Low camber type N bottoms
Shallow crown heads type N
The particularly low-cambered bottoms are suitable for the construction of tanks for the containment of liquids, such as, for example, underground tanks for diesel or those for collecting rainwater.We can make type N bottoms in both stainless steel and carbon steel, with standard diameters from 500 mm to 2000 mm.Upon request, we can perform thicknesses and heights other than those shown in the table and, furthermore, we can carry out additional drilling, lamination and flanging processes.
