Alloy and Carbon Plate Specialists

Delaware Valley Steel


A Nationwide Steel Supplier

Located just outside Philadelphia, PA, Delaware Valley Steel has been the Northeast’s and Mid-Atlantic’s premier steel plate supplier and processor for over 60 years. We specialize in thick plates (up to 14″ thick), especially for the power generation and machining industries.

What sets us apart is our oxy-fuel cutting expertise. Four fully CNC-controlled burning machines give you unparalleled quality and give us the flexibility to meet your demanding delivery needs. At Delaware Valley Steel, we carry a full complement of steel plate processing equipment to help us provide services including burning, plate-saw cutting, heat-treating, blanchard grinding, and country-wide shipping.

In addition, we are constantly expanding our inventory of carbon, PVQ, and alloy steel plates, A36 steel road plates, and have recently started offering ABS Grade A plates, which means our steel can be used in the structural architecture of ships, barges, and marine equipment. Let us be your thick steel plate supplier. Check out our array of products, including A515 Grade 70 and 4140 plate, and please inquire about additional sizes and grades not listed.
