About Us

EST. 1960

In 1960 William J. Graves, using the dining room table as a desk, started Graves Sheet Metal. The company was staffed only by he and his wife. Without the resources to hire union trained employees, William reached out to friends, asking for help in providing the skilled labor he sought. Building a company from nothing, William declared, “If it’s made of metal, We can make it.” To William, this was not just a catchy phrase, it was a guarantee that his customers would receive only the highest quality products, made from the hands of highly skilled sheet metal craftsmen. As the company began to grow, William’s children Mark and Karen began to show interest in the company. The two of them would learn from their parents over the coming years. Some years later, another child of William would join the team, his son William K. Graves or Billy Graves. Mark and Billy would shortly receive their journeyman certification from the Sheet Metal Workers Local Union #20. Still at the helm of Graves Sheet Metal, William J. would reach out to his youngest son, Charles Graves. After several months of discussion with his father, Charles would return to Kokomo, IN to join his father, and elder siblings at Graves Sheet Metal.
