As the engineering machinery industry shifts toward lighter and higher-performance equipment, Liansteel’s LG700T-GJ High-strength Steel Plate is emerging as an ideal material choice for aerial work platforms. The product offers outstanding processability, stable shape control, and excellent mechanical properties, supporting the development of safer and more efficient equipment.
The steel plate demonstrates superior flatness, with flatness deviation after cutting controlled within 3mm/2m—far exceeding industry standards. This significantly reduces subsequent straightening procedures and improves processing efficiency by over 20%. In addition, the plate exhibits minimal spring-back (≤1°) during bending and features low carbon equivalent, which reduces welding crack susceptibility and supports automated production lines. With a yield strength of 700 MPa, it enables a 10%–15% weight reduction in boom structures while maintaining structural strength and good low-temperature toughness (impact energy ≥50J at -40°C).
A leading domestic aerial work vehicle manufacturer has adopted the LG700T-GJ High-strength Steel Plate in its new-generation model, achieving shorter production cycles and lower procurement costs. “The plate’s stable shape and precision in bending have exceeded our expectations, contributing to more efficient and reliable manufacturing,” commented the company’s technical lead.
Moving forward, Liansteel continues to innovate in the high-strength steel sector, having launched 1400 MPa grade steel globally and applied 1300 MPa grade domestically in ultra-large equipment. The company is also promoting smart welding compatibility and green manufacturing initiatives to support sustainable industry development.
