Engineered Structural Sections

Thermatool is the global leading brand of custom beam section HF Welding lines.

Patented in 1970, Thermatool™ Engineered Structural Section Lines have been field proven again and again for structural HF Welded beam production. With the advent of new steel chemistries and improved flat rolled steel technologies, HF Welded Engineered Structural Section production is meeting ever-growing infrastructure demands by providing innovative engineered solutions to structural design problems. An alternative to hot-rolled standard structural I and H beams is now available to architects and engineers intent on creating innovative designs by using different strength materials in web and flanges of beams to save weight and improve load-carrying strength. Along with the ability to use different materials, asymmetric structural geometries can be designed for specific applications. Thermatool™ Engineered Structural Section Lines can then produce HF Welded sections cost effectively and in volumes consistent with custom design requirements.

The HF forge weld, proven to be the strongest weld available, is accomplished through Thermatool™ HF Solid State Contact Welders. The combination of selecting the right power and frequency gives structural sections producers the ability to successfully weld different materials including Aluminum, Carbon Steel, Stainless Steel, Advanced High Strength Steel and even Weathering Steels.
