Above you will see a diagram showing you the standard elevations for a 1:12 to 4:12 pitch building. Pitch refers to the angle of the roof and its rise to the center. 1:12 pitch means 1 inch up for every 12 inches towards the center of the building. For example: On a 50 foot wide 100 foot long building with a 1:12 pitch, the building would have 25 inches of rise. The equation to figure pitch is the width of the building divided by 2, times the pitch. Anything above 4:12 pitch makes the building a custom project.

Framed Openings

X - Bracing

Above you will see an illustration of a framed opening for a window. Most doors and windows made for steel buildings can be installed without a framed opening. However, without the structural support of a framed opening, the door or window may move, leak, have severe wind draft,and becomes much easier to break into. Above you will see an illustration of X-Bracing.X-Bracing helps provide structural support to a steel building. Typically steel buildings require 1 bay on each sidewall and 1 bay on each end wall to be X-Braced. If all bays are being utilized for doors, windows, etc., other ways of bracing may be used. See portal frame (below) and main frame end walls (above)(J).
