Casting concrete/metal track between outside/inside?

[mrowkoob]

Hello.

I am going to recast the edge at the entrance of my garage because it is tilted incorrectly (water comes in), it is crumbling, and it's old.

I have also installed a larger door in the garage. So the old metal strip that was in the concrete between the outside and inside doesn't fit.

The concrete will need to be cast partly inside the garage and partly outside. Apparently, you should have a metal strip between the outside and inside concrete, so to speak, to prevent temperature differences from causing cracks in the concrete.

Where can I buy such a metal piece, does anyone know? I need one that is 5 meters.

Angle iron and such I usually buy at a scrap yard, though it was a few years ago now, so I'm not sure if environmental legislation has changed anything in scrap handling that makes that impossible.

ask your construction company. they usually have.
the angle irons should have embedded items. if you're lucky, the iron will stay in place, otherwise it will come loose

Angle iron? What should I use it for?

 

[SBH]

you can take a picture of the skena you mean.
do you mean the metal that is in the gate?
they are usually "vinkeljärn"

A long, 5 meter metal rail that was lying right where the gate went down.
To me, is an angle iron a fitting?

okay I understand what you mean. like this? http://www.haraldnyborg.se/images/4034.jpg

Exactly, You don't have a flat bar in the concrete, do you?? That's never been the case with my garages, so I cast in an angle iron that we bought from the scrap dealer.
What SBH links to I usually just call an angle, but of course, it's also an angle iron, though not the kind you embed in the garage floor at the gate
