Arrow® floor frame kits are the perfect accessory for your new shed. They provide the galvanized metal framework foundation to add a strong floor if your shed is placed on grass, gravel, or bare earth. The frame will raise the floor above ground level to help with drainage and keep your items clean and dry. Use for metal framing only. To complete your shed floor, attach plywood (not included). The proper plywood to use is 5/8-inch minimum thickness, exterior grade plywood with a waterproof adhesive.
