In industrial construction and infrastructure, laser cutting technology plays a key role in improving precision. The company uses a 10,000W fibre laser system to cut Q355B high-strength steel plates, achieving cutting tolerances of ±0.5 mm and reducing the loss of material strength caused by conventional thermal cutting to less than 8%. The laser's precise trajectory is transforming structural engineering, enabling the creation of complex 138-bolt plates for skyscrapers and hyperbolic flanges for stabilisers on offshore wind turbine towers.
The 100 mm thick panels are cut with a 20 kW laser beam to form a 30-degree V-shape, creating an ideal welding interface and giving the wind columns an impact resistance of over 80 J.The bent rebar for the stadium's profile columns is shaped and bent after 3D CNC laser cutting, thus eliminating carbon cutting caused by traditional laser cutting methods. A more precise buckling curve (RBS) in seismic buildings with millimetre-smooth transition bends, which are laser-cut into the flanges of I-beams, ensures that seismic energy is directed to the correct displacement position. This cold cutting process enables the same platform to process both 32 mm thick cladding panels for high-rise buildings and 0.5 mm thick pear-shaped profiles for decorative columns in light steel villas, thus bridging the gap between structural rationality and architectural aesthetics.
Laser cutting of spacers combines data and reality:
BIM model automatically resolves coordinates of more than 2,000 bolt holes, while maintaining group hole placement accuracy to ±0.8 mm. Laser cutting of distance elements combines data and reality: the BIM model automatically resolves more than 2 coordinates for more than 000 bolt holes, while maintaining group hole placement accuracy to ±0.8 mm, significantly eliminating manual placement errors; laser engraving of the anti-slip pattern on a 40 mm carbon steel plate and simultaneous completion of engraving of the hoisting company's logo; the same system switches from cutting stainless steel columns with light nitrogen to cutting weatherproof steel with oxygen; each column has a two-dimensional laser code that can be scanned to obtain a Z-axis characteristic of the steel plate, a micrometallographic bevel diagram and three-axis inspection data.
From the compressed struts supporting a 1,400-tonne tank in a nuclear power plant to the carbon fibre and titanium composite beams of a space lift, laser cutting and fabrication systems are opening the door to the unknown with photon-sharp technology. Each laser path offers an interpretation of Newtonian mechanics, while each column elegantly responds to the Earth's gravitational pull. Set against urban landscapes and wild monoliths, these creations reveal the scale of human civilisation in the stillness of steel.
