I ordered a few extra heavy duty shelving units and over 24 additional shelf beams to add more shelves. Every package that arrived was heavily damaged. The packaging was weak and items were loose inside. A few pieces of tape and wads of packing paper in one box was all that secured about 25 pounds of metal beams. This lead to bent vertical supports and damage to 25% of the shelf beams. I contacted Global Industrial twice via email, called and left messages, and found their on-line chat to be non functional. I'm very disappointed with this company.
