A bit dated. But a question. Thanks
Enlarged the picture to show what the question is about.
What are the brown steel sections around and under the roof cable supports?
Are they being used to support the roof cable supports when they eventually get dismantled?
Or are they just different coloured steel sections of the stand for no reason?

My guess is, the secondary steel elements are coated in a basic red oxide coating, which is a robust finish to stop rusting. The primary elements have a grey fireproof on top of the red. Some contractors take a view and coat the lot in the grey, some try get any saving they can and if it means some elements that dont need fire proofed to the same extent end up different. Both can still be painted over aestheticslly if/when needed, that's just the primer 'performance' coating.
