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.
Satin Anodized - Satin anodized aluminum extrusions are best described as a polished aluminum look. Factory cleaned. Available on products where noted. Additional charges apply.
Standard Colors (Powder Coat Paint) - Shoemaker uses a baked on textured polyester powder coat paint with a rust-resistant prohibitive pre-coat. Powder coat paint is an extremely durable finish and holds up well to the stress of shipping, installation, general wear and aging. This finish resists the peeling, cracking, chipping, fading and other problems associated with e-dip and other painting methods.
