Who we are

3A Steel: A world leader in the production of metal moulds for casting Lego®-like concrete blocks!

3A Steel already produces the familiar orange metal moulds for casting concrete Lego®-like blocks with our “3A Block” brand.

Established in 2008, 3A Steel started its activity by offering laser cutting, bending and robot welding of steel products for our local market and the European union.

In early 2009, 3A Steel began engineering and developing the production of special metal moulds for casting Lego®-like concrete blocks. An innovative metal structure allowing the production of interlocking mobile concrete blocks with different shapes, sizes, wide variety and opportunities for realization of diverse projects.

A new and important milestone in our development was marked at the end of 2021, when, driven by our dynamism and desire for growth, we successfully developed our moulds in inch sizes, allowing us to offer quality metal moulds for concrete blocks on the American market.

All our products are offered under the 3A Block brand and are manufactured in a modern European factory with a production area of 5 000 m2. Our factory is equipped with laser cutting machines, a punching machine and precision bending machines by the German company Trumpf, Fanuc and Yaskawa welding robots, modern system for blasting and effective cleaning and preparation for painting, automated powder coating line by the Swiss company Gema. Our factory offers a complete production process for all products.
