Safety: This product uses steel brackets, which will not shatter even if it encounters destructive loads, and has anti-fall function. Performance indicators such as carrying capacity have been tested by the National Construction Engineering Quality Supervision and Inspection Center and are in compliance with the standards of the Ministry of Construction.
