Liangang, a leading domestic steel manufacturer for construction machinery, has partnered with Hunan Zoomlion Intelligent Aerial Work Machinery Co, Ltd, a leading domestic manufacturer of aerial work platforms, to collaborate on the development and application of high-strength, high-quality steel. Liangang’s independently developed LG700QT-GLC, through core technological breakthroughs, has redefined the performance boundaries of aerial work vehicle booms, empowering the Zoomlion ZT82J, the world’s tallest straight-boom aerial work platform, and has earned widespread acclaim.

01 LG700QT-GLC: A Benchmark in Performance

1.Superior mechanical properties: Yield strength ≥700MPa, tensile strength 780-900MPa; more uniform internal structure and properties; high steel purity, 40% increased fatigue life; and improved flatness, enabling greater telescopic travel and higher operating heights.

2.Extreme Environmental Adaptability:Excellent impact toughness at -40°C, with fracture toughness 25% higher than similar materials. No plastic deformation at 1.5 times the rated load, and industry-leading safety margins.

3.A “win-win” for efficiency and environmental protection:Uniform internal stress distribution significantly reduces bending and warping issues in tempered sheet metal. High one-shot forming efficiency meets the demands of automated production lines. Excellent surface quality and low dust levels significantly improve the processing environment. No preheating is required for welding, increasing process efficiency by 30% and reducing lifecycle costs by 20%.

02 Driving Domestic Equipment Globally: LG700QT-GLC

At present, LG700QT-GLC has been applied on a large scale on Zoomlion’s new generation of aerial work platforms, successfully helping customers complete a number of complex working conditions projects, breaking through height bottlenecks, and providing a Chinese solution for the lightweight and intelligent transformation of global aerial work equipment.

From material breakthroughs to industrial upgrades, the collaboration between LY Steel and Zoomlion High-Tech Machinery epitomizes the transition from “Made in China” to “Created in China.” Starting with the LG700QT-GLC, LY Steel will empower high-end equipment with more high-performance steels, injecting strong momentum into “Created in China”!
