It is the preferred choice for compliance in project acceptance, commercial procurement and home improvement.

Galvanized Steel: Made of high-quality anti-rust galvanized steel, it features excellent corrosion resistance and an ultra-long service life.

Ultra-high load-bearing capacity: Designed for dynamic loads. It can safely suspend heavy ceiling fans (typically with a dynamic load up to 70 lbs / approx. 32 kg) or large crystal chandeliers (static load ranging from 90 to 150 lbs), effectively preventing the risk of ceiling falls caused by long-term vibration.
