Framing Types | Steel and Metal Buildings |
| Clearspan - Rigid Frame, Gable (RCG) |
 |
This
tapered member frame is typically used in clearspan situations from 40 feet to 150
feet. It can be either gable or
single slope. Common roof
slopes of 1/4 to 4 in 12 are
offered.
When large clearspan
areas are required for special
|
 |
| industrial and commercial projects, the Clearspan frame type is typically
the economical choice. The Clearspan can be
used with either cold-form purlins or open web joists. |

Nucor Builder: F.E.D. Corporation
|
This tapered member frame is
typically used in clearspan situations from 40 feet to 150
feet. Common roof slopes of
1/4 to 4 in 12 are offered. When
large clearspan areas are required for special
industrial and commercial
projects, the Clearspan frame |
 |
| type is typically the economical choice. A single slope rigid frame is commonly used on retail centers or as a creative way of adding to an existing structure.
The Clearspan can be used with either cold-form purlins or open web joists. |

individual spans of 40 feet
to 80 feet and building widths from 80
feet to 300 feet plus. |

or open web joists. |

The Lean-to frame joins to and
is supported by a main building
frame. Common spans are
20 feet to 60 feet.
The lean-to differs from the
single slope
in that it must be
supported on the high side by
an adjoining building column. |

straight column rigid frame is designed for maximum efficiency
of interior space. It is suitable for all types of small
