Aluminum siding is available in different styles based on the panel orientation and thickness, the type of coating given to the metal and the patterns, finishes and colors on the coated surface. Aluminum siding comes in different shapes such as ribbed and smooth. Seamless aluminum siding is also available.
The panels of aluminum siding can be horizontally or vertically oriented. Between the two, horizontally oriented panels are more popular as they are more resistant to penetration of moisture. Such panels are installed by snapping the hook of the top panel to the lip of the bottom one.
Aluminum siding is coated with a special polymer, baked-on enamel or vinyl. These coatings protect aluminum from excessive wear. Additionally, vinyl coating renders the aluminum siding resistant to denting and oxidation. However, aluminum siding with vinyl coating is more expensive than other styles.
The enamel and polymer coatings of aluminum siding are available in a range of finishes such as matte, textured, smooth and shiny. Patterns available include wood-grained, smooth, stucco and with treads.
Aluminum siding panels come in different thickness ranging between 0.019 inches and 0.024 inches. Thick aluminum siding panels are preferred in regions that experience hail storms. Panels with a ribbed shape have a thickness ranging between approximately 1/2 inch and 1 1/2 inches.
