Clips from the job sites

Three clips from the job near Mullen, Nebraska: frames going up, a standing-seam roof being seamed, and the finished buildings. They play without sound.

https://gdlsteelllc.com/wp-content/uploads/2026/09/steel-frames-going-up-mullen-nebraska.mp4

Frames and purlins up, near Mullen, Nebraska. Roof and wall panels fasten to this steel, so it’s hard to fix once they’re on.

https://gdlsteelllc.com/wp-content/uploads/2026/09/standing-seam-metal-roof-seaming-mullen-nebraska.mp4

Seaming a standing-seam roof, near Mullen, Nebraska. A skipped seam can let in water or lift in wind, so every seam has to be closed.

Roofs and walls on, near Mullen, Nebraska. Where the frame and roof clips lead: stone wainscot and timber-style gables.

Questions

Questions about what’s in the photos

They are the secondary framing of a steel building. Purlins run across the roof between the main frames and carry the roof panels, and girts run along the walls and carry the wall panels. Two photos here show crews on boom lifts fastening girts to the wall frames.

Red iron is trade shorthand for the main steel frames of a pre-engineered building, its columns and rafters. The name comes from the red primer these frames often arrive in, though some manufacturers use gray. The frames go up first, and everything else is fastened to them.

Wainscot is a band along the bottom of the walls, usually a separate run of shorter panels in a different color, with trim where it meets the wall panels above. The Glade Park building in these photos has a black wainscot under white walls.

It has two common meanings. In a shop or garage, a bay usually means a parking space or overhead door, so a three-bay garage holds three vehicles side by side. In the framing, a bay is the space between two main frames, which is how a building’s length is laid out.
