Choosing between horizontal and vertical siding often comes down to visual appeal. Vertical siding offers a unique look, while traditionally horizontal siding has been thought of as easier to install.
With horizontal metal siding, whether you want a traditional or modern look is no longer applicable to the direction you run your panels. With so many panel options, you can now create a unique or modern look by selecting a panel, rather than deciding on the direction it runs.
While wainscot is traditionally run in a vertical pattern, in modern designs we see corrugated metals often run horizontally. This type of wainscot is best combined with a warm material like a natural wood that contrasts well with the cool colors of natural steel. Often used in commercial buildings, horizontal wainscoting also helps to break up long walls where a single siding color or style might appear drab.
