Brass plaques have a slightly paler initial appearance than bronze, and are suitable for use in areas where serious vandalism is not anticipated. Brass plaques tarnish quickly, and can acquire a green residue. They are not suitable for use on European oak boards, which will cause the edges of the plaque to tarnish rapidly.
On steel boarded seats these plaques are surface mounted and secured by stainless steel button head screws.
Any length of inscription is possible with these plaques, though at more than 200 characters, the inscription becomes harder to read.
