What makes OHSP storage racks stronger than other racks?

​Overhead Storage uses a properly constructed boltless shelving frame. On our Super Duty rack we install 3 center frame supports. Then we bolt on a triple wire grid deck. The deck is supported by all parts of the frame. Other companies that use boltless shelving frames use altered decking and leave out two frame supports. Plus, they don’t bolt the decks to the frame, leaving the structure unstable and weaker.
