Refrigerated Container Long Hinge

Product Description

A refrigerated container long hinge is a specialized component used in the construction and maintenance of refrigerated shipping containers, also known as reefers. Unlike standard door hinges, these are designed to provide robust and reliable support for the heavy, insulated doors of reefers, ensuring an airtight seal crucial for maintaining precise temperature control during transit.

Here's a detailed description:

Key Features and Characteristics:

• Length: As the name suggests, "long" is a defining characteristic. These hinges are significantly longer than typical door hinges, often extending a substantial portion of the door's height. This extended length provides greater stability and distributes the weight of the heavy door more effectively, reducing stress points and preventing warping or misalignment.

• Material: Typically constructed from durable and corrosion-resistant materials, most commonly:

  • Stainless Steel: Highly preferred due to its excellent resistance to rust and corrosion, which is vital in the humid and often saline environments encountered during sea transport.

  • Galvanized Steel: Offers good corrosion resistance through a zinc coating, providing a more economical alternative to stainless steel.

  • Aluminum Alloys: Sometimes used for lighter weight applications, but less common for heavy-duty reefer doors due to potential for less strength compared to steel.

• Design and Construction:

  • Heavy-Duty Gauge: The metal used is of a thicker gauge than standard hinges to withstand the constant opening and closing of heavy doors and the vibrations experienced during transportation.

  • Multiple Mounting Points: Long hinges feature numerous pre-drilled holes for secure attachment to both the container frame and the door. This multi-point fastening enhances strength and prevents the hinge from pulling away under stress.

  • Pin Design: Often incorporates a robust, often non-removable, stainless steel or hardened steel pin that runs the length of the hinge. This design contributes to the hinge's strength and security. Some designs might use multiple smaller pins for easier replacement if needed.
