Allied Metal was established in 1945 by Michael Plotkin as a manufacturer of lighting fixtures. Plotkin changed the focus of the young Allied Metal to the manufacture of pizza smallwares after meeting a challenge from his friend to  develope a baking tray for pizza.

Plotkin quickly began to manufacture items for the developing pizza industry. Such items included pizza serving trays, pizza baking pans and screens, pizza cutters and numerous serving utensils. These products were originally distributed in the New York area where pizza was quick to take hold. As the concept was popularized throughout the U.S., Allied Metal's distribution became national in scope. Plotkin realized that he needed to expand Allied's product line in order to continue to grow and, as a result, he expanded into the manufacture of Asian cookware. Plotkin built the tooling for woks, steamers and lobster pans and sold these items initially throughout New York's Chinatown and ultimately to customers throughout the U.S. Plotkin's daughter, Arlene Saunders, joined the company in 1970 and, upon Plotkin's passing in 1984, inherited Allied Metal.

In 1985, Saunders expanded into the bakery business by manufacturing cake pans, pie pans, cheesecake pans, tart pans, baba cups and many related bakery smallwares.

Allied's bakeware items include removable bottom pans, fluted pans, specialty molds, stainless steel cake rings and pan extenders and numerous baking utensils. Pizza items include serving trays, deep dish anodized and non-stick pans, wood and aluminum peels, proofing pans, dough boxes, cutters and many other pizza utensils. Woks and steamers are also available.
