Plastic shelves different

For exmple, we have one of size for plastic tray 48*35cm. But we have 3 kinds of design for the trays, we have 3 moulds. 

  1. cross bottom


2. the bottom of diamond

透明色 6

3. tray with holes


What's the difference between these three designs?

The biggest difference is load bearing.

The bottom of diamond load bearing more better than the others. 

The bottom of cross load bearing more better than the tray with holes.
