French Door Hinges - OK or Replace?

[DavoUK]

A total of six hinges on two doors. All the hinges are in this rusted condition. The central plastic cover has broken away from several of the hinges revealing oxidisation.

Would you be concerned enough to be looking to replace these hinges? I've not been able to find them online so far.

Many thanks for this info on the hinge type.

So far, the hinges I've found seem to show that the door edge should be at 90° (for example, this one at Amazon https://www.amazon.co.uk/SFS-Dynamic-Adjustable-Hinge-Screw/dp/B089MF25GV) whereas my door edge is not 90°, see second photo of the hinge from above.
Are there different types of SFS 2D hinges?

Yes there are, the door part is specific to that pvc system or profile, the frame part is generic

This one still isn't quite right so it my be worth emailing the pictures you have to them, good guys these

Both of those do look close. Good idea to email them the pictures to confirm either way. Thanks for the suggestion.
