the racking that fall down is not the GETC company ,it is another company that make supermarket racking . Because the load capacity of supermarket racking is not big ,this type company will use thin material ,for the box beam ,the thickness of our compay is 1.5mm ,but many small company will choose 1.45mm even 1.4mm in order to save the cost ,but the safety is a big problem .
You can explain this to the customer .
