door hardware finishes

General Information

There are many common finishes found on builder’s hardware manufactured in the United States. In prior years the letters US typically preceded the older hardware finish designations. Many finish designations currently use the more popular BHMA number equivalent. In the chart below the first column indicates the BHMA number, the second column the old US standard number, and the third column indicates the finish and base metal to which the finish is applied. Base metal differences may cause some finishes with the same name to appear slightly different.
