Integrity is Who We Are

Welcome to LaDeau Manufacturing – your Home for Hinges! Our company proudly maintains its reputation as a universally-recognized and respected leader in hinge manufacturing and hinge pin fabrication. Our company is backed by its rich history that took root in 1946. It was shortly after the end of WWII when our founders focused on supplying hinge assemblies for the post-war aircraft industry. These innovative entrepreneurs embraced continuous innovation and emerging technological methodologies with open arms. That foresight proved to be prudent, since it allowed LaDeau Manufacturing to successfully expand its role in the world market, fine-tune its capabilities, and dramatically diversify its customer base.

Today, LaDeau Manufacturing manufactures hinges and hinge pins to meet the robust demands of industrial, aerospace, commercial and defense sectors, across the globe. These vital industries continue to rely on LaDeau Manufacturing to provide custom hinges, mil-spec hinges & pins, standard piano and continuous hinges, and much more, to serve very-specialized needs.

LaDeau Manufacturing has leveraged well over 100 years of combined experience to position itself on the world stage, and three foundational attributes remain anchored to form the core of who we are, how we think, and how we operate: 1) we remain acutely aware that our customers are the lifeblood of our company and we treat them accordingly. 2) we manufacture hinge products of the highest caliber, at the most competitive prices and 3) we perform all sales and daily operations with efficiency, transparency, and the utmost integrity – anything less is unacceptable.

In 1946, the founders of LaDeau Manufacturing made the then-unprecedented pledge to apply the strict MIL- l-45208A standard to all LaDeau hinges – both military and indsutrial – and to this day, we hold steadfast to that commitment, though the standards have changed. Couple our commitment to only deliver high-quality hinges, with our current ISO-9001:2015 certification, and you have a company driven by dedicated professionals, who embrace LaDeau's coveted acceptance rate, which exceeds 99.8%.

Preciseness and Efficiency Remain 'Job 1'

Manufacturing quality hinges, and delivering your info. and products with the utmost efficiency should be mutually inclusive in any business, and at LaDeau Manufacturing they most assuredly are! LaDeau's fully-equipped in-house engineering and fabrication department, its vast manufacturing arsenal, and the versatility of its proprietary Universal tooling system make it all happen. After it's all said and done, our customers have consistent, ready access to hinges that are unquestionably more durable and precise than the competition. Additionally, our hinge customers reap the benefits of rapid quoting, shorter lead times, and quick turn around. Whether customers request hinges that are standard/custom, simple/complex, or heavy-duty/miniature, LaDeau's customer-centric mission is to provide unsurpassed quality and superior customer care. We aim to work as an extension of your business.

Selection for a Demanding World Market is Critical

LaDeau's vast capability to manufacture both common and unique types of hinges has been crucial in how we meet the diverse and ever-changing needs and demands of our patrons locally, nationally, and globally. Below is a brief summary of our expansive product line:

*** Aerospace Hinges – Aerospace hinges possess extreme precision with a very high strength-to-weight ratio, and are designed for commercial, military, and aerospace applications. Whether for jet fighters, commercial airliners around the world, or satellites that are out of this world, LaDeau manufactures its aerospace hinges to the absolute and exacting standards demanded by this industry

It is often LaDeau's Mil-Spec hinges and pins – MS20257, MS20001, and MS20253 – that become destined for the unforgiving environments and unique missions associated with aerospace endeavors. Many of our company's clients are aerospace professionals or distributors who approach us with exhaustive quality clauses and critically-technical expectations that, absolutely, must be fully met. We’ve been there before, and we can meet your complex quality demands.

*** Butt Hinges – Butt hinges are the most common and most popular type of hinge, and are available in a vast array of designs. Butt hinges are similar in design to the standard residential door hinge, and typically have close to a handheld profile. From very simple to extremely complex, butt hinges are available in aluminum, stainless steel, or steel; they can be recessed or surface-mounted and can be modified in any imaginable way.

*** Continuous Hinges – Continuous hinges are indispensable for so many applications – from the most basic designs, to those that are highly-precise and customized, to Certified Mil-Spec hinges. Since 1946, millions of feet of LaDeau's continuous hinges have served countless needs. These hinges can vary from 0.008" (0.2mm) thin to 0.186" (4.72mm) thick – available in aluminum, stainless steel, steel, brass, and other specialty metals. Continuous hinges are also often called piano hinges.

*** Custom Hinges – For more than 73 years, LaDeau's custom hinges have served the world's most out-of-the-ordinary requirements. LaDeau's custom hinges have taken on thousands of different types of designs in the form of miniature, piano, and precision hinges, to specialty, industrial, spring-loaded hinges, and more. Local and global markets continue to place their faith in LaDeau's stringent quality-control standards for custom hinges, that result in products that are unquestionably durable and precise.

*** Heavy-Duty Hinges – Heavy-duty hinges are exceptionally strong since they must have the ability to support severe loads and/or perform seamlessly when subjected to shock and extraordinary abuse. Industries such as military, construction, transportation, agriculture, and many others rely on extremely robust heavy-duty hinges to get the job done!

Heavy-duty hinges are available in aluminum, stainless steel, steel, and specialty metals with thicknesses up to 0.375” (9.5mm), pin diameters up to 0.625” (15.9mm), and knuckle lengths as long as 4.00” (102mm). For any specifications beyond these, please contact us for further information.

*** Industrial Hinges – The term 'industrial' is an umbrella label for a non-consumer hinge type that serves the harsh demands of the military, aerospace, medical, marine, agriculture, and other vital arenas. These hinges – which range from continuous/piano to butt hinges to spring-loaded hinges, and others – perform a critical role in applications where hinges' impressive strength and uncompromising endurance are deemed an unconditional pre-requisite.

Industrial hinges are embedded in elevated freeway and railroad viaducts in order to reduce bending stresses; they are included in steel fire doors with 3-hour fire ratings; they are integral components of doors used in neutron (radiation)-shielding, and much more!

*** Mil-Spec Hinges – LaDeau's Mil-Spec hinges include continuous hinges made to MS20257,MS20001, MS35821-MS35831 and A-A-55589 through A-A-55596 specifications*. Stocked hinges of 72" (1828.8mm) length are available in various finishes and materials, and can be manufactured to any length, shorter, or longer, including 144” (3657.6mm) long.

Mil-Spec hinges are the most durable and precise stamped hinge in the world. Their designs are structurally unique and militarily superior, to meet the strictest of demands, as dictated by the U.S. Department of Defense. Mil-Spec hinge performance specifications must perform, seamlessly, within the strict parameters of unique functional requisites, the environments in which the hinges will operate, and interface and interchangeability capabilities. These extraordinary hinges are available to non-defense customers, and at a surprisingly fair price, delivering great value to your organization!

*** Miniature Hinges – Even the smallest of hinges play a huge role to help “make the world go 'round”. The fields of medicine and electronics, for example, depend on LaDeau's capability to manufacture precise, strong, miniature hinges for a myriad of uses. In fact, opening your laptop today, required the use of hinges, which connect the display panel and the base assembly.

LaDeau's miniature hinges include material thickness down to 0.008” (0.2mm), pin diameter as small as 0.020” (0.5mm), and holes of diameter as small as 0.050” (1.3mm). For any specifications beyond these, please contact us. Also, LaDeau Manufacturing offers high-speed production of 0.25” (6.4mm) knuckle continuous designs. All manner of coatings and finishes, forming, and other customizations are always available.

*** Piano Hinges – Our industrial piano hinges are fabricated from the same equipment utilized to manufacture our precise Mil-Spec hinges, and are used extensively by aircraft manufacturers, around the world. For more than 70 years, aircraft manufacturers have placed trusted LaDeau Manufacturing for its Made in USA piano hinges, available in the highest grades of aluminum, stainless steel, and steel, with specialized finishes that can be achieved via zinc plating, paint, and other plating options. Light-weight to heavy-duty piano hinge designs can serve as basic/everyday solutions, or they can be customized to meet the exceptional needs of solar-array panels, space-exploration vehicles, and much more.

*** Precision Hinges – LaDeau's high-precision hinges are used in limitless ways, where exacting precision and heft are demanded – exceptionally-high strength-to-weight ratio is paramount. Precision hinges are superior to standard hinges in terms of unequaled performance in operational and environmental conditions. For example, LaDeau’s precision hinges have been launched into the outer reaches of space, on vehicles that have traversed the Mars landscape, as well as having been embedded in satellites, of all kinds. There are also precision hinges that serve more 'earthly' needs, where virtually every segment of a plane, jet, or helicopter are kept together, via close-tolerance precision hinges. Precision hinges could be dubbed 'unsung heroes' in the vastness of the hinge world.

*** Specialty Hinges – When it comes to motion control, niche applications fully rely on specialty hinges to ensure seamless operation and often, optimized protection. Take, for example, the following: tornado-resistant hinges are designed to remain intact during extreme weather conditions – pocket-pivot hinges are fire-rated for schools, skyscrapers, and hospitals – self-closing hinges, which allow drawers to softly close – or how about energy-transfer hinges, that enable electronic-code access into restricted areas. Whatever the specialty need might be, LaDeau has the specialty-hinge solution to manufacture to your hinges’ requirements!

*** Spring-Loaded Hinges – LaDeau offers spring-loaded hinges, featuring Made In USA springs, sourced from trusted partners, who offer standardized springs, as well as the most complex springs available in, virtually, any material or finish. Spring-loaded hinges allow a door, panel, etc. to remain open or closed, as needed. Modifications and any degree of torque can be achieved for any customized application.

After it's all said and done, it simply cannot be argued that the world's endless operations really do hinge on hinges!
