Our shallow crown heads are particularly suitable for the construction of tanks for containing liquids, such as, for example, underground tanks for diesel oil or tanks for collecting rainwater.
We can make N-type bottoms in both stainless steel and carbon steel, with standard diameters from 500 mm to 2000 mm.
On request we can manufacture parts with thicknesses and heights other than the standard dimensions listed in the table and we can also carry out supplementary machining i.e. drilling, flaring and flanging.
