Outdoor privacy screen was an excellent purchase.  The whole screen is made of metal and is very durable.  It’s put together with bolts & nuts.  The company provides an Allen wrench and small wrench.  When attaching it to our cement pad, we used our hammer drill then made 4 holes the same size as the anchor bolts then screwed the expanding bolts into the cement.  Very solid and held up the fence well. The anchor bolts are a must to make the fence safe from falling.  It would not stand upright if not used.  The wind would definitely blow it over.   Looks fantastic.  It’s heavy and well made.   Love the look of it.  The only negative was that it didn’t explain or show you how to put the anchors into cement.  Good thing my husband knew how to do that. The directions were pictures without wording.  The packaging protected the fence well. Quick delivery too.
