Rear Door Steel Hinges with Weld

Description

Rear Door Steel Hinges with Weld (Welded Steel Hinges for Rear Doors) are a type of heavy-duty steel rear door hinge secured via welding, designed for high load-bearing capacity and robust installation, widely suitable for applications such as trailers, trucks, and industrial equipment.
1. Core Features
Material and Strength: Made of high-quality carbon steel/thickened raw steel, with some models reaching a thickness of 1/4 inch, offering high tensile strength and long-term load-bearing resistance to deformation.
Installation Advantage: No pre-drilled screw holes required, directly welded onto the door body and frame to form a permanently secure connection, offering far superior resistance to vibration and loosening compared to standard screw-fixed hinges.
Opening and Closing Performance: Most heavy-duty models can achieve a full 270° opening angle, allowing the rear door to swing completely open and significantly facilitating loading and unloading operations.
2. Typical Application Scenarios
This type of hinge is primarily used for dump trailers, rear doors of box trucks, agricultural equipment, container doors, and industrial heavy-duty door bodies. It is also suitable for custom processing projects, adapting to metal door structures requiring high-reliability connections.
