The Arrow Floor Frame Kit provides an easy way to construct a raised floor in your shed to keep the contents off the ground. This kit is recommended if you are creating your own base, especially if the base will be dirt, gravel, or grass. It is not needed if you are using an Arrow Sheds Base Kit, though both can be used if desired. This floor frame kit is installed after your shed is completely assembled. The floor beams slot easily into the frame of your shed, providing an ideal framework for finishing with 5/8" exterior-grade plywood. Floor finishing material is not included. This kit is made from steel that undergoes a hot dipped galvanization process providing superior corrosion resistance.
