Long Bay is offered in bays from 40′ to 60′. It is flexible in design with less bridging, can bolt to the main frame and is stiffer and lighter than a traditional bar joist. Long Bay interfaces with loadbearing masonry or tilt-wall construction and offers a faster, more precise installation. It is easy to handle, maneuver and erect with no warp or sweep.

The single-source design, fabrication and schedule control eliminates inconsistencies and interruptions during the entire building design and erection process. Additionally, Long Bay purlins are bolted to the rafter rather than welded, requiring 50% less horizontal bridging than a bar joist. Horizontal bridging is attached with self-drilling screws instead of welding as with a typical bar joist. Bolting also allows the erector to connect materials together on the ground and lift in sections during installation. This produces substantial labor cost savings, improves on-site safety and increases speed to market.

The Long Bay System utilizes open web truss secondary framing, delivering roof support and shortening the installation time for mechanical and electrical systems. Compatible with multiple wall and roofing systems, Long Bay provides you with additional flexibility in construction design. Long Bay is also perfectly suited for manufacturing, distribution and large retail applications.

Robertson’s patented Long Bay® System (LBS) is the ideal solution for wide span steel building projects requiring large areas of space with an open floor plan design, delivering uninterrupted space while allowing for ample architectural design flexibility.

Cost Saving System

• Well-insulated buildings consume less energy, reducing operating costs
• Steel liner panel acts as a diaphragm to reduce the need for structural bracing
• No shut-down required during reroofing so your business can continue uninterrupted

Straightforward Solution

• Simple construction details enable fast installation
• Insulation can help reduce noise transmission
• Interior liner attached to the top of purlins acts as a working platform for ease of installation
• Liner panel on inside of building protects insulation and provides an attractive, durable and clean interior

RTS Design Features

• Accommodates up to R-61 (R28 + R13 + R20) insulation and has a tested U-factor of 0.025 BTU/hr-ft-F (0143 W/m2-K)
• RTS clip designed for minimal through-metal contact
• RTS clips in 4″, 6″, 8″, 10″, and 12″ heights allow selection of desired energy efficiency levels to meet zone standards (to Zone 7 climatic)
• Standing seam and through-fastened panel roof systems available

The Most Efficient Way to Add More R-Value to Your Building

You’ll find RTS enables you to increase the energy efficiency in your building in a quick and easy way. Well-insulated buildings are energy efficient, result in lower operating costs. When reroofing or retrofitting with RTS, shut down of your business is not required so regular operations will not be interrupted during the upgrade.

Exceptional Benefits

The interior liner panel in the RTS system serves as a vapour retarder to protect insulation and attaches to the top of purlins and act as a working platform for ease of installation. Well-insulated roofs increase the energy efficiency of a building while simultaneously reducing noise transmission. On the inside of the building, the liner panel protects insulation and provides an attractive, durable and clean interior.
