I think it's spines in the sense of spikes sticking out to reinforce the structure rather than a spinal column, hence the short length.

OK, that does help quite a bit then!

It seems as if the notion of 'spinal column' might work then: possibly some kind of vertical members? Though 300 mm seems rather short...

This is a conversion of barracks into a hotel/student accommodation. I suppose an old brick building.
More context:
b) type de façade pour le bâtiment en extension ;
L’ensemble est réalisé par assemblage de profils en aluminium thermolaqué ou anodisé de chez Schüco (ou équivalent) à rupture de pont thermique, fixé mécaniquement au support maçonné après réglage des aplombs et alignements. Il sera auparavant réalisé un relevé de géomètre du support afin que le positionnement soit parfait.

'spined could make some sense, in the sense of a 'spinal column' — note the dimenion of this part: 60 mm (probably deep) × 300 mm (long?) — sounds like it would have quite a lot of rigidity in the plane of its depth, so some kind of reinforcing element / cross-member could make sense.

We could try guessing what this is about, but it would be quicker if you told us :-) Prefabricated buildings? Roofing?
