POST FRAME CONSTRUCTION
Post-frame buildings are pre-engineered wood-frame construction systems. The walls feature laminated columns, also called posts, instead of wood studs, steel framing or concrete masonry. Post-frame buildings have evolved greatly from the early days when agricultural buyers built “pole barns” and “pole sheds.”
Post-frame structures are more quickly erected than other kinds of buildings. Because the larger posts and the interlocking frame can handle greater loads than stud-wall construction, fewer structural materials are needed – which saves on material and installation costs. Post-frame buildings transfer loads to the ground through the posts, which are typically embedded in the ground or surface-mounted to a concrete pier or masonry foundation.
Also, because posts are spaced farther apart than studs, there are fewer interruptions in insulating materials. Post-frame buildings feature an exceptionally large wall cavity for ample insulation, which allows for lowered heating and cooling costs throughout the year.
With its roots in the agricultural market, post-frame is now the construction method of choice for any number of commercial, retail, industrial, residential, religious and public building needs. Due to the nature of its design and many external façade options, post frame may be customized to provide virtually any look.
In addition to new construction, post-frame is also an effective and versatile choice for building additions and remodeling projects.
The strength of the structure starts with its foundation, which in the case of a post-frame building are the laminated columns. The columns carry the weight of the building, providing the “legs” that support and stabilize everything above ground.
Like most building materials, laminated wood columns come in different strengths. It’s important to understand that size alone doesn’t measure the strength of a column; there are several factors involved:
Wick uses only machine stress rated (MSR) lumber that meets a minimum strength requirement for all column lumber material, both in-ground treated and above ground untreated. Wick also utilizes an optimal stitching pattern with a 4 foot overlap and plates when splicing long columns. This construction method, when combined with the machine graded lumber, results in columns that are at least 75% stronger than columns utilizing #1 or #2 visually graded lumber.
