We now have BILOBA for external doors, version glass-wall (ref. 8010C) and glass-glass (ref. 8015C).
In addition to the usual hydraulic features, which have made BILOBA famous, these hinges have some important pluses:
1) The inner body is completely anodized (deep oxidation)
2) The new covers made of polished and satin stainless steel make them suitable for outdoor installation, too.
3) No more screws at sight and therefore better hinge appearance.
The special deep oxidation (20 micron) and the coating of the entire surface with covers made of stainless steel AISI 316 showed incredible corrosion resistance, more than 500 hours in acetic acid salt spray (according to UNI ISO 9227 AASS Acetic Acid Salt Spray) without showing any sign of imperfection.
