All our flanges are casted with an aluminium alloy of first melting, guaranteeing an unmatched quality of our products.

All our flanges are polished and can be delivered with oxidation treatment to improve the surface roughness and to reduce darkening of threads directly in contact with the aluminium part.

Our models of flanges can reach from 300 to 1250 mm of diameter:

We also can deliver fixed flanges for half beams made of aluminium or made of steel with zinc plating.
