Steel Trusses Every Fabricator Should Know How to Make
A truss is an assemblage of steel beams that are fabricated so that force is applied to only two points. Steel trusses are used in nearly every type of construction project, including skyscrapers, arenas, and bridges. Structural steel fabricators who want to be known as the best in the industry need to be able to make perfect trusses. They should also be aware of the many different types of trusses that are used in construction. These include:
North-light trusses are strong enough to span 20 to 30 meters, making them ideal for large spaces where natural light and ventilation are required. As one of the oldest types of trusses in the industry, a north-light truss is a reliable choice for professional builders and architects.
The steel beams of a warren trust are assembled diagonally to form a “W” shape. The repeating equilateral triangles comprising the “W” shapes offer superior weight balance, allowing warren trusses to span up to 100 meters.
King Post Trusses
Featuring two force-supporting beams and a single vertical post, a king post truss is one of the easiest to fabricate. King post trusses are common in smaller buildings and sub-assemblies of larger structures.
Queen Post Trusses
Similar to king post trusses but featuring two vertical posts, queen post trusses are stronger and more versatile. Though also intended for smaller structures, queen post trusses can support larger spans than king post trusses.
Fink trusses are easily identified by multiple diagonal beams that extend down from the end post to the bottom of the vertical post and are most commonly used in constructing bridges. Though they were popular in the past, Fink trusses are less common in the industry today.
Often used in bridge building, Howe trusses feature vertical beams that are in tension and diagonal beams that are in compression. This strong design allows Howe trusses to span up to 30 meters.
The design of a Pratt truss is opposite that of a Howe truss: The vertical beams are in compression and the diagonal beams are in tension. This results in a stronger assemblage that can handle lengthy spans of up to 100 meters.
How to Fabricate Perfect Trusses
If you’re a professional structural steel fabricator and looking to improve your production of steel trusses, you’ll want to know about BeamCut, the industry’s leading robotic plasma cutting technology. This remarkable system was designed with state-of-the-art features to help your business get ahead in a crowded field of talented fabricators. These features include:
The six-axis FANUC robotic arm can bevel 360 degrees, making short work of any shape or profile needed for truss assemblies. And it’s three times stronger and lasts three times longer than the industry standard.
BeamCut features the latest X-Definition plasma from Hypertherm, one of the most powerful fuel sources available.
User-Friendly CNC Software
Manually calibrate cutting tolerances, nest parts, and track robotic cut paths to eliminate mistakes on BeamCut’s easy-to-use interface.
Benefits of BeamCut
BeamCut can handle every step of the fabrication in one pass, and it’s fully automated. Equipped with this revolutionary CNC plasma cutting technology, you can eliminate waste, maintain a lean workforce, and reduce your production time by as much as 80%. That’s a substantial return on investment!
