Weld On Hinges

Weld-On Hinges – Heavy-Duty Bullet Hinges for Industrial Applications

Product Overview:

Weld-On Hinges, also known as Bullet Hinges, are precision-engineered hardware components designed for use in applications that require strong, compact, and smooth-operating pivot points.  These hinges are ideal for metal fabrication projects where welding is the preferred method of attachment.  Constructed from durable materials such as carbon steel, stainless steel, and aluminum, Weld-On Hinges offer a secure and long-lasting solution for industrial, commercial, and heavy-duty applications.

Product Features:

High-Quality Material Options:

Carbon Steel (Black Oxide or Plain Finish) – Ideal for strength-critical applications.

Stainless Steel (Corrosion-Resistant) – Suitable for outdoor or moisture-exposed environments.

Aluminum (Lightweight and Rustproof) – Perfect for weight-sensitive structures.

Grease Fitting Design:

Many of our Weld-On Hinges come equipped with grease (zerk) fittings for easy maintenance and smooth operation over time.

Precision Machined:

Manufactured with tight tolerances to ensure consistent performance and minimal play during operation.

Removable Pin Options Available:

Some models offer removable pins for easier door or gate removal.

Manufacturing Process:

Our Weld-On Hinges are manufactured using a combination of CNC machining, turning, and precision welding techniques.  The process includes:

Material Selection and Cutting: Raw bars are cut to specified dimensions.

Turning and Boring: CNC machines shape the barrels and drill accurate pivot holes.

Welding and Assembly: Pins are inserted, and grease fittings are welded or pressed in.

Surface Finishing: Final surface treatments include sandblasting, black oxide coating, zinc plating, or polishing depending on the material and intended use.

Applications:

Weld-On Hinges are widely used across various industries, including:

Industrial Gates and Doors

Toolboxes and Equipment Enclosures

Truck and Trailer Lids

Security Doors and Vaults

Marine Equipment and Utility Vehicles

Heavy-Duty Machinery Access Panels
