Cold storage hinges
Cold storage hinges are purpose-engineered pivot components designed for sustained performance at sub-zero operating temperatures from −40°C to +80°C — where standard hinges fail due to thermal contraction, lubricant failure, and bearing seizure. HTAN’s cold storage hinge range is manufactured with ISO 9001-certified quality and full OEM/ODM customization for global customers.

Frequently Asked Questions
What is the minimum operating temperature?
Our standard cold storage hinges are rated to −40°C. For ultra-low temperature applications below −40°C, contact us for material and lubrication specification review.
Are food-grade material options available?
Yes. We offer hinges with food-safe surface treatments and FDA-compliant lubricants for food processing and pharmaceutical applications.
How do cold storage hinges differ from standard stainless hinges?
Cold storage hinges use low-temperature-rated lubricants, tighter bearing tolerances to account for thermal contraction, and alloys selected for maintained impact toughness at sub-zero temperatures.
