Double garage door lintals
Discussion
Seems like posting a garage build question once a week is my thing now.
Architect has just put in plans for planning permission and is drawing up the building regs plans. The opening is going to be about 4675mm (215mm solid wall) so with 150 bearing on each side the lintal would need to be 4975 so is going to specify a Keystone IBX/K unless I want to use a steel in which case engineers calcs will be required.
A quick look online seems to suggest that the keystone lintal is £1400+. Would it be much cheaper to get the calcs done and use an RSJ? Is it right id need to get a steel plate welded to the bottom to hold the bricks up?

The cost of getting calcs done can be variable.
Also, living where I do, I'd want any RSJ which is even close to the great outdoors to be galvanised.
For a standard job, I'd expect a standard, off the shelf product to work out cheaper.
I've been doing a rough costing for a garage, I was looking at about £600 for a 5m lintel?
What's above your door?
You could look at uklintels.com and compare the numbers for some of their products vs what the architect proposes?
Will it all be solid wall?

Yeah my thoughts were £600-700 for a steel and £2-300 for the calcs which is a fair bit cheaper than £1400+ for the keystone one.Also, living where I do, I'd want any RSJ which is even close to the great outdoors to be galvanised.

Above is the gable end, double skin with no cavity block and breeze.
The Keystone IBX/K is simplistically a steel channel section welded to a wide bottom plate. It’s not a standard lintel for them and that comes at premium.
The cost of engineers calculations and then fabrication of an equivalent will almost certainly work out much cheeper for you, but a lot of people will still go for the more expensive keystone as it’s the easy option and they don’t need to put in the extra work.
