About Us

Tri-Supply and Equipment



Tri-Supply & Equipment was founded in 1998 to provide a single source for recognized, quality brands of materials, equipment, and service in the construction industry. Tri-Supply & Equipment is dedicated to fulfilling all your material and equipment job site demands. Our extensive knowledge in the construction industry is an invaluable asset extended to our customers with every transaction. With our combined technical expertise, along with wide range of supplies and equipment, we’ll ensure you’ll have what you need, when and where you need it- offering same day service in Delaware, Maryland, Pennsylvania, New Jersey, Virginia, and the metro DC markets.

Founded by Keith Baker, David Curran, and Neal Messick, with over 100 years of combined experience in the industry, Tri-Supply & Equipment is proud to be a independently owned business. Tri-Supply & Equipment emerged as a viable alternative to the Wall Street consolidation atmosphere of the late 1990’s, providing a place of business with familiar faces, great customer service, and unsurpassable knowledge. Today, as in 1998, Tri-Supply & Equipment continues the tradition and mission of providing reliable service of recognizable, quality brands at competitive pricing.

October 2018 marked Tri-Supply & Equipment’s 20th anniversary! Tri-Supply was honored with a Tribute presented by House Representative Valerie Longhurst of the 15th District at our annual holiday open house. The Tribute recognized Tri-Supply’s ownership for their dedication to the industry and the company’s continued commitment to our local communities. Tri-Supply & Equipment is continuously finding new ways for their products to reach the consumer. Most recently, Tri-Supply & Equipment has partnered with Amazon to sell our inventory online within the continental US.


Centrally located in Delaware and the Eastern Shore of Maryland – with everything from nails and hammers to excavators – Tri-Supply & Equipment is dedicated to meeting all your construction material and equipment needs. Over the past twenty years, Tri-Supply & Equipment has steadily become a leading supplier of the excavating, concrete, and masonry contractors, representing only the best manufacturers and suppliers. Our staff is continually relied upon by heavy highway and civil contractors in identifying product specifications and applications.



Over the years Tri-Supply & Equipment continues to have partnerships in our local communities and leading industry organizations. Tri-Supply & Equipment has corporate and sponsorship relationships with the Delaware Humane Association, Muscle Movement Foundation, Delmarva Shorebirds, Wilmington Blue Rocks, Delaware State Colonial BBQ Competition, Beast of the East, and Delmarva Bike Week- just to name a few!

Since our inception, Tri-Supply & Equipment has been a member of several trade groups- the Associated Builders & Contractors (ABC) Delaware chapter, the Delaware Contractors Association (DCA), Land Improvement Contractors (LICA), and Delaware Utility Contractors Association (DUTCA) just to name a few. More recently in 2012, we became members of the National Association of Women in Construction (NAWIC), as our team felt the need to gain involvement from a diversity perspective.

Being engaged in all of these groups has created a culture of involvement at Tri-Supply & Equipment. It has also been rewarding in terms of going from committee members to committee chairs and ultimately board positions at the local and national level. Today, that culture has led from ownership involvement to teammate involvement as our employees are now recognized as community and trade group leaders.
