The Jianxing Guardian is a high-shrinkage aluminum alloy retractable gate launched by Jianxing Company. Thanks to its unique threaded staggered contraction design, it has an extremely high shrinkage ratio. Combined with a large-and-small combination head wheel and wind-resistant auxiliary caster structure, this gate is also very wind-resistant and operates smoothly. In addition, it comes with solar lights, so the gate lights up at night to enhance nighttime safety warnings. Since its launch, it has received high praise from users and has become the top choice for enterprises, schools, residential areas, and public places.
