Top Steel Plates Suppliers and Manufacturers in the USA and Canada

Staff Writer

Steel plate or structural steel is simply steel sheet material that can be sliced and welded to develop a more elaborate product. Steel plates are created by compressing several layers of steel together into one and are resistant to rust and abrasion.

Types of steel plates include stainless steel, high carbon, low carbon, alloy, high tensile strength, atmospheric corrosion resistance and clad. Stadiums, skyscrapers, bridges, construction, marine, pressure vessel, military, heavy machinery, earthmover, bulldozer, and offshore equipment are some of the applications of steel plates. In this article, we'll cover details on the top U.S. providers of steel plates, along with our featured list of steel plates on Thomasnet.com.
