About Us

Our success is our focus on your safety!

MacPherson & Company has always focused on glass for industry. Since 1969 we’ve supplied Engineered Industrial Safety Windows for:

  • Melt shops (steel & aluminum)
  •  Scrap yards and Ship yards
  • Forge Shops and Foundries

The company history extends back to 1936 to Mr. Kenneth E. MacPherson Senior, the father of Kenneth E. Jr. and Bruce M. MacPherson Senior started All Weld Co, a steel fabrication company, in Cleveland, OH. Both boys grew up working in their father’s company.

On November 1, 1965, MacPherson and Company was founded by the son, Kenneth E. Jr. as an industrial glass company servicing the steel and molten metal industry. Mr. Kenneth Jr. was a business graduate of Western Reserve College of Case Western Reserve University. After college, Mr. Kenneth Jr. worked as a sales representative before starting his own business. Mr. Bruce M. joined his brother Kenneth in 1969. Bruce M. MacPherson graduated from Fenn College, now part of Cleveland State University, with a degree in Metallurgical Engineering and Chemical Engineering and worked in R&D.

Initially MacPherson & Company manufactured the Dual Heat Shield (IRR heat reflecting) windows for molten metal and steelmaking operations. These windows cut the radiant heat energy transfer from over 50% to less than 2%.

MacPherson and Company’s focus shifted to emphasize impact explosion safety for steelworkers after Bruce joined the company. MacPherson and Company started our line of explosion penetration resistant glass (composite type glass) to meet the extreme impact the industrial industry needs to protect operators in the dangerous molten metal areas. Shortly after developing the glass, ten times stronger than the same thickness of “bullet resistant” glass, the need for fabricated custom designed steel sash was formed so that the framework would also be able to withstand the blast from radiant heat vibration, mechanical stress, and explosion on these types of glass windows.

Another common issue in mills was solved by MacPherson and Company with the EASY-RELEASE wedge lock retainers. The issue of long down time waiting for a local glazer to change the glass was replaced with the EASY-RELEASE that allows rapid changes of the windows, including resealing the window within minutes between the heats by in-house maintenance teams verses the waiting for the local glazer. The wedge retainers manufactured today will still work on these early EASY-RELEASE wedge lock brackets. Spare windows allowed regular maintenance to do the change. There is no need for a glass specialist because your regular maintenance people do not touch the glass. Spare windows can be ordered when ordering a new Window Sash System, therefore, after your maintenance team has changed the window, either you or your local glazer can

change the glass. You can also send the spare windows back to us in the custom box crate and we can clean and repair used windows at a much-reduced rate of the new spare window cost.

Through the 70s, 80s and 90s Bruce MacPherson started giving mill consultations with the purchase of new Engineered Window Sash System. Ken and Bruce have traveled the world, supplying specialty windows to steel mills. Hoogoven has been tested from Netherlands to Australia. Today MacPherson and Company continues to give window safety consultations to mills and in recent years also gave existing customers window safety training courses.

In 1997, MacPherson and Company expanded and moved to 95 Pelret Industrial Parkway in Berea, Ohio. This was a custom built, brand new and bigger building. In 2001, Kenneth Jr. retired and sold his portion of MacPherson & Company to MacPherson Engineering Inc. with Bruce and his wife Beverly. Mr. Kenneth, Sr., continued to have an office at Pelret and continued to pass on his knowledge until passing away on November 14, 2013.

Mr. Bruce passed away June 17, 2015. Under Beverly, MacPherson Engineering Inc. became a woman owned business certified by WBENC. Daniel MacPherson was the COO, Jane MacPherson became CTO and with the help of other family members, continued the legacy passed down of supplying custom designed industrial window systems for safety in all heavy industrial applications.

On January 13, 2019, Beverly passed away. The children now sit as board of directors. In 2019, Daniel and Elizabeth retired and leaving Jane nominated as CEO to lead the company for the next generation. Many changes have occurred under Jane. Production changes and R&D has been encouraged. New processes have been developed and the company started working towards ISO 9001 compliance to better serve our customers.

In 2020, Jane moved MacPherson and Company from the 11,000 square foot building in Berea, 60 miles to the Warren, OH 30,000 square foot building, expanding the manufacturing area to over 15,000 square feet! MacPherson Industries building is located in a HUBzone.

For over 55 years, MacPherson & Company products continue to service the industrial communities with a variety of specialty products needed for the safety of the worker. We are proud to acknowledge the contributions of the generations of MacPhersons involved with our business… safety has become a proud family tradition.
