Why do floors need to be reinforced when equipped with a ramp?
Doors and floors are the most used and abused parts of a walk in cooler or freezer. Standard floors are designed with a 600-LB load per square foot. That sounds like a lot of load carrying ability until it is considered that a 200-LB load on a two-wheel cart can develop a load of 50-lbs per square inch or 7,200-lbs per square foot. Usually when a ramp is requested, it is assumed that two-wheel carts carrying heavy loads will be used in the walk in. Due to this factor, U.S. Cooler will only provide ramps with reinforced floors.
