Industrial Hinged Cold Room Doors
The premier choice for heavy-duty cold storage and freezing applications, engineered for maximum climate retention and durability.
General Description
SITC SMART industrial hinged doors are the premier choice for heavy-duty cold storage and freezing applications. Engineered with advanced cam-action locking mechanisms, these doors facilitate rapid opening and closing cycles to preserve internal climate zones. Our standard production size is 90 x 190 cm, with full manufacturing flexibility for custom scales to match any project scope.
Built entirely without wood components, the door leaf is automatically injected with high-density polyurethane insulation between double protective metal sheets. Sealed with specialized commercial EPDM rubber gaskets, these doors eliminate thermal leaks and resist extreme mechanical wear.
