S960QL / S960QL1 Ultra-High Strength Steel H-Beams & I-BeamsProfiles S960Q / S960QL

One-stop value-added solution — ultra-high strength H-beams, I-beams and custom structural component fabrication services that fully resolve HAZ softening and pass CTOD tests.

In modern extreme structural engineering, cross-sea bridges, skyscrapers and heavy offshore engineering, reducing structural dead weight and overcoming mechanical space constraints are the core drivers of competitive advantage.
With innovative technology and self-developed hybrid welding technology plus custom profile production lines, Peak Kong Special Steel manufactures high-precision ultra-high strength H-beam and I-beam profiles: S960QL (minimum yield strength ≥960 MPa) and S960QL1 (high toughness at -60°C ultra-low temperature).

Beyond supplying S960QL structural profiles, we focus on adding value to your business. Our full one-stop services cover precision cutting, longitudinal welding, special bevelling and deep machining of high-precision structural components. Supported by our flexible production line, we remove minimum order quantity barriers, helping clients simplify on-site construction work, drastically cut total project costs and shorten lead times!

The welding procedures and fabricated components of this product range have passed stringent CTOD (Crack Tip Opening Displacement) tests and obtained three major welding procedure certifications from SGS, TÜV and DNV. We deliver unmatched safety and commercial compliance for both extreme onshore buildings and deep-sea high-fatigue environments.
