GLOSSARY - FINISH
Aluminum Paint - Closely replicates a cleaned aluminum finish with the added benefits of powder coat paint. There is an additional charge for aluminum paint.
Glossy White - A bright white with a very smooth, shiny surface.
Galvanized Finish - Steel with protective zinc coating. Factory cleaned. Closely matches finish of galvanized spiral pipe.
Mill Finish - Raw, no finish. Factory cleaned.
