Youngstown Steel Door Company During World War Two
Youngstown, OH
1924 - 2016

This page updated 8-15-2024.

Youngstown Steel Door was formed in 1924 to manufacture for the railroad industry just what the name of the company implied;  steel doors for boxcars.  Previously, these had been made of wood.  The company had several innovations for rail car doors constructed of steel and also made other steel railcar components.

Youngstown Steel Door Company World War Two Products:  Table 1 shows that the company had $25,084,000 in major contracts during World War Two.  Its first and third contracts were awarded for the manufacture of $3,786,000 worth of trailers for Army Ordnance.   The manufacture of trailers was 15% of the company's major contracts during the war.  The U.S. Navy Department of Aeronautics was the company's largest customer.  Its nine contracts amounted to $20,966,000 in disposable drop tanks for several of its fighters and patrol bombers.  Drop tanks gave Navy aircraft the ability to fly longer distances in the vast expanses of the Pacific Ocean to attack their targets. Using an estimated cost of $150 per unit, Youngstown Steel Door manufactured approximately 140,000 drop tanks.

The loading instructions indicate the amounts of different types of ammunition that can be loaded into the trailer.  Author's photo.

The metal box on the front of the trailer was for the storage of fuzes for the ammunition stored in the main section of the trailer.  Author's photo.

U.S. Navy Drop Tanks:  Youngstown Steel Door Company's main products that helped to win World War Two were drop tanks for U.S. Navy aircraft. 

This 165 gallon drop tank is on display at the National Museum of WWII Aviation in Colorado Springs, CO.  The information below indicates that Youngstown produced these as its part number 44-7280.

This factory photo shows the internal bracing that was required to stiffen the exterior half-shells of a drop tank.  Not only did these braces provide strength, but they prevented the aviation fuel from sloshing back and forth during flight.  The women are operating a spot welder that welded the interior braces to the half-shells.  Aviation fuel weighs six lbs. per gallon.  Each 165 gallon tank added 990 lbs. of take-off weight.  The bracing was needed to keep the exterior half-shells as light as possible without crumpling due to the 990 lbs. of fuel.  Photo courtesy of the Ohio Memory Collection.

The Youngstown Steel Door Company was a busy place during World War Two, providing drop tanks that extended the range of Navy F6F and Marine F4U fighters.  Photo courtesy of the Ohio Memory Collection.

The Youngstown Steel Door Factory:  The factory's address was 3710 Hendricks Road in Youngstown, OH.  The factory, as can be seen in the Google maps satellite photo below, shows that the factory was located between Hendricks Road to the north and Connecticut Avenue to the south.  The east and west boundaries were railroad tracks.

While the Youngstown Steel Door Company went out of business in 2016, parts of it have been repurposed by several other companies that have occupied some of the space.  Below are several images of the factory courtesy of Loopnet.com.

There is a lot of space in this high-bay building. 

This view of the same building shows the high capacity overhead crane in the facility.  

It is rare that a plant layout is available that shows all of the different buildings for a factory complex.
