Engineered for durability and strength, these 3-1/2" x 2-1/4" weldable butt hinges provide a robust pivot point for heavy-duty gates, doors, and industrial equipment. Constructed from high-quality, weldable steel, they are designed to be permanently welded directly to metal surfaces, ensuring a secure and lasting connection for demanding fabrication projects.

  • Heavy-Duty Weldable Steel
  • Dimensions: 3-1/2" H x 2-1/4" W
  • Application: Gates, Doors & Equipment
  • Installation: Weld-On for Permanent Bond
Overview | Specifications | Applications | Finish Options | How to Measure | Order Checklist

These butt hinges are fabricated from low-carbon steel, a material chosen for its excellent weldability and structural integrity. This composition allows for deep, strong welds using common welding processes like MIG or Stick (SMAW) with standard electrodes such as AWS 6011 or 7018. The plain, unfinished steel surface is ready for preparation and welding right out of the box, providing a reliable foundation for custom metalwork and ensuring a seamless integration into steel frames, gates, and enclosures without compromising material strength.

Ideal for both new fabrication and MRO (Maintenance, Repair, and Operations) tasks, our weldable butt hinges are a staple for metal fabricators and welders in Los Angeles. They are frequently used to construct or repair security gates, heavy-duty container doors, trailer ramps, and custom machinery. Their simple, robust design offers smooth, reliable operation in high-stress environments, making them a preferred choice for commercial and industrial applications where durability and a permanent, tamper-resistant installation are critical.

Specifications

  • Material: Weldable Low-Carbon Steel
  • Standards: Material suitable for welding processes compliant with AWS/ASME standards.
  • Strength/Tensile: Designed for heavy load-bearing applications (load rating varies by installation).
  • Dimensions: 3-1/2" Height x 2-1/4" Open Width
  • Finish: Plain / Unfinished (Ready for welding and painting)
  • Certifications: N/A (Component material is of commercial quality)

Applications

  • Fabrication & Welding: Creating custom steel gates, security doors, fences, and BBQ pits.
  • Industrial Equipment: Building or repairing access panels, machinery guards, and tool chests.
  • Trailers & Automotive: Constructing heavy-duty ramps, tailgates, and custom truck bed doors.
  • Architectural & Ornamental: Integrating into ornamental ironwork, large enclosures, and custom structural elements.

Target Users

This product is essential for professional welders, metal fabricators, MRO technicians, and construction contractors working on custom metal projects that require strong, permanent pivot points. It is a fundamental component for any industrial-grade fabrication shop.

Finish Options

Our weldable butt hinges are supplied with a plain, unfinished steel surface. This allows for immediate welding without the need to grind off a pre-existing coating. After installation, the hinges can be primed and painted with industrial coatings to match the finished project and provide superior corrosion resistance.

How to Measure

To specify the correct hinge, measure the required Height (the dimension parallel to the pin) and the total Open Width (the full dimension from the outer edge of one leaf to the outer edge of the other when the hinge is fully open).

Example: For this product, the specification is '3-1/2" (Height) x 2-1/4" (Open Width) Weldable Butt Hinge'.

Order Checklist

  • Product name and required dimensions (Height x Open Width)
  • Required quantity (sold individually or in bulk)
  • Confirm material: Weldable Steel
  • Add any required welding consumables (electrodes, wire)
  • Add any post-weld primers or paints to your order
  • Specify delivery or will-call pickup requirements
