When it comes to concrete, besides metal anchors like lag shield we have the plastic ones being: wall plug, plastic anchor and ribbed anchor. Is there any other (non-metal) anchor that can be used on concrete?

Plastic anchors are by far the most popular. You get them when buying stuff to hang on the wall.

However in my research it seems that wall plugs (below) are better rated (higher weight support).

While wall plugs are not as or even more popular than plastic anchors if they are better rated? I've never received them in products purchased, it has always been plastic anchors. Personally, it seems to me they would just slip (especially from the ceiling) as they seem to be smooth outside.

I have a project to hang a wood panel to the (concrete) ceiling. I was checking about non-metal anchors because metal anchors wouldn't allow multiple replacements of this panel and also usually requires big holes/damages. I know Tapcon would be the most recommended, but I wouldn't be able to reuse the hole when replacing the panel so it's a no for me. I found these three types listed above, and also read about one with/made of "lead" (if not mistaken).

So, I'm curious as to why one would use plastic anchors when ribbed anchors look to be better, and why use ribbed anchors when wall plugs are rated for heavier stuff.

Like everything, I know there are specific situations. However I could not find when one would not use a wall plug and instead go with a plastic (non-ribbed) anchor.

For hanging stuff on the ceiling, which non-metallic anchor would be the best?

I appreciate any insight on that!

    Many of the anchors in your picture are for drywall and/or hollow walls and won't work on solid concrete. – Mattman944 Nov 5 '20 at 15:01

    If you'll take a wander down the "screw aisle" of your local big-box store, you'll not see any of those (except, perhaps, the lag shield) in the section dedicated to anchoring things into concrete. Pick from among those fasteners. I don't think any of these would do to hang more than streamers from a drywall ceiling. – FreeMan Nov 5 '20 at 15:25

    Notice that in your linked post, only the toggle bolt is listed for ceiling application. Of course, that only works if you have a hollow behind the surface for the toggle to expand into. I don't believe any of these anchors will work for you. You can go ahead and use them, but it's above your head, not mine. – FreeMan Nov 5 '20 at 15:28

    You might want to talk to a local building official about your plans and see what they say. You don't seem to be receptive to the feedback you're receiving about your plans for this ceiling; but a building official isn't just feedback, it's what they'll allow. I think you should be looking at attaching furring strips with tapcon-like fasteners, or doing something more substantial like threaded rod (requiring some tricky concrete work in a ceiling.) I understand why you want to avoid that, but seriously, it's a ceiling. If it falls the consequences will be serious. – Jeff Wheeler Nov 5 '20 at 15:53

    @JeffWheeler your recommendation sounds very much like the answer I gave to his other question. – FreeMan Nov 5 '20 at 16:44

It is risky ,no matter what you use. A concrete floor/road is basically in compression. The bottom of your ceiling is in tension and concrete is generally considered to have no or poor tensile strength. There should be steel rebar in the ceiling , I would verify the presence and amount of rebar before putting holes in the concrete. Each of those anchors works by putting compressive force on the concrete in the concrete ; this compressive ( expansion ) adds to the tensile stress. I would check with local contractors and find out what they do.

I believe you will find that the toggler alligator AF6 or larger are suitable for insertion in concrete and have a rating for both shear and pullout. They can also be reused. https://www.amazon.com/gp/product/B0051IAWM2/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

  • This is very interesting! It looks like a good product, and they even state concrete ceiling as an application. I wonder why everybody else says I should go with stronger hold using metal anchors though. – igorjrr Nov 6 '20 at 2:14
  • I've used only them for years. They work in drywall, brick, and concrete. And they can be removed and patched. – Robert Cline Nov 6 '20 at 15:34
