A shed without shelves is like a kitchen without cabinets; you'll get some use out of the space, but not as much as you could otherwise. A storage shed provides a place to store insecticides, lawn and gardening tools, handyman tools and anything else you need for your lawn, garden and home. Shed shelving makes better use of the space inside your shed and gives you more storage options.
Galvanised Steel Shelves
Galvanised steel shelves are sometimes referred to as heavy-duty shelves because the shelves are designed for larger and heavier items. The shelves are durable enough to store large bags of mulch and other heavy items. Shelves of this kind are useful in a storage shed because the shelves can stand up to almost anything you place on them. Look for shelves that are adjustable so you can customise the shelves to accommodate taller objects. Galvanised steel shelf systems typically have three or four shelves, but systems with up to eight shelves are available. Metal and steel shelves of this kind require no additional support, but you do need to watch out for rust, especially if your storage shed leaks.
Plastic storage shelves aren't as sturdy or durable as metal shelves, but they are easy to assemble. The shelves come with multiple flat shelves and end pieces that hold the shelves together. You simply lay the flat pieces down and slide the end pieces into the appropriate holes. Then attach your other shelves and end pieces. When you place the plastic shelves in your storage shed, it's helpful to attach a bracket or a screw from the back of the shelf to the wall. This keeps the shelf from tipping over. Store larger and heavier items on the bottom shelves, as the plastic shelves can buckle.
Plywood Shelving Options
Plywood shelves are shelves that you build yourself. Home Shelving Guide provides information on plans and making shelves from pieces of 2-by-4 wood and plywood. You want the best grade plywood you can afford, preferably an A- or B-grade. This means the boards are free from knotholes and blemishes, which may make the pieces less durable. Consider making your own plywood shelves from concrete blocks and plywood pieces. Lay down two concrete blocks and place a plywood piece on top. Stack the shelves as high as you need, using a single concrete block on either side of the plywood piece.
