The most significant innovation in portal frame structures in the past half century
A stronger, more elegant and more economical portal frame
Corrugated web + composite flange, redefining the cost-effectiveness of industrial steel structures
Since its invention in 1939, the portal frame has become one of the most classic structural systems in industrial buildings.
It is lightweight, long-spanning, steel-saving, low-cost and fast to build, and is widely adopted in industrial buildings worldwide; however, traditional portal frames also suffer from insufficient stability and torsional resistance.
The Ultra-Resilient Portal Frame is an innovative upgrade built on this foundation.
Torsional resistance improved by over 30 times vs. H-section steel
Thin webs exceeding the height-to-thickness limit are replaced with corrugated webs, achieving full-section shear resistance
Composite flanges are used on the compression-controlled side, with C60 concrete filled inside rectangular steel tubes
With comparable strength capacity, stability capacity is significantly improved
Innovative technology delivers all-round performance gains. Patent No.: 2026103023987
With comparable strength capacity, the Ultra-Resilient Beam exhibits an over 40% increase in stability capacity relative to H-section steel.
Note: The Ultra-Resilient Portal Frame performs especially well in crane beam applications, achieving the triple advantage of higher loads, better torsion and less steel.
