What We Do
SOLUTIONS FOR EVERY INDUSTRY
High performance for every size
We manufacture stainless steel tanks in AISI 304, AISI 316, and duplex, as well as carbon steel tanks ranging from 50 liters for the thermohydraulic sector up to 13,000 m³ for the industrial and environmental sectors. These can be single-wall, double-wall, heated, or cooled, using the latest technologies available on the market: plasma and laser cutting, vertical profiling machines, manual, semi-automatic, and fully automatic machines for MAG / TIG / Hybrid Laser welding.
We manufacture small and medium-sized tanks and semi-finished products in our workshops, while the assembly and construction of large-sized tanks take place directly at our clients’ sites, using our own equipment and specialized on-site teams, always ensuring top-quality delivery.
SUSTAINABLE PRODUCTS
Our products are sustainable not only because steel can be infinitely recycled, but also because we are committed to using steel sourced from certified steel mills that adhere to the highest sustainability standards at every stage. This ensures a supply chain with high performance and significant added value for us, our clients, and our environment.
INDUSTRIA 4.0
All our products and solutions can be integrated with various options and automation systems in line with the INDUSTRIA 4.0 incentive plan. In this way, we enable significant process innovations that help transform our clients’ businesses into true smart factories.
