Primary Steel Frame Options

For ultimate design flexibility your metal building can be designed to your desired dimensions and requirements. Clear Span and Multi-Span options are available to meet your needs. Other benefits are:

  • Offers the capability for innovative designs and special applications.
  • All frame options can be designed for either bypass or flush wall girts
  • Available with tapered or straight columns.

Clear Span Frame

When you need large open spaces the Clear Span frame is the choice. It can be designed in symmetrical and asymmetrical configurations.

Multi-Span Frame

The Multi-Span frame is available in gable or single slope options. The interior columns provide multiple spans across wider buildings. This can be a more economical option on building widths of 80’ and greater when interior columns are acceptable.

Single Slope Frame

The Single Slope frame is available as clear span or multi-span. This is a flexible solution that offers the roof to slope in one direction. If there are drainage restrictions this can be an excellent option. Facades and parapets can be used to give the appearance that all surrounding walls are the same height.

Lean-To Frame

The Lean-To frame joins to, and is supported by, a main frame column. It is an economical way to extend or expand the square footage of an existing or new building. Leave the walls open to achieve a covered area.

Wall secondary structural are rolled cold-formed zee girts. Girt conditions refer to how the horizontal girts are attached to the exterior columns of your building.

Flush Girt (image needed)Bypass Girt (image needed)

A Flush Girt condition provides maximum floor space as no space is provided between the columns and the exterior panels. A Bypass Girt condition attaches to the outside of the exterior columns and is typically the most economical option.
