Stainless Steel Unistrut

Within Unistrut's special metals category lies not only stainless steel st, but also aluminum. Most fittings and channels shown in the Unistrut catalog, are available in aluminum or stainless steel - though there may be a manufacturing lead time associated with some of the lesser sold items.

However, these two items should not necessary be used together.

Becuase they have a dissimilar galvanic potential, galvanic corrosion can occur when they come into contact with one another. Galvanic corrosion (aka bimetallic corrosion or dissimilar metal corrosion) is an electrochemical process in which one metal corrodes when it is in electrical contact with another, in the presence of an electrolyte.

The best way to avoid galvanic corrosion is not to pair these two metals together. But, if you do need to use them together, their are a few ways to curb galvanic corrosion:

• Applying coating or paint can act as a barrier
• The use of a gasket or other barrier layer between the two metals can inhibit corrosion
• Use of a third, sacrificial metal between them allows that metal to corrode first and preserve the other two metals
