Metal wall art comes in many various styles and patterns. This kind of art can complement any room and is an especially practical choice for bare walls in hallways or foyers (think large ornamental pieces with hooks, for example).
However, large metal wall art is usually very heavy, so you want to make sure it is hanging safely in order to avoid damaging the walls or the art itself. If you can find the wall studs, go ahead and screw directly into them. That is by far the best and safest way to do it. If you can't find the wall studs, fasteners can be used. Different fasteners have different weight capacities, but you also need to take into account the condition and type of wall you are working with.
Plastic expansion anchors
These come in many different sizes (the larger, the stronger) and have ribbed sides that expand and grip the wall when a screw is inserted. Best for items weighing less than 15 lbs.
Threaded drywall anchors
Available in nylon or metal (metal is by far the superior choice) and look like large screws. It's like having two screws in one. As the name suggests, they are intended for drywall and shouldn't be used for objects that are heavier than 25 lbs.
These really versatile anchors have metal "arms" which expand and hold it securely against the wall when the screw part of the bolt is tightened. They come in several different sizes and the largest ones can handle objects up to 50 lbs. Keep in mind that they permanent, and if you want to remove them, you will end up having to patch the wall.
Toggle bolts, the crÃ¨me de la crÃ¨me of fasteners, are essentially long screws with expandable "wings" at one end. They are the best choice for really heavy objects (like kitchen cabinets) and can hold items up to 300 lbs (as long as the wall itself is up for the job).
Once you've picked your fastener(s), you can get started on hanging the art:
1. Pick a location where you want to hang the piece. You are going to need three points on the wall: one at the center top point of the art piece, and from the center point, mark one point each to the right and left sides. The distance of the center to each end point will be a little bit less than half the width of the art. Make sure all three points are in a straight line with the help of a level.
2. Make sure that there are strong screw eyes on each side of the back frame of your art (and if there are none, add them). Attach a wire going from one screw eye to the other, and wrap the ends of the wire around itself (around the main wire, that is).
3. Insert the fasteners at your points. To avoid any unpleasant surprises later on, follow manufacturer's instructions on how to properly install the anchors or bolts. Once the fastener has been installed in the wall, add your screw, but don't screw it so tight against the wall that there is nothing left to hang your art on. You want to leave a little bit of it sticking out, enough to get the picture wire on.
4. Hang your new wall decor. Check behind to make sure it is safely hung and that the fasteners aren't giving way under the weight of the art.
