Our Activity


In ERSI Group we are dedicated to engineering, supply, processing and on-site assembly of passive reinforcement steel for concrete structures.

We are an international benchmark in the construction sector thanks to our comprehensive solution (Armatek®Constructive System) that improves productivity, quality and safety in the works.

The quality and continuous innovation of our products and services has given us experience and presence all over the world and also in most activities identified with human progress.




BIG PROJECT: Construction system, software and own patents that guarantee the integral efficiency in the construction sector.

DEVELOPMENT COUNTRY: Development and industrial and human consolidation plan in the destination country after the execution of a big project.

STEEL TRADING: Purchase and sale of certified commercial steel.




Over time, we have developed a process model (strategic, business and support) that has allowed us to develop in a structured and organised way:
