About Us

Mountain strength.
Sea spirit.

We are a family company founded in 1968 by Bruno Guidi and now led by the second generation.

We design and manufacture marine accessories in bronze, brass, aluminum and stainless steel for engine cooling systems, hydrodynamic systems, generators, air conditioning and desalination systems.

We work for the sea, but our products are born in the mountains, in Grignasco, in the Valsesia valley, where we control the entire supply chain: from raw material selection to the finished product.

Here we design and manufacture more than 4,200 items distributed in over 50 countries, supplying, directly or through distributors, some of the leading Italian and international shipyards.

Every Guidi component is developed in-house, rigorously tested and manufactured with carefully selected materials controlled throughout the entire supply chain.

Our idea of quality is simple: products made to last, with the lowest possible impact and maximum long-term reliability.

We collaborate with universities, research centers and industrial partners to continuously improve materials, performance and corrosion resistance.

We have registered 14 patents and continue to invest in innovation, machinery and training.

55% of our revenue is generated in Italy and 45% abroad.

In 2023 we opened Guidi America Inc., based in Florida, to serve the North American market more closely.

A global company with solid roots.
