Carport to Brick Garage, Flashing Advice

[want2learn]

As you can see I’ve converted my open 'carport' to a brick 'garage'. Im almost finished (still need to do electrical and box the doors) but i would like advice on what you guys have done for flashing (correct word?). I want to cover where the beams meet the bricks and most likely cover from spout to brickv

<o></o>
A couple of people have vaguely suggested anything can be made up to suit, others have said I’ll need to take the spouting off to fit any flashing.
<o></o>
<o></o>
Is there anything out there that can be fitted to tidy up the sides. The steel beam on one side has a slight bow in it not as bad as the photo looks and I’ve also have gaps where I’ve angle grinded the post out.<o></o>
<o></o>
Any suggestions would be greatly appreciated.
<o></o>
I'll posting a thread soon and more pics of start to finish of how I’ve done it and hopefully to help someone else who's thinking of doing it.<o></o>
cheers

Original Carport


After: Almost Finished, I want to go right around garage to cover the gap.
