The excellent quality of a Deadlift Platform is determined by the quality of the material used to make it. The weight-bearing capacity of a Deadlift Platform depends on the plate holders' height, length and thickness.
Deadlift platforms are made of steel, which is about 6mm thick.
Some platforms have a pin that locks the weight into place as you lift it. Some venues provide a safety barrier to protect your back from contact with the floor.
For a deadlift platform to be considered good, it should be able to support at least 1,000 pounds of weight and have at least one-inch clearance on all sides to ensure the user's safety.
