Most commercial wood doors will be either 1 3/8" or 1 3/4" thick and can be solid core or
hollow core. If you are installing the door into a hollow metal frame,
it will almost always be 1 3/4" thick while the 1 3/8" door is usually used in prehung units
which consist of the door already installed in the wood frame with the
hinges. It will be prepped for a lock which will
be installed on the jobsite. Prehungs with 1 3/4" thick doors are very common in commercial
Hollow core wood doors are obviously never used at exterior openings and are usually used
at interior residential although they are also sometimes used on commercial buildings because
of their low price. The majority of prehung units we have supplied over the years have been
solid core since we deal in commercial doors. If the door is going into a hollow metal
frame, it will almost always be a solid core. This type of door is available in either stave
or particle core. Particle core is the most common as it is less expensive than the stave core
which is a solid lumber core door. There has been a lot of improvement with particle core
doors and that is generally what is called for now when solid doors are needed.
Although wood doors are available in many types of veneers, the most common are oak, birch,
hardboard, and medium density overlay (MDO). Oak is good if you are staining the door although
birch is available in a stain grade and is less expensive. Oak doors usually are not painted
as the grain will show through afterwards and if you are going to cover it up with paint, you
might as well go with a cheaper veneer.
We keep a complete stock of wood doors in fire rated and non fire rated. We
have these wood doors in stock machined to match our hollow metal frame hardware locations
and we also have slab wood doors that we can machine to your specifications. We are
fully equipped to machine these wood doors to whatever you may need.
