What is the difference between
Our Custom buildings are generally associated with
design-build projects that require special engineering.
Our Pre-Engineered buildings meet design criteria that allows these
buildings to be quoted from our in-house computer software.
There is no difference in quality... The difference is in the speed and
economy in processing and some limitations in size and accessories.
Our Pre-Engineered line is only available in our
standard “gable symmetrical” Rigid Frame Design.
Our Custom Buildings are available in Structural Designs
that range from Rigid Frame, Single Slope, Multi-Story,
Long Bay and Load Bearing Tiltwall.
