Types of Trailer Door Hinges
Strap Hinges
Strap hinges are known for their long, flat design, which makes them ideal for heavy doors. They provide substantial support and are commonly used in cargo and utility trailers. These hinges are often designed to withstand significant weight and stress, making them a preferred choice for commercial applications.
Butt Hinges
Butt hinges are characterized by their simple construction, typically consisting of two plates that hinge around a pin. They are most suitable for lighter doors and are widely used in recreational vehicles (RVs) and smaller trailers. Their ease of installation makes them a popular option for DIY enthusiasts.
Continuous Hinges
Continuous hinges, also known as piano hinges, run the entire length of the door, offering even weight distribution. This design helps reduce stress on the hinge and the door, making them perfect for ramp doors and side doors. Their durability and strength make them a favored choice for heavy-duty applications.
Weld-On Hinges
Weld-on hinges are specifically designed to be welded directly onto the trailer frame. This method provides a secure and permanent connection, making them suitable for heavy-duty applications where maximum strength is required. They are often found in industrial trailers or custom-built solutions.
Drop Forged Hinges
Drop forged hinges are constructed from high-strength materials and are ideal for areas that experience high stress, such as tailgate posts. Their robust design makes them extremely durable, ensuring they can withstand the rigors of frequent use, especially in commercial settings.
Flush Mount Hinges
Flush mount hinges are designed to be installed flush with the surface of the trailer, providing a clean and finished look. They are commonly used in enclosed trailers where aesthetics matter, while still offering decent functionality.
How to Choose the Right Trailer Door Hinges
When selecting the right trailer door hinges, consider the following factors:
Weight Capacity
Evaluate the weight of the door and the load it needs to support. Choosing a hinge with the appropriate weight capacity is crucial for proper functionality.
Material
The material of the hinge plays a significant role in its durability. Stainless steel and galvanized options offer resistance to corrosion, which is vital for trailers exposed to weather elements.
Design
Choose a hinge design that fits your trailer’s specific needs. For example, continuous hinges offer better weight distribution, while strap hinges provide robust support for heavy doors.
Installation Method
Consider how the hinges will be installed. Some may require welding, while others are designed for simple screw installation. Make sure you have the necessary tools and skills for the chosen installation method.
Aesthetics
If the appearance of the trailer is important to you, consider flush mount hinges for a streamlined look. Choose finishes that complement the trailer’s overall design.
