Can I use a piano (or genie or other heavy equipment) on a Rosco SubFloor?
There are two factors to consider when using heavy items such as a piano or genie lift on any floor. The first is the total weight of the item, the second is how that weight is distributed, (its point load). A typical upright piano weighs about 700-1,000 pounds, and a grand piano 1,000-1,300. A grand piano on three small casters may cause a point load of 400 pounds, over the 375 pounds per square inch which can cause the MDF to fail, and certainly enough to cause permanent damage to the foam pads. The same piano, supported by tri-casters that spread its weight, however, could possibly be used for short periods (hours not days) on the Rosco SubFloor. The key when using a piano or other heavy object is to distribute the weight over the largest possible area. If a piano or other heavy piece of equipment needs to stay in the room and in one position permanently, you may want to use solid blocking under the area where the piece of equipment will be stored, or purchase additional foam pads a
