Long Bay® System


Your Wide-Span Building Solution

Our patented Long Bay System (LBS) is custom-engineered to accommodate structures requiring expanded areas of open floor space. With bay spacing of up to 70 feet, LBS allows you to achieve an ideal balance of alignment and functionality for manufacturing, warehousing and countless other open-floor applications.
