The Symbol created by Sergio Bianco is a magnet placed inside a turreted shield and facing upward to attract a star. Magnetic force is associated in a direct way with the raw material of the company: iron.
In this way the product is identical to the star, luminous symbol for orientation and good luck 
coming from a higher dimension. In fact, from a scientific viewpoint, in the final stage of its existence, a star
is mainly made up of iron, an element extracted from meteorites since antiquity.
The horizontal cut across the star recalls the anvil, primordial tool of the blacksmith.
The magnet is placed inside an emblem: the ends of the two poles, distinctive in two colours, are also the merlons of a medieval tower. The tower indicates the region, the circular walls that strike the eyes of visitors
were extolled by Dante in the Divine Comedy: “Monteriggioni crowns its walls with towers”.
The Sardelli logo, custom-made design, brings to mindthe cross section

of a supporting beam in the final letter I.
