Gate hinge structural pipe fittings are essential for building strong and reliable swing gates in fences, railings, and DIY projects. They feature a durable hinge design that allows smooth opening and closing while maintaining stability. Manufactured from high-quality materials, these fittings are compatible with gate eye fittings and designed to meet bulk buyers’ needs. With multiple surface finishes and sizes available, they offer long service life and consistent performance in different environments.
A gate hinge structural pipe fitting is a specialized component used to attach and rotate gates within fence, railing, and DIY structural systems. It works as the hinge point that allows a gate to swing smoothly while staying firmly secured to the column or supporting pipe. The hinge ring is slightly larger than the pipe diameter, enabling it to fit around the pipe with ease. It is locked into place using an internal hex screw, ensuring the fitting does not shift once tightened.
This type of fitting is often paired with a gate eye fitting (No. 138). Together, they form a complete hinge system that supports the gate's weight and enables smooth, long-term operation. Typically, two sets are used per gate to ensure balance and strength.
The hinge pin is produced with a fixed diameter to provide consistency and interchangeability between different fittings. By using gate hinge pipe fittings, builders and contractors can create gates that are both functional and durable without welding or complex assembly. Their simple installation, reliable performance, and compatibility with different pipe sizes make them a preferred choice for professional projects, commercial fencing, and customized structures where both strength and flexibility are required.
Gate hinge structural pipe fittings can be produced in cast iron, stainless steel, or aluminum to suit varied strength and environment needs.
Cast iron gate hinge pipe fittings are produced through sand casting, ensuring excellent strength and cost efficiency. They are ideal for bulk supply projects requiring high durability and stability. With proper surface treatment, they resist corrosion and provide long-lasting reliability.
Stainless steel gate hinge pipe fittings are made by investment casting, offering superior corrosion resistance and sleek appearance. They are suitable for outdoor or coastal environments where rust resistance is critical. These fittings are reliable for premium projects that demand both strength and aesthetics.
Aluminum gate hinge pipe fittings are produced by die casting, providing lightweight yet durable solutions. They are easy to install, resistant to natural oxidation, and ideal for applications where reduced weight is beneficial. Aluminum hinges are widely used in DIY and decorative structures.
Various surface treatments ensure gate hinge pipe fittings perform reliably in harsh conditions and meet different installation standards worldwide.
Hot-dip galvanized gate hinge fittings are immersed in molten zinc to create a thick, uniform coating. This treatment provides strong resistance against rust, moisture, and harsh weather conditions, making them suitable for outdoor applications such as fences and gates. The zinc layer ensures the fittings remain durable, long-lasting, and able to withstand continuous exposure to rain and humidity.
Double galvanized fittings receive two protective layers of zinc for improved durability. The additional coating enhances resistance against scratches, chemical exposure, and corrosive environments. They are recommended for demanding outdoor conditions, including industrial fencing, coastal areas, and commercial gates. By offering a more resilient finish, they extend the service life of gate hinge pipe fittings and reduce maintenance requirements for large-scale projects.
Powder-coated fittings are electrostatically sprayed with colored powder and cured under heat, producing a smooth, decorative, and corrosion-resistant surface. This treatment not only improves durability but also allows customization in various Pantone colors. Powder-coated gate hinge fittings are ideal for indoor and decorative structures, as well as outdoor projects requiring enhanced visual appeal alongside reliable mechanical performance and long-term protection.
Pipe outer diameter should match the hinge ring inner diameter.
Surface treatment must meet environment and corrosion resistance requirements.
Compliance with local handrail and safety installation standards.
Gates in fences and railings.
Swing gates in handrail systems.
Rotating structures in DIY pipe systems.
