Abstract
The present invention provides a stud component of a cleanroom wall system that, in addition to supporting wall panels also supports a door, thereby doing away with the need for a separate, standard doorframe. Thus, the universal nature of the wall and door stud components substantially reduces the material and labor cost associated with acquiring and constructing doorframes in a cleanroom wall system.
