This plank tested to over 9,000 lb. in an independent third party load test. That’s over 212 lb. per square foot with a 4-1 OSHA safety factor. To be safe the label reads 75 lb. per square foot, but here’s the load test for your peace of mind.
These planks feature zinc-plated bolts with nylon backing nuts rather than rivets, and have wind latches on both ends for safety.
