Founded in 1961 by José Alonso and Laureno Carus, ALONSO & CARUS iron works, inc., has participated in the construction of hundreds of demanding and challenging projects, including many landmarks of Puerto Rico and the Caribbean region that showcase the superior capabilities of steel.  As the largest integrated structural steel and tank fabricator in Puerto Rico, A&C provides a full range of design, engineering, fabrication and erection services through an innovative, responsive and customer focused organization. 

After being acquired by Euro-American Steel Company in 2006, the present ownership has implemented successful development plans resulting in consistent sales and revenue growth.  This growth has allowed ALONSO & CARUS iron works, inc. to attract more challenging projects and yet maintain the same level of customer satisfaction. 

Today ALONSO & CARUS iron works, inc. is in the vanguard of the structural steel and steel plate fabrication industry.  Our fully integrated engineering, fabrication, field erection and industrial technical services mean A&C is a one-stop solution for all your steel fabrication needs.
