HIGH-PERFORMANCE COMPOSITE PRODUCTS SINCE 1945

The Gill Corporation was founded on September 11, 1945 by a man who believed that "plastics" was the future - Merwyn "M.C." Gill. He started the company in a garage in Montebello and, today, it is the oldest, continuously operating manufacturer of advanced composites for the aviation industry in the world.

The company's original market was consumer products such as laminated place mats, lamp shades, plastic wall coverings and balsa bat and cork ball baseball games which were popular in the post-war era. But, after seven years of struggling, an opportunity emerged to manufacture belly baggage compartment wall linings for Douglas Aircraft's DC-6. The company developed light-weight, high-strength, corrosion-resistant Gilliner®1066 for the application and became a principal supplier to Douglas Aircraft. The consumer products line was dropped and The Gill Corporation embraced the science of composites. By the late 1950's, "Gilliner" was synonymous with baggage compartment liners.

During the early 1960's, the corporation developed a line of floor panels to withstand the damage caused by women's spiked heels. Following our entrance into the aircraft replacement floor panel business we earned qualifications to virtually all Boeing, McDonnell Douglas, Airbus, Embraer and Bombardier floor panel specifications. This became our second product line.

In the mid 1980's, floor panel construction changed and balsa was replaced by aramid honeycomb as the core material. That made it necessary for the corporation to develop the capability of making aramid honeycomb and in the early 1990's the corporation secured a contract with Boeing for Nomex® honeycomb. That became our third product line.

In 1991, Stephen Gill became the CEO. Throughout the next two decades, Stephen steered the corporation through an aggressive strategic plan that included acquisitions and organizational enhancements. The company expanded from its original location into a total of 6 buildings and began a series of acquisitions which included: Castle Industries in California, now the Precision Machining department in El Monte, Alcore, Inc. in Maryland, Alcore Brigantine in France and The Gill Corporation - Europe, located in Northern Ireland.

Each division offers unique capabilities which complement the parent corporation. Vertical integration allows the corporation to better manage its quality and production reliability.

In 2009, the third generation Gill family member, Jennifer Gill, joined the corporation at the El Monte campus.

In 2014 the corporation received a contract from Boeing to fabricate, kit and supply all the passenger section floor panels for the Boeing 787 and this opened our fourth product line. In order to accommodate this contract the company purchased a 140,000 square foot building and expanded our El Monte campus to 8 buildings and 400,000 sf. ft. under roof.

In 1945 the corporation began with just M.C. and one employee. After more than 70 years, The Gill Corporation employs over 1,000 people in California, Maryland, France and Northern Ireland.

The company has been successful for over 70 years because of the people and our dedication to our mantra - Make a quality product, deliver it on time, and do whatever it takes to keep the customer happy!
