RAW STEEL -DARK (EVEN BLACK) - Raw Steel is a highly recyclable material that gets reused over and over again. This makes the finish and color vary from piece to piece, to sometimes even black. Left untreated, the Raw Steel will rust and develop a natural patina completely unique to your environment.
RUSTED - The Rusted finish varies in coloring due to the mixture used for the rusting process. This will continue to rust and patina over time. I use all-natural ingredients for rusting, no harsh chemicals.
INDOOR FLAT CLEAR -DARK (EVEN BLACK) - The Indoor Flat Clear finish is an oil-based matte clear coat that makes the steel darker, sometimes even black. This finish will hold up well inside and is easy to clean.
OUTDOOR SILVER - The Outdoor Silver finish is a bright silver powder coat with a slight sparkle. This UV protected finish will protect the steel in the toughest conditions including outside in wet and salty environments. Powder coat is a thick industrial coating that is VOC free and holds up for many years.
OUTDOOR GLOSS CLEAR - The Outdoor Gloss Clear finish is a glossy clear powder coat that makes the steel darker, sometimes even black. This UV protected finish will protect the steel in the toughest conditions including outside in wet and salty environments. Powder coat is a thick industrial coating that is VOC free and holds up for many years.
OUTDOOR FLAT BLACK - The Outdoor Flat Black finish is a matte black powder coat. This UV protected finish will protect the steel in the toughest conditions including outside in wet and salty environments. Powder coat is a thick industrial coating that is VOC free and holds up for many years.
OUTDOOR GLOSS WHITE - The Outdoor Gloss White finish is a glossy white powder coat. This UV protected finish will protect the steel in the toughest conditions including outside in wet and salty environments. Powder coat is a thick industrial coating that is VOC free and holds up for many years.
OUTDOOR GLOSS RED - The Outdoor Gloss Red finish is a glossy, bright red powder coat. This UV protected finish will protect the steel in the toughest conditions including outside in wet and salty environments. Powder coat is a thick industrial coating that is VOC free and holds up for many years.
ALUMINUM - The Aluminum finish is the best option if you want the look of shiny metal or stainless steel on a budget. This finish is rust-proof and weather-proof (great for marine environments) and is lightweight. Aluminum is also a soft metal and scratches easily, so please be careful when opening your package.
ALUMINUM POWDER (GLOSS CLEAR, FLAT BLACK, GLOSS WHITE, GLOSS RED) - These Aluminum powder coat finish options will help prevent chips and scratches and give you more color choices. These UV protected finishes will protect the Aluminum in the toughest conditions and help prevent oxidation over time.
GALVANIZED - Galvanized refers to a process in which steel is coated with a layer of zinc to protect it from corrosion. The appearance of galvanized metal is characterized by a shiny, silver-gray surface. The coating gives the material a distinct metallic luster. Over time, the zinc coating may develop a matte gray patina as it weathers, but the initial appearance is typically bright and reflective.
