...For high end of threat levels, we utilize the only certified armor plate manufacturer in the market today, Clifton's High Hard Ballistic Steel. Clifton's is the only actual armor plate on the market today. Competitors of this manufacturer use steel renamed as "wear plate" as their version of armor plate. Wear plate is used to protect dump truck beds and bucket liners in the mining industry.This material is manufactured from start to finish to meet MIL-A-46100D and MIL-A-46177B Armor Plate as per the rigorous U.S. Military's Armor Specifications. It is tested at Aberdeen Proving Grounds to meet the military standards. Once the product conforms to the MIL standards, it must pass additional ballistic testing to meet the Underwriters Laboratory and National Institute of Justice standards. These standards are met through independent tests at certified laboratories.
