Has anyone seen this kind of corrosion/pitting on aluminium window frames?

We’ve noticed this pitting/corrosion across a couple of our aluminium window frames and I’m trying to figure out the best way to restore them.

My suspicion is that it may be from when the house was rendered, possibly the renderer didn’t properly protect/seal the windows and the render has reacted with the aluminium.

Has anyone experienced something similar and successfully restored or refurbished frames like this?

What products/process did you use (e.g. sanding, aluminium restorer, repainting, etc.)?

Would really appreciate any advice or experiences before I go down the wrong path!

Has anyone here installed clear motion glass in a standard CRL channel and Door Patch kit? If so how are you powering the door? The best i can come up with is either drilling a hole through the pivot and coming out that way or drilling a hole through the side of the Patch and having an exposed sleeved wire . Its my company's first time installing clear motion and the architect and contractors are idiots. Im aware clear motion makes their own Patch but we'd need to reorder glass and theres a 5 mo lead time and building turn over is next month

I had the outer pane of a very large villa glass panel replaced, and now there’s a localized distortion/refraction band near one side/edge. It looks like a slight stretching/warping effect.

The video in the post is a reflection from the outside. I've also uploaded one more video from the inside looking out and a picture the contractor took of the whole panel at this link here.

A few details:

• Panel size is about 4700 x 2700 mm
• Double glazed unit
• Build-up is 13.52 mm laminated tempered + 20 mm air spacer + 10 mm tempered
• Installed into the existing aluminum frame
• The distortion is most noticeable looking from inside out, but I can also see it in outside reflections
• Installer says this is normal/expected with large tempered glass
• I’m mainly trying to understand if this is within normal visual tolerance or if it suggests installation stress / pinch / bad seating versus a glass manufacturing issue

For people experienced with glazing / large glass / IGUs:

Does this look normal for a panel this size, or not?

And if not, is it more likely:

1. tempering/roller-wave type distortion in the glass, or
2. stress from installation into the existing frame?

Thanks in advance.

First time dealing with glass installation of any type, so do apologize if this question seems dumb. For context, we recently had a glass company come and install frameless shower tempered glass doors and panels. When I carefully inspected it, I noticed there were some chip damage on a hinge that was connecting the glass door to a glass panel.

The first photo shows the largest chip on the glass door where the hinge is. The second and third photos show smaller chips on the glass panel (not the door) for that same hinge.

From what I've read online, even a small chip at the corner, especially at a high-stress area like the hinge, could lead to issues down the road. But right now I'm getting pushback from the glazier, saying that this is within factory standards. Before I push them too hard on this, I just want to make sure that all of these damages are not within standards for a new glass installation.

Landlord had a cracked window pan replaced. It’s a non-opening window so just a pane of glass in a frame. To replace the glass they of course had to remove the wood frame/bead that was originally around the cracked glass. The new glass has been installed and finished with some kind of sealant compound. I know a bit about building but not glazing. Besides that fact that it looks like shoddy workmanship, is this an acceptable solution?

I’m calling these glazing beads out as being too short leading to poor weather seal besides the aesthetic issues.

Any other thoughts?
