Construction’s Most Experienced Steel Plate Supplier

Steel plate is a heavily used material in construction due to its high strength relative to weight, as well as its weldability, accessibility and price. More versatile than concrete, steel not only serves as the backbone of infrastructure, but makes up the tools and machines used to erect buildings, bridges and more.

Because there are so many uses for steel plate within the construction industry, Leeco® Steel’s construction customers choose to partner with Leeco because of our ability to supply a wide range of steel plate product in small, medium and large quantities within short timeframes.
