1. Good breaking strength and all steel cold press molding. Manufactured in advanced structure and fabricated with all steel cold pressing, ADTOMALL scaffolding coupler’s strength and toughness exceeding national standards and international standards which completely eliminate the risk of scaffolding collapse due to breakage of old cast iron fasteners.

2. Good anti-slide performance, large fitting area. It ensures that the steel pipe and the steel coupler are in a face to face bonding state with the largest joint area. Overcoming the point or line fit of the old fastener and the steel pipe, and eliminating the hazard of steel pipe slipping. Thus ensuring and improving the overall mechanical performance and safety performance of the scaffolding.

3. Anti-stripping with the new connection. It ensures that the fasteners can be vertically correct and firmly fixed when the steel pipe moves, eliminating the possibility of steel pipe slipping.

4. Rust resistance using passivation treatment. The whole piece is passivated and galvanized with double anti-rust treatment which greatly improved its anti-rust ability. Its life is far longer than the old fastener.

5. Fast and portable with structural optimization. The fastener is light and beautiful, reduce the time of assembly and dis-assembly. Also, reducing the labor intensity.
