Unlike our competitors, we allow you to
price all building frame types. Select from Clear-span or Modular
rigid-frame buildings. We allow you the full flexibility to choose

Just about every steel building has at least one framed opening. It is
not unusual for buildings to have several openings. Most openings are
created for an overhead door, but can be used for the installation of
glass fronts or other entries. Most sellers offer "field located" framed
openings, which require cutting and fabricating on the job site. DB
always provides factory-located openings unless your project requires
A clear-span rigid frame offers strength
and economy. Since no interior supports are necessary, this design is
best when you require large areas of clear and uninterrupted space.
Factories, warehouses and agricultural buildings are just a few building
types that may utilize a clear-span frame building. A clear-span design
does have size limitations. As the desired width increases, the frames
will become larger and heavier to carry greater loads across the length
of the frame. At some point the cost will outweigh the benefit. Even so,
clear-span buildings are still effective for buildings as wide as 150'
feet and wider in some cases.
Modular frames use interior columns to
evenly distribute the load; reducing the cost of both the frame and
foundation of extra wide buildings. The economical advantages become
obvious when a building width is about 100' wide or wider. As a result,
almost all buildings 100' wide or wider have interior support columns.
Modular designs are often used for large factories and warehouses.
Single Slope Frames
Single slope frames have high and low
eave heights creating a roof that "slopes" from side to side. To select
a single slope design, you specify one eave height and define the roof
pitch. Single slope designs are frequently used for strip shopping
centers, offices, and RV/Boat storage facilities.
