   Yes, it is.  The little holes are for the mud to lock into the cornerbead, so tape is redundant.  I've seen it both ways, but the majority of sheetrock contractors here don't tape metal cornerbead.

   Well it mostly isnt done but if you are doing it , its a good idea.

   Heres why;

   Un taped corners can stay wet for days preventing finishing .

   Taped corners will be dry in the morning after afternoon taping the the day before .

   Sometimes if the corner is crimped it will show a small crack unless its nailed off properly. So in pre mature cracking tape is good insurance .

   It saves mud and is less costly in material overall .

   On a problem deep corner its the cats meow to deep filling . It will also hold a greater amount of mud in place .

   On high standing metal the tape will camoflouge shiners.

   I tape all metal sides .

   This is why I love this site.  I never thought of taping outside corners, but this makes total sense!  In fact it sounds dumb NOT to do it.

   This has been interesting responces. Mooney, you have the same list that i came up with recently. I've been doing remodel work for over 15 years in Alaska, Oregon and now Washington. the area I'm in now is very rual(north eastern partof the state). Every repair of a corner that i have done has been a corner without tape. In the home repairs i'v done i've never had to repair a corner that was taped,with one exception and that house had 2 pluse inches of setteling. Thanks to everyone that gave input. Jack

   It's seen mostly on commercial and better residential jobs, because it's more durable.

   I always taped my metal beads,for most of the reasons that Mooney mentioned, not redundant at all. Corners don't crack this way.

   Not to many drywallers around here do it, although a sub I use sometimes runs fiberglass tape down his beads, I still prefer paper tape

   Then I found No Coat corners and haven't looked back. Still use USG's paper bead quite a bit, both save time

   I switched to tape-on metal corners awhile back, and much prefer them to nail-on.  I get mud behind the bead, for a more solid corner, and there are no defects caused by the nailing distending the metal.  Mud here is cheap enough that a little more mud is not an economic issue.  Labor is the big cost with drywall finishing here, and I find the tape-on corners go faster than nail-on.

   Haven't tried No Coat corners, but I've seen them advertised.  To be honest,  I'm not sure I grasp the concept.  Could you elaborate a little?  thanks!

   A drywall contractor doing work at our plant used metal corner bead attached with adhesive.  It looked like red contact cement that was spray applied.  I don't know if they sprayed it on or if it came that way.  They said they much preferred that to nailing or screwing.

   I've used the 3M high strength spray adhesive to glue on corner bead. I usually spray both sides, set it in place, and use a corner crimper to drive it home.

   I started doing it with metal studs, and liked the results so much I do it with all the corner bead I set.

   Which isn't all that much anymore.

   I also use 3M Hi-strength 90 to attach corner bead.  I then spray down both side of the bead and put on fiberglass tape.  Mud as usual.  No nails, no crimps.  No cracks!

   I haven't done the fiberglass tape on top of the corner bead.

   I'll try it next time .

   DW guy in ME used to set his corners in Durabond 90

   but all the boss types said it was not ($$$ talikng)

   I will be doing it on ay MY jobs!!!I have no comment...
