Basic Parameters

  • Building Width.

Distance from the outside of sidewall girt flange to the outside of far side wall girt flange is called building width or steel line.

  • Building Length.

Distance between the both end wall columns or girts (whichever is greater) is called building length.

  • Building Height

Clear Height – From FFL to bottom flange of main frame rafter.
Eave Height – Distance between FFL to the top of outer point of eave purlin.
Ridge Height – Distance between FFL to peak point of the building.

  • Roof Slop

It is horizontal angle of roof. Roof slop can be vary but generally 0.5 : 10 to 1.5 : 10 is used considering the economical and aesthetics.

  • Bay Spacing

It is the distance between two frames (Length wise).

  • Primary Framing.

Main Frames, End Frames and Crane System are called primary frames. These frames designed for full bay loading as backbone of metal building.

  • Secondary Framing.

These frames consist on Purlins and Girts used to support roof and wall sheeting. Secondary framing also used to support the main framing components as bracing to increase their load carrying capacity.

  • Sheeting
