The side frame and roof truss are spaced 2’ apart, roof truss is built like a house , and then hurricane strapped to the floor. The floor is pressure treated ¾ plywood that is tongue and grooved connected to eliminate gaps between plywood floor seams. The entire shed is hurricane strapped internally from roof, to frame, to floor to ground. The floor sits on pressure treated 2”x 6” floor joist (framing). This floor is designed to hold heavy weight (including cars). All our portable sheds sit on pressure treated skids for easy transport to your home or maybe later relocation when needed. The skids can sit on a concrete slab or sit on solid concrete blocks that we provide as part of our delivery, (most common) so a concrete slab is NOT needed in most cases. We then level shed and install hurricane anchors that we also provide. We use the correct anchor as specified by Florida building codes, depending on where shed is sitting, for example, regular ground, asphalt, or concrete. Our sheds are state approved and inspected in the factory to obtain our state certification for each shed to meet all current Florida building codes. Sheds are pre-fabricated and delivered in one piece so we will need to inspect where the shed will be placed, to assure we have room to do our normal and free delivery, or if needed we can arrange a crane to put shed in place if needed for an additional charge. Our sheds are custom made just for you!
