Guardian has been an original equipment manufacturer (OEM) and original design manufacturer (ODM) of garage door components and operators for over 30 years. Guardian’s reputation is synonymous with quality and enjoys the privilege of supplying products to market leading OEMs and dealers in over 30 countries, spanning 6 continents.
As residential construction and the market for sectional garage doors grew in the 1980s, Guardian founder and owner, Herbert Liu, was asked by garage door OEMs and hardware suppliers to help meet the increased demands for operators and door hardware. Operations for die castings, steel stampings and assembly were established to serve a partnership with DNS in Florida and provide operators for Clopay. Guardian and DNS later acquired the design rights of the garage door operator, producing it in Malaysia and Taiwan.
While hardware and operator supply expanded through an exclusive distributor in the USA, Guardian focused on the Australian and European garage door operator and hardware markets. Guardian became and remains the leading supplier to door OEMs in Australia and New Zealand with its residential rolling door openers, sectional garage door openers and rolling and section door hardware offerings. Pride is taken in being an exclusive component supplier to the largest European garage door manufacturer as well as the long-term relationships that have been built with large and small companies throughout the world.
In 2011, Guardian USA was established to directly serve North American garage door manufacturers, regional garage door distributors, and door dealers. The headquarters was opened in Santa Fe Springs, California along with an office and warehouse in Medley, Florida. In 2013, a Midwest office and warehouse was opened in the Chicago area.
In 2018 Guardian moved its US headquarters to El Segundo, CA. With a distribution center in Ontario, CA; regional sales and distribution centers in the Midwest and on the East Coast, Guardian has committed to a sustainable growth plan in the USA and aims to further extend our services to our customers by providing local design capability, shortening lead time and providing a one-stop-shop for our customers.
