Supporting Steel

Recommended Posts

Hi

I have just had the steel dropped off for some supporting parts of my house.  There is 10 steel posts going in and will be attached to the foundation and also some beams between them.  The person doing the steel has not painted it and there is some surface rust on it.  Does this matter as most of it will be internal.

 

thanks

If any part of the steel is exposed to the outside The whole steel should be dipped galvanised 

A bit of rust on the internal steel won’t matter

So if some of the steel is a 1 metre below ground and encased in concrete this should be ok as it will be protected from the ground?

It’s normally if the steel is exposed to the elements 

I had all ours hot dipped as 7 of the 11 where required 

Not that expensive and will never corrode

It should say on Your engineers drawing

Red oxide paint isn’t expensive and it would only take you a couple of hours to paint the lot. 5 litres will cover 12-14sqm by brush so you would probably only need one tin and it should be £20 at most. Buy a pack of gloves and some disposable brushes too.

Problem I have is a timing issue ground worker that is doing concrete needs to get it done ASAP as going to another job. for 8 weeks

 

so what I take from this is that if they are encased in concrete from foundation to FFL then I should be OK as they will not be exposed to the earth.

 

is that correct?

We get our galvanized steel picked up and back in 2 days  ( wedge group) others are available  😄 , if you go down this route your steel can be a little rusty but no paint on it .Painted or very rusty steel will need shot blasting  which will be additional  cost.

Paint the ends that are going in the ground then paint the rest when it’s up.

Be real careful with sealed, box section fabrications if having them galvanised. You need gas escape holes in them. 

 

If you don't put them in the galvanisers will. They don't really care where they drill. 

 

You can end up with holes, open to the elements in the top side of your fabrication which then fills up with water!
