S960Q/S960QL/S960QL1 H-section Steel / I-beam, Laser Hybrid Welded Ultra-High Strength Steel Manufacturer

World-Class Research-Grade Structural Steel — Published in Engineering Structures !
S960QL ultra-high strength steel H-beams and I-beam profiles that eliminate HAZ softening and pass CTOD tests.

Backed by robust research capabilities and state-of-the-art manufacturing processes, Peak Kong Special Steel has achieved a historic technological leap using self-developed hybrid welding technology and custom profile production lines. We have successfully resolved the notorious industry challenge of HAZ softening and embrittlement during high-power welding of S960QL steel. Our flexible batch production enables fully customised fabrication with no prohibitive minimum order quantities to support small-batch orders.

This globally leading technological breakthrough and academic finding has been published as a laser hybrid welding research paper in Engineering Structures , the top international journal for civil and structural engineering.
In addition, the welded joints have passed stringent CTOD (Crack Tip Opening Displacement) tests and obtained welding procedure certifications from SGS, TÜV and DNV. We deliver safety assurance, production capacity and cutting-edge technical support for world-class engineering projects worldwide.

Six Core Advantages of S960QL I-Beams and H-Beams
1. Extreme ultra-high strength (ultimate load-bearing capacity).
2. CTOD test certified, providing superior resistance against brittle fracture.
3. HAZ softening fully mitigated to guarantee full-section equal strength.
4. Extreme structural lightweighting delivering substantial economic benefits.
5. Exceeds dimensional limits of hot-rolled profiles with full customisation.

Typical Applications of S960QL H-Beams / I-Beams
Giant bracing members and thick-plate transfer joints for supertall skyscrapers, long-span bridges and large public buildings, premium offshore engineering and heavy offshore wind facilities, ultra-heavy construction machinery, military and special vehicles.
