Concrete heads extinct?

[OldieNewbie]

Are concrete heads no longer used over doors and windows? 
 

it seems that every opening has steel in place where the head would usually be. 
 

why is that?

Some still do 

But most use steel insulated lintels

No. Concrete or uninsulated steel there.

No concretes fine 

 

There’s a 1.3 million pounds house being built near us that has used Concrete Lintels over every opening 

some are 2.8 wide

So there’s no actual rules or regulations on bridging over windows or doors and steel? 
 

its at the discretion of the designer/engineer?

your building regs will tell you. Remember most of the guys here are in GB...

It's the load they need to take. 

 

Steel is defaulted to buy many structural engineers as it's easy to spec and there's suppliers in every town. 

 

I would prefer concrete. 

 

Easier to plaster etc after.
