What is the thickness of reinforcement plates under door hardware?

The thickness of reinforcement plates under door hardware is specified as 3.2mm. This thickness is important for ensuring the durability and security of the door components, as reinforcement plates help distribute stresses and loads that occur when the door is used. A thickness of 3.2mm strikes a balance between providing adequate strength while not unnecessarily adding weight or bulk to the door assembly.

Other thicknesses might not provide the same level of performance; for instance, thinner plates may not adequately withstand the wear and tear of regular use, while thicker plates might add unnecessary weight or complicate installation without offering additional benefits. Thus, the standard of 3.2mm has been established as optimal for this application in dry van setups.
