Building a Company

SMG has been a leading manufacturer for over 70 years

Since our founding in 1948, Superior Manufacturing Group has committed itself to customer service, quality products and sales support.

Our company was founded in Chicago, Illinois, by Mr. Charles Wood to manufacture and repair rubber entrance mats. The privately held corporation has grown significantly and still maintains its Headquarters in Chicago. The now 10,250 square meter facility also serves as its rubber manufacturing site.


Superior formed its Calhoun, Georgia, U.S.A. facility. This 15,000 square meter location is responsible for the manufacture of the NOTRAX® Dust Control Mats. There is a complete tufting and backing operation. This division is ISO 9001 certified.


Superior opened its vinyl manufacturing facility. In 1992 the facility was moved into a new 14,000 square meter location in Moselle, Mississippi, U.S.A. It is responsible for the manufacture of Notrax® vinyl anti-fatigue matting. This division is ISO 9001 and ISO 14001 certified.


Superior purchased WearProof Mat Co. in Chicago, adding its 70 years of experience to the Notrax® product line. WearProof was a pioneer in the technology of continuous length rubber matting.


Superior became a corporate citizen of Europe by forming Superior Manufacturing Group - Europe B.V. This allows us to support the European matting distribution channel. We are headquartered in Barendrecht, Netherlands, in 6,000 square meter facilities.


Superior purchased the Akro Corporation of Zanesville, Ohio, U.S.A. Akro had been one of Superior's oldest and strongest competitors. The acquisition brought to Superior Akro's 50-plus years of experience, a full product line, patents and trademarks, equipment and expertise.


Superior purchased the Food Service Matting Division of Teknor Apex. This new division will be called Notrax® Food Service Matting Division and has its Customer Service & Sales Center located in Providence, Rhode Island, U.S.A.


Superior has joined the Checkers family on August 17, 2015 by becoming part of the Checkers Industrial Safety Group with headquarters in Broomfield, Colorado with six US manufacturing facilities making a variety of branded safety products including ground protection mats, cable management systems, wheel chocks, safety lights, and warning whips. 


Checkers Safety Group and Justrite Manufacturing LLC. merged on January 30, 2018.  The merger of Justrite and Checkers creates a leading manufacturer of industrial and environmental safety products. Since 1906, Justrite has provided products for the safe management of flammable liquids, and other hazardous materials. Today their products include safety cabinets and large outdoor storage buildings, safety vessels and containers for laboratory and industrial applications, spill containment, safety showers and eye/face wash, and other products that all help industrial customers maintain safe practices. Long recognized as a vital part of environmental, health, and safety programs, Justrite products are available worldwide.

Our commitment is to make quality products and to continue looking for innovative ways of serving our customers.
