BIRCO cast covers guarantee flexibility in their utilisation and in construction possibilities, above all through enormous load reserves. Black-immersion lacquered spherical cast or galvanised cast, construction length 0.5 m.
The galvanising process sees the metal coated with a zinc layer to protect it from corrosion. BIRCO covers are hot galvanised so that all of the edges and openings are evenly coated and the protection from weathering. Construction length: 0.5 and 1.0 m.
