The Robertson Long Bay System®: Revolutionizing Steel Building Design

Robertson Building Systems has brought forth a solution that caters to projects demanding large spaces with open floor plans: the patented Long Bay® System (LBS). When it comes to delivering uninterrupted space along with the advantage of a considerable architectural design flexibility, Long Bay stands out.

Understanding the Long Bay System

The LBS relies on the open web truss secondary framing, an ingenious design choice that offers dual benefits. Firstly, it provides strong roof support. Secondly, it considerably reduces the time taken for the installation of mechanical and electrical systems. With compatibility across multiple wall and roofing systems, LBS extends the construction design potential to a significant degree. Furthermore, this system finds perfect application in manufacturing, distribution, and expansive retail sectors.

In a construction world that often encounters unexpected challenges, the unified design, fabrication, and scheduling control of the Long Bay System wipes out inconsistencies and potential delays. It brings a streamlined process to the entire building design and erection phase.

The design intricacies of the LBS present another merit. Instead of the traditional welding, Long Bay purlins are bolted to the rafter. This method slashes the horizontal bridging by a significant 50% as compared to a bar joist. Moreover, instead of welding, horizontal bridging is achieved using self-drilling screws. An added advantage of bolting is the feasibility it offers to the erector. Materials can be connected on-ground and lifted in sections during the installation phase, leading to noticeable labor cost savings. This not only accelerates the project speed but also elevates on-site safety standards.

When it comes to size specifications, the LBS offers flexibility, available in bays ranging from 40’ to 60’. With the system being stiffer and lighter than a traditional bar joist, it easily interfaces with load-bearing masonry or tilt-wall constructions, ensuring a faster, precise installation. The result? A structure that is easy to manage, maneuver, and erect, without the issues of warp or sweep.

Distinctive Features of the Long Bay System

  • Size Range: Offered in bays of 40’ up to 60’.
  • Attachments: Features bolted end seat attachments.
  • Build: Stable and easy clip attachment. It’s stiffer and lighter than traditional bar joists.
  • Composition: Fabricated from light-gauge cold-rolled steel having a 4″ chord width and a seat depth of 5″.
  • Compatibility: Harmonizes with standing seam metal roof systems, B Deck, Built-Up, Single-Ply, and Multi-Ply roofing systems.


Benefits of Using Long Bay System

  • Cost Efficiency: Notable savings from reduced foundation costs and simplified erection.
  • Design Flexibility: Fewer footings and interior columns, compatible with multiple wall and roofing systems.
  • Handling: Effortless to handle, move around, and erect without any warp or sweep.
  • Assembly: Panels use self-drilling screws and have the capability to bolt to the mainframe, eliminating field welding.
  • Applications: Ideal for manufacturing, warehouses, distribution, and expansive retail facilities.
  • Construction Ease: Efficiently interfaces with load-bearing masonry or tilt-wall construction and assures a faster, more precise installation.
