Yes it can be cut to any length
The Versa-Lam column is for structural interior applications. It is not recommended for an exterior application.
The Versa-Lam column is designed for a vertical application.
The Versa -Lam Column can't be exposed to the weather nor can it have any ground contact. This would also include ground contact on a cement floor/piers. Based on your description of your project our product would not be able to be utilized.
Please contact the ProDesk at your local Home Depot. We would need to see a set of plans to determine this if this will work, as we don’t know what type of load this column would be carrying.
There is one piece per box.
