Supporting equipments above the raised floor greatly increases the difficulty of determining a seismic rating for a data center. Moreover, typical equipment racks can reach 2000 lbs (907 kg) in weight capacity, ensuring heavy floor loading requirements needs significant investment and planning.

Dowseng^® Solutions: Racks are assembled on seismic rack chassis directly, and the chassis are anchored on the concrete slab, so there is little possibility of overturn or collapse of racks in case of earthquakes.

As heavy racks are not put on the raised access floor systems directly, the loading requirements and the seismic requirements of raised access floor systems are much lower, this will save a lot of money on raised access floor investments.
