The most commonly used primary framing systems are shown below. All are shown symmetrical about the ridge line. Framing systems which are unsymmetrical about the ridge line, multi-span and multi-gable framing systems with unequal modules are possible but may require more engineering time.
Building Width: No matter what the primary framing systems used, the building width is defined as the distance from outside of eave strut of one sidewall to the outside of eave strut of the opposite sidewall.
Building length: The distance between the outside flanges of the end-wall is considered the building length. Building length is a combination of several bay lengths.
Building height: Building height is the eave height which usually is the distance from the bottom of the main frame column base plate to the top outer point of the eave strut. Eave heights up to 30mtrs are possible.
Roof slope (x10): This is the angle of the roof with respect to the horizontal. The most common roof slopes are 0.5/10 and 1/10. Any practical roof slope is possible.
