High Steel Structures is the largest fabricator of steel bridge superstructures in North America. The company's 110,000-square-foot expansion to its steel fabrication facility in Williamsport, PA, was planned in response to the market demand for steel that was fueled by TEA-21. The additional production space features a 60,000-square-foot fabrication bay and a 40,000-square-foot freestanding coating facility. The expansion provides the ability to fabricate more complex and larger girders, and more than doubled the plant's capacity.
