As your reference is for aluminium sheet, the word blech becomes redundant as it's "understood". The general accepted term for the exterior covering (facade)on a large modern office/industrial building such as shown in your ref. is "cladding". And cassette is more usually "module" if it does't comprise, say, of a frame with window glass or other complex unit.

So: Aluminium cladding module. Or just Alu. for short if it's going in a list.

Alternative:
\"Aluminium cladding facade\" (one could leave out cassette/module altogether)
or
\"Aluminium panel cladding\" (one could leave out facade- the cladding is a facade)

Point is, Kassette / cassette is really a word more commonly used on the European mainland than in UK or USA- I would avoid re-using it.
