Ceco’s Long Bay® System is custom-engineered to allow for flexibility in architectural design while accommodating structures needing extended areas of open floor space.
Clear-Span Metal Buildings

Long Bay® System
Ceco’s Long Bay System® utilizes open web truss secondary-framing, delivering roof support and shortening the installation of mechanical and electrical systems. Our clear-span metal buildings compatibility with multiple wall and roofing systems provides you with amplified flexibility in construction design. The Long Bay® System is the perfect solution for manufacturing, warehouse, distribution and large retail applications.
The single-source design, fabrication and schedule control eliminates inconsistencies and interruptions during the entire building design and erection process. The Long Bay® System requires less bridging – no welding or inspections, reduced footings and a fewer number of interior columns. The result is a substantial overall cost savings and an opportunity of speed to market, typically by two to four weeks.
The wide-span metal building is offered in bays up to 60 feet. The Long Bay® System is flexible in the design with less bridging that is attached with self-drilling screws, the ability to bolt to the main frame, and is stiffer and lighter than the bar joist. This open web purlin is fabricated of light-gauge cold-rolled steel with a 4″ chord width and 5″ seat depth.
The Long Bay® System can interface with load-bearing masonry or tilt-wall construction and offers a faster, more precise installation. The Long Bay® System is easy to handle maneuver and erect with no warp or sweep.
