3x3 Heavy Duty Weldable Butt Hinges
Engineered for superior strength and durability, these 3x3 heavy-duty weldable butt hinges provide a robust pivot point for heavy gates, industrial doors, and equipment. Their weld-on design ensures a permanent, secure connection, making them a reliable choice for demanding fabrication and MRO projects in the Los Angeles area.
- Weldable Low Carbon Steel
- Heavy-Duty Construction
- 3" x 3" Open Dimension
- Application: Gates, Doors, & Equipment
Constructed from high-grade, low-carbon steel, our 3x3 weldable butt hinges are designed for exceptional performance and longevity. The plain, unfinished surface is ideal for creating strong, permanent welds directly to steel frames, gates, or doors without any pre-treatment. This raw material composition allows for seamless integration into fabrication projects, ensuring that the hinge becomes an integral structural component of the final assembly. The heavy-gauge steel provides excellent resistance to bending and wear under high-stress, high-cycle conditions common in industrial environments.
These heavy-duty hinges are indispensable for professional fabricators, welders, and maintenance teams. The weld-on installation is perfect for custom-built security gates, heavy-duty container doors, equipment access panels, and agricultural machinery where standard bolt-on hinges would fail. Their robust design supports significant weight, preventing sagging and ensuring smooth, reliable operation over time. Available from our Los Angeles warehouse, these hinges are a go-to solution for both new construction and critical repair (MRO) applications requiring a permanent, high-strength pivot.

Target Users
Ideal for professional welders, metal fabricators, maintenance technicians, and construction contractors. These users rely on the hinges' strength and weldability for projects that demand a permanent and secure pivot solution.
Finish Options
These hinges are supplied with a plain, unfinished steel surface (mill finish). This allows for clean, strong welds without the need to grind off a pre-existing coating. After installation, the hinges can be primed and painted to match the structure for excellent corrosion resistance.
How to Measure
Hinge size is specified by its height and its full width when open. The "3x3" designation refers to a hinge that is 3 inches high and 3 inches wide when laid flat. When ordering, confirm the required height, open width, and material thickness needed for your specific load requirements.
