KEY BENEFITS

  • Single-source design, fabrication and schedule control eliminates inconsistencies and interruptions during the entire building design and erection process
  • Prefabricated, factory-engineered components minimize steel waste and reduce on-site labor and erection time to help lower total project expenses
  • Optimized interior designs can incorporate overhead cranes, mezzanines, conveyors, and future expansions
  • System designs can accommodate rooftop loading for HVAC and other mechanical equipment

Designed for Open Space

The Long Bay® system creates wide-open interiors with bay spacing of 40 to 60 feet between frames, giving businesses maximum usable floor space and freedom to design interior layouts without obstructive columns. Modular column spacing can vary within the building design to optimize interior flow, while still providing full support for features like overhead cranes, mezzanine floors, conveyor systems, or future expansions. By prioritizing open space, the system not only supports today’s operations but also keeps facilities flexible for tomorrow’s needs.
