The basic parameters that define a pre-engineered building are:
Building Width is defined as the distance from outside of eave strut of one sidewall to outside of eave strut of the opposite sidewall. This does not include the width of Lean-To buildings or roof extension:
Building Length is longitudinal length of the building measured from out to out of end wall steel lines.
Building Height is the eave height which is the distance from the bottom of the main frame column base plate to the top outer point of the eave strut. When columns are recessed or elevated from finished floor, eave height is the distance from finished floor level to top of eave strut.
Clear height is the distance from the bottom of the main frame column base plate or finished floor level to the inner point of the eave strut at side.
Roof Slope (x/10) is the angle of the roof with respect to the horizontal. The most common roof slopes are 0.5/10 and 1/10. However any practical roof slope is possible.
End bay length is distance from outside of the outer flange of end wall columns to center line of the first interior frame column.
Interior bay length is distance between the center lines of two adjacent interior main frame columns. The most common bay lengths are 6 m, 7.5 m and 9 m.
