The disclosure relates to a novel beam and post/column construction which allows for a variety of decorative trim strips to be installed into grooves which are integrally formed in the outer surfaces of the beams and columns. Additionally, there is provision for selectively increasing the structural load capacity of the beam and column by insertion of one or more strengthening members into grooves located in the inner hollow portions thereof. The disclosure finds particular use in the construction of screened patio and pool enclosures. However, there are many other construction applications where the variable load capacity feature may be advantageously utilized to reduce the inventory normally required by a jobber.
