Sierra Pacific Engineering and Products manufactures weld-on hinges—also known as barrel hinges or bullet hinges—for heavy duty doors and gates on trucks and trailers.

A weld-on hinge is mounted with a weld instead of fasteners, making it extremely strong and able to support a lot of weight. These hinges are useful on thick metal surfaces where it may be impractical to drill and tap holes, and they offer better alignment, while preventing give from side to side.

Many of our hinges are designed with an extended weld guide, which helps to align the rounded hinge on a flat surface—normally a tricky operation. Once the part is aligned, the hinge can be welded in place just like a standard barrel hinge.

Some SPEP hinges come with welded-on brackets or “open wings,” to make mounting and operation in different configurations practical and more efficient. We also offer a three-piece hinge for supporting extremely heavy loads. Some of our weld-on hinges come with a built-in grease fitting for easy lubrication, in order to prevent corrosion, increase part life and allow smoother operation.

Sierra Pacific manufactures weld-on hinges in aluminum, stainless steel and steel in a variety of sizes and finishes, and with bushings made of brass or stainless steel. Our hinge pins come in aluminum, brass, stainless steel or steel, in both fixed and removable pin styles. Removable pin weld-on hinges can be used as “lift-off” hinges for removable doors or gates.

At SPEP we take great pride in the quality of all of our products, and our ISO 9001 certification demonstrates a commitment to quality throughout our organization. As a 100% ESOP company each employee stands behind our products, personally ensuring customer satisfaction. Contact us today to order high-quality weld-on hinges for your OEM products.
