What Structural Steel Works does
Structural Steel Works, Inc. (SSW) is a family-owned private corporation headquartered in San Juan, Puerto Rico, founded in March 1968 by Engineer José Aguayo and now led by a second generation (Juan Carlos Aguayo, President & CEO; Maricarmen Aguayo, VP & CFO). The company self-positions as the Caribbean's leading steel manufacturer, erector, and structural steel service center, operating two divisions: a Construction Division that delivers design-build structural steel fabrication and erection, and a Steel Service Center that distributes steel products with free shipping within Puerto Rico. Operations are run through two subsidiaries — Structural Steel Manufacturing, Inc. (SSM) and SSW Engineering & Construction, LLC (SSWEC).
SSW operates from a 140,000–200,000 square foot manufacturing facility equipped with Tekla 3-D modeling software for structural detailing, Peddinghaus drill lines, welding stations, and shop blasting chambers. The company owns its fleet of cranes, aerial lifts, and welding machines, enabling vertical integration from detailing through erection. It was the first firm in Puerto Rico and the Caribbean to earn AISC certification as a structural steel fabricator (2004) and as an erector (2017), and is one of only two companies outside the U.S. mainland to hold erector certification. The certification portfolio also includes seismic and metal deck endorsements.
The revenue model is project-based and quote-driven, with contracts awarded through competitive bidding by general contractors and developers across commercial, pharmaceutical, healthcare, aviation, hospitality, retail, government, and entertainment sectors. Named customers include Mall of San Juan, District Live!, Walmart, Nordstrom, Plaza del Caribe, AbbVie, Eli Lilly, Amgen, Ryder Hospital, Cancer Center, Rio Mar Beach Resort, LMM Airport, Lufthansa, Caribbean Cinemas, and D-Mac Industries. Beyond custom fabrication, SSW has introduced a pre-engineered buildings product line. Revenue is not disclosed.
