All of the steel fastener performance characteristics
Resistance to break all the steel plate molding. Excellent hydraulic
For high quality, low carbon steel fastener material strength and toughness than national standards and international standards for material request, is listed to eliminate the old product because of the cast iron material in a substandard fastener fracture caused the collapse accident scaffold.
Sliding optimal surface area is large joint
Ensure the steel tube and a joint state face is listed, and the largest area of joint, overcame in the old buckles and steel tube is a point or line, eliminate the steel pipe joint the hidden trouble of the surge, so as to ensure and improve the overall mechanics performance of the scaffold and safety performance.

Resistance to deformation surface area is large joint
Buckles a bump in the overall structure, which can guarantee the symmetric wing the fastener with each direction when pressure of symmetrical balance, eliminate the fastener happen of deformation possible.
Take off the strong resistance to new connection
Build a listed company, the listed steel straight bolt three vertical can always be right, and firmly have prevent slippery nuts washers, eliminate the steel tube may be slippage.

Strong resistance to rust passivation and galvanizing
Whole after passivation and galvanized double corrosion treatment, its ability to rise greatly, corrosion resistance life far more than old buckles.
Fast light details and thoughtful
Buckles light, beautiful, comfortable, loading and unloading added fast speed, lower labor intensity.
