The wind turbine tower is made of Q345E low-alloy structural steel, which maintains its toughness even in low-temperature environments of -40℃, supporting the stable operation of 100-meter-long wind turbine blades; the photovoltaic support uses hot-dip galvanized steel, which is protected against corrosion by a zinc layer (zinc layer thickness ≥85μm), and has a service life of over 25 years in outdoor environments.
