When planning a commercial or industrial building, structural performance matters. However, flexibility, efficiency, and long-term value matter just as much. That is why PTL Fabricators continues to deliver superior results using Butler Manufacturing’s Widespan™ Structural System.
By combining Butler’s advanced engineering with PTL Fabricators’ hands-on construction expertise, clients gain a smarter building solution from start to finish.
Built for Wide-Open Design Flexibility
The Butler Widespan™ Structural System is designed to span large distances with fewer interior columns. As a result, building owners gain wide-open interiors that support flexible layouts and future growth.
This design works especially well for manufacturing plants, warehouses, athletic facilities, and distribution centers. Moreover, fewer columns allow equipment, vehicles, and people to move freely throughout the space. That flexibility often leads to better workflow and improved productivity.
Strength, Efficiency, and Performance Working Together
Butler engineers the Widespan™ system for strength and durability. At the same time, the system reduces unnecessary steel without sacrificing performance. Because of this balance, buildings achieve excellent load capacity while remaining cost-efficient.
Additionally, the system supports high roof loads and long spans without excessive structural depth. This allows for cleaner rooflines and better integration with mechanical systems. In turn, owners benefit from both performance and aesthetics.

The LRF framing system provides a variable roof slope as low as 1/4:12 to 4:12 for a contemporary exterior profile.
PTL Fabricators Adds Value at Every Stage
While the system itself is impressive, PTL Fabricators elevates the result. From early planning through final installation, PTL takes an active role in ensuring each project succeeds.
For example, PTL’s team works closely with owners, architects, and engineers to align building design with real-world needs. Furthermore, PTL’s project management approach keeps schedules tight and communication clear. As a result, clients experience fewer delays and fewer surprises.
Designed for Speed and Constructability
Another advantage of the Widespan™ Structural System is constructability. Butler designs the system for efficient fabrication and erection. Consequently, projects move faster from foundation to completion.
PTL Fabricators enhances this benefit with experienced crews and proven installation methods. Because the team understands Butler systems inside and out, they can identify issues early and solve them quickly. That efficiency helps control costs while maintaining quality.

The Widespan structural system features acrylic-coated galvanized C/Z structural members for added durability and reduced maintenance costs over the life of the building.
A Long-Term Investment in Performance
Beyond construction, the Widespan™ system delivers long-term value. Its durability reduces maintenance demands over time. In addition, the open-span design supports future expansion or reconfiguration.
PTL Fabricators ensures these long-term benefits remain a priority. By focusing on precision, safety, and quality craftsmanship, PTL delivers buildings that perform well for decades.
A Proven Butler Builder You Can Trust
PTL Fabricators is a recognized Butler Builder with a track record of successful projects. This partnership allows PTL to bring national-level engineering together with local construction expertise. Therefore, clients receive both innovation and accountability.
When paired with Butler’s Widespan™ Structural System, PTL Fabricators delivers more than a building. Instead, clients receive a flexible, efficient, and future-ready facility built to perform.
