Whitmore Steel

About

WSI is an AISC-certified structural steel fabricator and erector specializing in shop-fabricated, prefabricated steel assemblies that support permanent modular and mission-critical construction. The company partners with general contractors, EPC firms, and modular building manufacturers to deliver repeatable, high-quality structural systems for healthcare, institutional, industrial, and data center projects. WSI’s scope includes the fabrication and erection of equipment skids, structural platforms, pipe rack frames, interstitial framing, and large structural assemblies, all produced under AISC quality control standards. Assemblies are fabricated and trial-fit in the shop, delivered ready for installation, and erected using single-pick, bolt-only field connections to reduce site labor, improve tolerances, and minimize schedule risk. With experience supporting hospital and mission-critical facilities, WSI focuses on permanent modular applications where structural accuracy, constructability, and coordination are critical. The company does not manufacture volumetric modules or pods; instead, WSI serves as a specialty structural partner within modular and off-site delivery models, providing the steel backbone that enables faster, safer, and more predictable construction. WSI’s integrated fabrication and erection capabilities allow the firm to support pilot projects as well as scalable, repeat programs, making it a reliable partner for owners and builders pursuing modular, prefabricated, and industrialized construction strategies.
