5. high strength: its strength is ten times as rigid PVC, much higher than the absolute strength of aluminum to achieve the level of ordinary steel;

6. fatigue resistance:

composite covers have some flexibility, which makes the people who work in the above long-term comfort, as a work platform, reducing the staff of the legs and back tension, increase the comfort of working to improve efficiency, human engineering scientists have been recommended;
