Why do USG ceilings out-perform seismic requirements?
Since 1957 Donn suspension systems have set the standard, with the optimal combination of shape, size, steel gauge and connection details to produce the tightest systems available, with the greatest lateral and torsional stiffness. For these reasons, suspension systems from USG are proven to greatly exceed the lateral forces experienced in a seismic event.
