Marsh Industries, Inc is a family owned business serving the school construction, school supply, office products, mobile modular, sign shop, and many other markets since 1914. Since this time we have developed and offered a wide variety of visual display board products and have become one of the largest manufactures of such products in the United States. In fact, we are the only manufacturer with a substantial presence in both the school construction market and aftermarket channels such as school supply. At Marsh Industries our products are defined by quality. We never use inferior materials. To keep our prices low, we never outsource to foreign countries as this inevitably leads to low quality products. Instead, we have implemented LEAN techniques and have a dedicated workforce, delivering superior products with competitive pricing. Marsh Industries is a member of the National School Supply and Equipment (NSSEA), Construction Specifications Institute (CSI), Modular Building Institute (MBI), and Certified Educational Facility Planners International (CEFPI). Years of experience and dedication have led us to become the most innovative in the industry, developing revolutionary products such as the Retro-Fit Conversion Board.
