        The joint strength of metal

             All metal joints are relative to the intensity of the horizontal or vertical pull 100kg purposes, and these tests in the tensile strength speed 1kg/min are at room temperature to 50mm/min speed acting on the object of; The following is with the metal connectors Plastic pipe in bending strength can bear before.
        In this case, the shelf can bear in the fall prior to the maximum external force to 30kg (Room temperature, the downward force of 3kg/min speed, balance applied to the shelf)
