Brass is a "classic" product used both inside and outside (dependant on the quality of brass used). Brass can be engraved and paint filled any colour to meet your specific requirements
We personally recommend that brass is used both inside rather than outside as it is susceptible to vandalism and wear and tear including tarnishing, pitting and scratching. Ifused outside the in-filled paint will eventually come away.
Brass can be highly polished if required however it requires regular polishing to retain its shiny finish and can be problematic if not maintained
