Double garage lintel double check

[Ab12]

I've a 203x133UB25 beam ready to be installed across a double garage opening, it will have a wall plate fitted and hold one end of the timbers of a flat roof, may also hold the double garage door later

2 questions

1. Is it undersized? Ive been doing some reading and seen people are using 203 x 203 x 46 or 60 in these cases
2. What size padstone is best?

Thanks guys

What did your SE say?

What did your SE say?

He hasn't replied to me for over a week and I can't get in contact with him

Did he specify the 203 × 133 x 25kg U beam?

 

[Ab12]

Yes via the phone in a verbal discussion "I think UB will be okay, a 233*133, let me double check but should be good"; and was meant to return to me with calcs and document, 3 weeks ago. Now radio silence

Alarm bells me thinks.

Ask your BCO?

No BCO. It's a double garage, just under 30m²

You need a 2nd SE then

Without dimensions we can't say for sure but a 203x133 is a pretty chunky beam so I'd not be worying for a garage without BRA; worst case global warmimg is cancelled and you get several feet of snow. Might bend a bit too far then

What is BRA?
I have an opportunity to swap it out for 203 x 203 x 46. Would that be more appropriate?

Put some dimensions up and, if I can work up a bit of enthusiasm, I'll crank up Superbeam and see what the numbers actually say.

What you have to realise is that some SEs specify absurdly big steels for no good reason except that they're too lazy to do their job properly. I was once tasked to redesign a loft conversion where 2.5 tonnes of steel were originally specified (750kg in a single beam). My design used about 40kg, gave much better space and stairs that worked.

Other correspondence states it's 6m wide 5.1m deep, so roof load above beam about 2.5x (0.75+ 0.25) kn/m run??

Will get the proper dimensions shortly, and very much appreciated!

Dimensions above. Ideally also I'd like to have roof joists running front to back across that 5.8m span but I can have them across the 5.25m span (though it would change plans in the visible garden - which is the side of the garage); flat roof, EPDM. May do insulation inside at later date, no plasterboard.
