to secure something to a concreted in anchor point.
any input greatly appreciated.
Almax or Pragmasis.
Although a cordless grinder will still go through even them.
Does it have to be a chain and padlock? Chunky d-lock pretty hard to attack other than with an angle grinder. Something like a Krytonite New York lock or OnGuard Brute have 16.8mm shackles. Much cheaper options that the top quality chains mentioned above with suitable padlocks.
Olii nails it
Though I'm sure someone will be along in a minute extolling the virtues of some Sold Secure Gold ++ Oxford/Abus PoS
I've a 16mm pragmasis chain. Plenty heavy, expensive but not when compared to what it's securing
£180 for a metre..
12kg per metre in weight though - I don’t think I’d want to be locking a fairly delicate push bike up with that.
If it's going through a ground anchor, then the 22mm and so on will not fit any of them, my ground anchors are pretty much maxed out using the fahgettaboudit 14mm chain, let alone the 22mm one i have.
Best bet would be to measure what you need, then work out the maximum chain width, and then look at the market, apart from size remember difficulty is also key, nothing will survive a sustained angle grinder attack, but you can make it harder for them to attack the chain(s) by how you position/lock them up.
I went with what they actually recommend for push bikes, the 13mm with the squire lock (their roundlocks had sold out). My most expensive bike cost me well under £2000 to build up a few years ago, and they're all well used and perpetually dirty. They recommend 13mm for bikes £1000+, and 16mm for £5000+, but caution against weight.
I have the 13mm and the Roundlock through the Double Doofer. You wouldn't want to drop it on a frame, I'll say that much..!
Genuine question here, will and of the above stand up to a rechargeable angle grinder?
i doubt they would, but that would make a hell of a racket.
16mm is th eminimum to be secure as it cannot be cropped by the boltcropper the neds tool of choice. anything less is hardly worth having - certainly round here were boltcropper are used

I thought as much, cheers ton!
I have a Squire 16mm, purely because it was much cheaper at the time than Pragmasis or Almax, but I'd have trusted any of the three. Bigger chains are available I think from all 3, 16mm is already fairly awkward to live with though.
And Pragmasis's Roundlock, which is an absolutely brilliant wee thing, and cheaper than a good padlock too. I can't absolutely vouch for hte lock mechanism- I do trust Pragmasis- but the design is just really clever, the "pin" of the lock is completely protected by the chain so it's effectively cut-proof (ie, there's no reason to do it because breaking the padlock is harder than breaking the chain. Mission accomplished)

Nah, they're still just metal after all. But it does take a while, and you need to cut the links twice.
The main safety thing there is that even today most expensive bike and motorbike locks are absolute crap, which a thief will break faster than you can find the keys... So while noisy attacks can break pretty much anything, most thieves would rather just find one that's unsecured or can be broken with croppers. Like swimming with sharks.

Have a hunt on YouTube and you'll see some examples. It seems a decent Rechargeable angle grinder will eventually get through pretty much anything, but the bigger chains may end up taking multiple batteries and discs as well as many minutes to cut. (As opposed to a few seconds to snip with bolt cutters on the thinner stuff)
I have a 19mm Almax and its enormous. I use it for locking up motorbikes. I have a big flush concreted ground anchor so it will go through that. I was going to put a ground anchor in my other garage glad someone mentioned about chain fitting, I will check before I fit one 🙂
I have a kryptonite fahgettaboudit chain. They didn’t touch it. They went straight through the frame which is nice soft aluminium.
They went straight through the frame
similar story here with a motorbike, massive chain looped through the frame and into a ground anchor, they cut the frame. No marks at all on the chain, didnt even bother trying.
Minimum your insurance company specifies.
Theres little or no point doing anything else see above!

Exactly this. A mate secured his bike. They tried to steal it but couldn't. But they cut his frame.
Insurance was only for theft and not damage so no payout. He wished they had stolen it!
From my experience I'd rather have 3 cheaper chains and locks than one expensive lock.
An angle grinder will get through anything, best to try and put then off or make it tricky. It probably takes longer moving from one lock to another than it does cutting them.
@ton Where's it for? A shed or internal/external garage?
Flood lights, alarm etc will probably do more to put them off. Also don't post pictures on Strava and social media and check your privicy settings.
A choke chain to a German Shepard or something really noisy!
I would agree with @duncancallum if they are determined they are just going to cut the frame to sell the parts. Much as I would like to stop them, at least if I have satisfied the insurance requirements then I am covered.
