Military Steel Plate from Clifton Steel
You are here:


For more than five decades, Clifton Steel has served as an integral supplier of aluminum and steel armor plate to U.S. Government facilities, vehicle manufacturers, fabricators, machine shops as well as commercial vehicle and facility protection systems. This experience provides us with the knowledge, and expertise to understand our customer’s requirements and deliver, without compromise. Our continued re-investment into our business and addition of processing capabilities allow us to provide preprocessed components for our customers who prefer to get semi-finished or finished parts ready for use. For our customers who process in-house, Clifton Steel can provide stock size plates as well as cut parts when preprocessing becomes a bottleneck in the production process.


Unlike most suppliers in this business, military armored plate has been, and continues to be, a core product to Clifton Steel. Our in-house heat treat lines are specifically designed to supply light gauge armor plates to Mil DTL 46100 Rev E, Mil DTL 12560 Rev J, and Mil DTL 46177 Rev C table ready for processing.

The rigid controls of our heat treat process allows us to produce some of the flattest plates in the industry, without the need for flattening. Mechanical flattening of heat treated plates can produce uneven stresses in the product which, when cutting, will cause the plate to warp with potential costly damage to the processing equipment. The stock maintained is always available to the latest revision of the specification, however, we continue to stock the previous revision in support of existing vehicle programs that require this material. Our DFAR compliant armor plate is a prerequisite in supplying material to Federal Agencies. Products for commercial applications can be tested to comply with UL or NIJ specifications.
