This is a very advanced and highly competitive processing technology and engineering solution. For 30mm S960QL ultra-high strength structural steel, the successful application of “laser composite welding” in mass production, simultaneously meeting EU, Japanese, US, and British standards, effectively solves the industry pain point of traditional welding easily leading to material weakening and deformation.
We can help you efficiently connect directly with target clients (such as owners, consulting firms, and heavy machinery manufacturers) who have engineering project needs or require technical solutions consultation:


Extreme Weight Reduction Replacing the traditional S355 with S960QL can significantly reduce the structural weight by 40% – 50%, directly reducing infrastructure costs and transportation and hoisting expenses.
Quality Commitment Possesses HOKLAS-accredited PF/PC welding process certification, fully compliant with government and international large-scale engineering compliance reviews. 【Multi-International Standards】: Seamless butt joints meet standards such as EN 10025-6/EN15614-11/EN15614-12/AWS D1.2/AWS D1.6, suitable for both local public works projects and overseas engineering projects.
Crane telescopic booms, crawler crane gantry booms, port quay cranes (high requirements for lightweight and fatigue resistance).
Large-span building and bridge engineering: skyscraper conversion trusses, large-span steel box girders, high-load-bearing special steel structures (requiring high seismic resistance and high yield strength).
High-end public infrastructure construction: such as airport terminals, stadium roofs, etc., requiring modern structures that balance aesthetics, slender lines, and ultra-high load-bearing capacity.
Offshore platforms and near-shore platform wind power facilities.


Channels (UPN/UPE)
Equal/Unequal Angles
Hollow structural profiles (square tubes/flat tubes/box beams).
Length and Tolerances: Length requirements for individual profiles, and whether there are any special geometric tolerance limitations exceeding international standards.
Delivery Standards: The relevant standards for this project (EU EN, US ASTM, UK BS, Japanese Standards).
Flaw Detection and Certification Requirements: Whether an EN 10204 3.1 certificate or a radiographic/ultrasound (RT/UT) non-destructive testing report of a specific scale is required.
