The scaffold right angle coupler will be evaluated from three points: the alloy corrosion degree, the roasting process and the mechanical detriments.

The main reason why the coupler will be eroded is that the choice of the lubrication on the alloy metal is not right, so the anti-corrosion property is not

good enough. And then parts of the alloy metal will fall down and some fractures and concaves will occur on the surface of the couplers. And another

reason for this is the working temperature of the machines is too high for the metal to sustain normal operation. The scaffold right angle coupler, from

the point of the coupler thickness, it is far more durable and safer for the works in the scaffolding systems.

The scaffolding couplers will have much higher rigidity, duration, and necessary flexibility. There are also the backing track and the steel track to make

space for the couplers to cogently tie the tubes together.

All together, the scaffolding couplers will help to complete the construction work successfully with the lowest possibilities of any accidents.
