15、inless steel. The liner bottom shall be formed and braced to support a full complement of fully-loaded bulk milk cans and to withstand, without permanent deflection or distortion, the impact normally associated with the loading operation. The liner bottom shall be connected to the liner walls so tha

16、t no liquid can leak into the insulation. This connection shall be able to withstand the impact of the loading operation. 3.6 Framing. loaded storage compartment, and to house the components of the refrigeration system. The thickness of the framing shall be not less than 12-gauge structural steel sh
