Anyone know if there is a recommended length / size / material for these? Might have to place a few shortly and have some decent sturdy angle aluminium (found a flytipped "For Sale" sign!) which will be enough for 2, but I think I will need more, so will need to buy some materials and would like to do as good a job as possible rather than place something that will be dangerous / unuseable in a short period of time.

Would the BMC would be good to ask? If so, who? I dropped a question on email to the general address about a week ago, but got nothing back.

Check out the Bolt Products website, there is a load of info about steaks on there including real life test results.

       damn you predictive text!!

Whoops, my bad Chris, was going to mail you back but got nailed by a virus this week.

We got some made up for the BMC, heavy duty galvanised angle iron with a welded hammer plate on top and a cross piece to keep slings in place. Probably overkill for what you need, but we wanted something that could be hammered into rocky soil, and be very visible (we often have to put them in places where they will be a trip hazard, so big is better)

I'll try and find out the spec's if you need them.

Macsalvors do a 4 foot-ish number with an eye 6" down which are doing a job on at least one cliff on the North Cornish coast. No names no pack drill.
   I saw some very shiny kit a couple of yours ago at a very crappy quarry in the Duchy but either someone stole them or `They` took exception to the clear intrusion on a World Heritage Site.

Thanks for all the info, be good to know what you have Dan. What are your thoughts on using the aluminium already available?

And I'm based in Aberdeen, so shipping a load of iron from Cornwall probably isn't ideal!

Anything that isn't stainless steel is going to corrode to be honest, and thats out of the question on price (and it'll get robbed anyway).

Aluminium will fall apart, it turns into something like onion skin when salt water gets to it. Galvanised steel is a better option. Personally I'd go for the old school approach -  assume it will corrode and make it big.

I'm not in the office till next week, I'll see who made ours for us.

Hank Pasquill was it not?

I did hear it was his engineering firm, yeah, but wasn't certain.

We've been using galvanised scaffolding poles down here at Swanage. Hard work to drive them in, but they are visible and should last 20 years.

There's a load of information on the bolt-products website where he pull-tested a load of different setups, I think 1" galvanised water pipe was deemed to be absolutely fine.

Yeah had a look at that SamT mentioned it above
