished

Brass profiles in grinded or mirror polished finish underline the noble warm character of the material. Brass is made of copper and zinc as the main alloy components. The zinc content determines the colour and differs between lighter or darker golden yellow colour.

If the zinc content is less than about 20%, the colour changes to a brownish to red hue. If the zinc content exceeds 36%, the colour will change from pale yellow to almost white yellow. Brass is slightly harder than copper but less hard than bronze.

Brass profiles polished and gilded

Gilde brass profiles get the best protection against corrosion

With unprotected brass surfaces you should note that the oxidation with oxygen leads to colouring of the surface. The handling of brass profiles means that gloves have to be worn at every processing step. Alone the sweat of the skin is enough to negatively influence the colouring of the surface.
How can you protect brass profiles in polished or highly polished finish? There are several ways to protect ground or polished brass surfaces.
The simplest kind, but care-intensive would be to brush it every day.
The simple protection by Zapponlack takes the brilliance and value representation of the highly polished brass surface. Industrialized options include powder coating. However, the surface becomes more creaky and dull than the beautiful material actually gives. The best surface protection would be to gild the profiles.

Brass pipes are often used as handrail or showcase components. Brass surfaces have a bactericidal effect so no bacteria can settle, making brass the ideal material for door handles and handrails. Through different alloying elements like Al. Pb, and Mn are influenced by further processing of brass materials such as casting, forming and for customized lengths.
