A requirement for a fire-rated column assembly in an industrial building is that it must be Labeled with a fire rating. This ensures that the column has been tested and approved to withstand a certain level of fire exposure.

B Non-combustible materials- This is also a requirement for a fire-rated column assembly. It means that the materials used in the assembly must not burn or contribute to the spread of fire.

C: Continuous from floor to underside of roof sheathing- This is also a requirement for a fire-rated column assembly. It means that the column must extend from the floor to the underside of the roof sheathing without any breaks or gaps.

D: Minimum thickness of 50 mm- This is not a requirement for a fire-rated column assembly in an industrial building. The thickness of the column will vary depending on the type of construction and the materials used. While a thicker column may provide more fire resistance, it is not a specific requirement.
