What purpose do the girts on a metal building serve?

The girts on a metal building support the metal siding. In technical terms, they transfer the wind load from the siding to the vertical supports. The girts are needed because, even though our metal siding is very strong and durable, it is not rigid enough to span the entire vertical height of a building without buckling in high winds or in the event of an impact. The metal panels need some back-up. Most companies will give you the minimum amount of girts to barely pass the deflection criteria.  Their first one starts at 7’ 6” above grade and then every 6 to 8 ft above that.  You can see and feel the exterior panels deflect in high winds.  Not very comforting to be in.  

Our buildings have more girts, the basic and enhanced models have girts 4’ on center and our ultimate model has girts 2’ on center to provide the least deflection of your walls in the industry.

Yes! All Kentucky Steel buildings come standard with full load trusses at both endwalls. That allows you to open the endwall and attach more bays to continue your free span facility. Want to make the building wider and add offices/classrooms? Perfect we have thought of that as well, attach enclosed sheds on both sides with the same snow and wind loads of the original building!
