Scaffolding coupler heat treatment process was strictly carry out the stages of temperature and time. Machining process, in strict accordance with Scaffolding couplers and strict to test plastic Scaffolding couplers and steel bonding surface, in order to make sure the Scaffolding couplers sliding resistance, tensile performance requirements. Scaffolding couplers (except base) must pass a 70 n. m torque testing, inspection, not allowed to damage.

The rectangular Scaffolding couplers, anti-sliding performance when P = 14 kn, delta 2 0.5 mm or less.  Docking Scaffolding coupler tensile performance, when P = 6 kn, delta 2 0.2 mm or less. Sand holes covers an area of more than 10 square millimeter of sand holes don't allow more than one place, and the accumulative area shall not be greater than 40 square millimeter. Scaffolding couplers of adhering sand shall not be more than 100 square millimeters. The scale is not permitted in the surface of the Scaffolding coupler. The rest of the technical requirements for the project comply with the provisions of the GB15831.
Cross Scaffolding couplers features:

1, strong resistance to deformation. Compared with ordinary steel plate stamping Scaffolding couplers, because of the craft that make different, break through the traditional stamping process for material thickness (stamping process can reach 3.5 mm thickness limit, because of my lack of strength in the process of actual use easy deformation) of the limit to 5 mm, completely can be used in the process of deformation, effectively ensure the product's safety and repeated use. Right-angle Scaffolding coupler to ensure Scaffolding coupler in the use of good use performance and use, guarantee the construction of normal use.

2, strong anti-sliding performance. The sliding resistance of Scaffolding coupler to ensure the steel pipe with Scaffolding coupler joint surface state, joint area is large, Scaffolding couplers and overcome the cast iron pipe is point or line defect of joint, eliminates the hidden danger of steel pipe slip.
