concrete anchors for railings
Hi:
I am in the process of installing vinyl covered aluminum railing on my concret patio. I need to dill 4 holes per steel post and use some sort of (at least) 3/8' type anchor at 2 1/2 to 3 1/2 length. My question is what is the best type: wedge, sleeve, or tapcon. I came across some large (3/8") tapcon bolts at a busy beaver near my home. I have used the tapcon screws to install cabineys in my garage and they seem to hold a lot of weight and they can be removed leaving only a hole to fill if one makes a mistake (which I often do). Are the bolts sufficient for my use or one of the other typs? thx |

thats a bad choice for a railing espically if the concrete is old.
neighbor bpought a alunumum railig for her front porch, it looked nice and wouldnt rust, but wouldnt support a child let alone a adult. worse one day she slipped, the raing broke but not before ruinong the porch, the tapcons held fine the concrete crumbled and broke. fortunately the elderly lady wasnt seriously hurt. shew got a new porch with galvanix=zed steel railings cemented in holes in the concrete. |

Never saw or heard of this technique thx again Don;t know what they are called or where to get them in the US (I assume you are there). See this: http://www.screwfix.com/app/sfd/cat/...00071&ts=56311 Basically, you dill a hole, 3/4 fill or so with special polyester or vinylester resin and ram a length of screw stud in, leaving enough sticking out to hold thing being fixed and add a nut. When set, add thing and do up nut - job done Very very strong and places minimal stresses on the substrate. Quite good on unstable crumbly substrate too - they make special resins if you have very poor concrete/block. HTH Tim (in the UK) |
