LaDeau – Where Ethics and Integrity Come Together

Whether it’s our truth-in-selling, our customer care, or our quality of products, LaDeau Manufacturing maintains its standard for excellence, through:

*** Expertise – During WWII, LaDeau’s founding fathers joined the Lockheed Corporation to contribute towards the war effort. At that time, Lockheed manufactured a variety of aircraft, including bombers, nonstop. Today, the Lockheed Martin Corporation remains one of the most renowned defense facilities, on the planet.

The post-war-aircraft industry was ripe for embracing new technologies. It was, then, that our founders launched LaDeau Manufacturing as a sovereign entity which focused on the manufacturing of aircraft hinge assemblies. Fast forward to today – LaDeau Manufacturing serves the large-scale needs of national and global industries, including marine, aerospace, military, industrial, agricultural, commercial and security applications.

*** Quality – ISO compliance means our customers can expect superior quality in every hinge and hinge pin. Our quality-control measures for production parallel our founders’ original commitment to apply stringent MIL-l-45208A standards to all LaDeau parts – military and commercial. As an ISO-9001:2015 certified world-class hinge manufacturer, LaDeau Manufacturing enjoys a 99.8% customer-acceptance rate, as well as being independently certified by a number of aerospace entities.

*** Capabilities – Addressing unconventional detailing, combinations, and configurations is what we love to do! Whatever your hinge customization might entail, you can expect superior strength, alignment, and even-weight distribution. Our hinges are available in steel, stainless steel, stamped aluminum, or extruded aluminum as well as a variety of finishes.
