It’s All About Integrity

LaDeau Manufacturing’s standard for excellence is based on:

*** Expertise – During WWII, LaDeau’s founding fathers joined the Lockheed Corporation to contribute towards the war effort. It was then that this vital aerospace company manufactured a variety of aircraft, including bombers, where production continued, 24/7. Today, Lockheed represents one of the most vital military facilities in the US.

The manufacturing of post-war aircraft continued, full force, unabated. It was then that LaDeau Manufacturing emerged as a sovereign entity which concentrated on aircraft hinge assemblies. That specialized focus ultimately evolved into products and services which, today serve the large-scale needs of national and global industries, including marine, aerospace, military, industrial, agricultural, commercial and security applications.

*** Quality – ISO compliance means our New Hampshire clientele can expect superior quality in every product LaDeau manufactures. 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-9001:2008 certified world-class hinge manufacturer, LaDeau Manufacturing enjoys a 99.8% consumer-acceptance rate, as well as being independently certified by a number of aerospace entities.

*** Capabilities – Addressing unconventional detailing, combinations and configurations is all in a day’s work. LaDeau’s custom hinges offer superior strength, alignment, and even-weight distribution; and they are available in steel, stainless steel, stamped aluminum, or extruded aluminum as well as a variety of finishes. Our primary and secondary processes range from press brake forming to welding to plating and so much more.

At LaDeau Manufacturing, we like to think we help to make the world ‘go round’; and in a very real sense, we do! Without hinges, the world would become unhinged! We will never compromise the quality of our products nor our dedication to customer care. In the end, it all translates into comprehensively meeting the needs of an expansive, global consumer-base; and that will not change.
