scaffold coupler

swivel clamp Performance characteristics of our couplers: 1.Prevent from breaking- be made of hydraulic-forming steel The raw material of our coupler is high quality mild steel. Both of the toughness and the strengthare higher than both of the national standard and the international standard. Our couplers can eliminate the hazard caused by the iron fasteners because of the substandard material of iron couplers. 2.Prevent from slipping-wide faying surface Our couplers keep the state that the steel pipe can contact the coupler in planeinstead of in point and in line. They also can eliminate the hazard caused by the slipping of the steel pipe. And our couplers guarantee and improve the mechanical property and the safety property of the scaffold. 3. Prevent from deforming-optimized structure The concavo-convex and symmetric structure of our couplers keeps symmetrical balance when the couplers get the stress from all directions and avoids the deformation of the couplers. 4.Prevent from falling off- new link The lid and the base connect with each other directly. The screw, steel pipe and coupler keep vertical with each other firmly and the nut has a slip ring to keep from falling off. 5. Prevent from rust-shielding and galvanizing The whole coupler is processed by shielding and galvanizing. Therefore, our couplers have a strong anti-corrosion ability and can be used longer than the old couplers. 6.Quick and light-particulars and consideration Our couplers are light, beautiful and comfortable so that they can improve the loading speed and reduce the labor intensity.
