chain resistant to bolt cutting?

Is there much point in using a chain much stronger than the gates themselves? If they can be cut easily?

After the robbery at our place a few weeks ago then it seems nothing will stop a cordless angle grider.

I would be inclined to buy a motorbike lock, they are designed to resist cutting. Any chain can be cut given time, though.

That's probably true. But cable is harder to get through with bolt cutters.

hardened chain

They will just crowbar the gate hinges.

As sold for motorbike security etc. As others have said, the thick ones will resist bolt cutters but not an angle grinder.

Is there an alarm similar to the ones that stick on wondows which detect the sound of breaking glass?

There are youtube videos showing how many seconds it takes to cut various motorcycle chains using bolt cutters. Typically less than 10 seconds.

I forgot..

Well, for a gate I'd expect the chain to be out of reach to bolt cutters being employed as depicted in the video.

Had to laugh when I heard this from someone. Apparently two wrought iron gates into a compound had been chained together where they met, but it seemed that the gates were merely hooked over a series of vertical spindles mounted on the gate posts, and the bad guys had simply lifted one of them off to get in.

No but it makes a heck of a lot of noise, so unless you are out in the middle of nowhere its a bit of a give away.

True and the gates are not that tall, so they could be climbed over. I'm not wanting to make a fortress because as you say, anyone determined could get in, but something as a deterrent to opportunists.

Thanks. It is an interesting video but the bolt cutters look 4' long; not the kind of thing many people have (I hope!). I would hope that if someone was using them on a pavement in broad daylight, someone else might call the police!

My daughter locked her bike to the railings outside a central London hospital where she worked and lost the key. She went home by other means and I went with my car, cut the chain with a large pair of bolt cutters, put the bike in the car and drove away. This was in the middle of the day with many people around and nobody batted an eyelid.

By convention farm gates have the upper pivot inverted so that the gate cannot be lifted off to either gain entry or nick the gate. I'm construction a secure compound for a 3 ton mini digger at the moment where the periphery is a 20 foot square water tank with 6 mm steel plate walls 1 metre high bedded in the concrete base. The entrance will be a steel gate, but both hinge end and catch end will have security chains, as although the upper pivot will be inverted, it is possible to unbolt the gate part of the hinge.

It's just that a decent pair of large bolt cutters (or angle grinder) might well cut through the gate itself. And that is going to cost a lot more to fix than a chain.
