Over 60 Years of steel processing experience

Steel Warehouse Company is the North American leader in high strength steel processing. We developed SWC SHIELD Armor Plate in direct response to our customer's demands for flatter, higher quality armor plate. We produce a complete line of modern armor plate to satisfy both U.S. and Global Standards. Our proprietary alloys and heat treatment capabilities are fully approved by the United Stated Army.

Metallurgical Expertise

: Our Armor processing

SWC SHIELD Armor Plate was developed in close association with the U.S. Army's Aberdeen Proving Grounds. Armor plates are traceable throughout the production process. Our primary Armor products are engineered to satisfy U.S. Military Standards and our in house capabilities provide for the production of unique grades as may be required to satisfy the specific needs of our customer's applications and featured objectives.

SWC Shield

A product line designed and produced to satisfy every U.S. and Global military standard. From the raw steel production through the closely monitored discrete conversion into individual armor plates, SWC SHIELD is the quality and cost effective answer to your armor plate needs. SWC SHIELD is produced in multiple thickness, width and length combinations to minimize scrap and maximize our customer's profitability and ease of manufacturing.
