Improved treatment is realized with the laminated column. Midwest Manufacturing extends a limited lifetime written
warranty on the treated material used in laminated columns. In addition, more consistent penetration is obtained
by individually treating the materials before lamination. The treated materials are inspected by the Southern Pine
Inspection Bureau, and the treatment retention meets American Wood Preservative Association specications. The
treating process has been proven safe by Bell Laboratories, the United States Department of Agriculture and Forest
Products Laboratory and agricultural departments of leading universities.
SOLID COLUMN ANCHOR / FOUNDATION
All Midwest laminated columns are anchored with treated anchor blocks
which are fastened to the treated bottom of the column at the jobsite.
These anchor blocks help prevent uplift. The columns rest rmly on
precast concrete pads which provide a solid foundation for the building.
The laminated columns may also be anchored to concrete slabs or
foundations using fasteners specically designed for these applications.
STRONG TRUSS TO COLUMN CONNECTION
The positive connection between truss and laminated column provides a
strong junction, and in some cases eliminates the need for knee braces.
The bottom chord of the truss bears directly on the center member of the
laminated column. The truss to column fastening is then determined by
the specic building’s specications.
MANUFACTURED TO CUSTOM SPECIFICATIONS
Midwest laminated columns can be fabricated to any length to match
special sidewall heights. The custom features of fabrication allow the
columns to be designed and manufactured for each individual building’s
specications. The number of plys and dimensions of lumber used is
determined by the building’s design requirements.
UNIFORMITY IN
ASSEMBLY & STRENGTH
Southern Pine Lumber provides an
assembly with more consistent strength
and stiffness characteristics. This is
due to the grains of the laminated wood
running in random directions, versus
a solid post. Midwest laminated col-
umns are stronger than solid posts of
the same grade and species. Quality
controlled factory production creates a
consistently straight laminated column,
thus a straighter walled building.
