National Fireproofing Corporation, also known as NATCO, was founded in 1889, in Pittsburgh, Pennsylvania. They re-branded from National fireproofing corporation, to NATCO in 1933. At their peak, they had 23 factories, including one in Haydenville, Ohio.

They are also known for their NATCO conduits. These were telephone tiles, which held underground cables. NATCO conduits were also used as drainage tiles.

In 1933, NATCO changed their official company name from The National Fireproofing Corporation to The NATCO Corporation. Although NATCO manufactured the same products as The National Fireproofing Corporation, there were subtle changes when the company made the transition. The conduits were always called NATCO Conduits, but before the change they said “Manufactured by The National Fireproofing Corporation” after the change it became “Manufactured by The NATCO Corporation”. Since this change occurred in 1933, this information can be used to roughly date NATCO’s products.

    1. They were made by the NATCO corporation, they could have been made at several different plants, but that would depend on where you are located. What do the bricks look like?

  1. Not sure if anyone can help but we have a huge lot (about 2000) pieces of NATCO bricks. There are all kinds from the conduit to the structural most in very good condition in light blue, mint green and a small amount of a light beige. They have never been used. We found these on a lot we were contacted to clear out and would like learn more about them and possibly sell them. I can’t post a photo here but am happy to send photos to anyone

    1. Hi Rebecca,
      We’re looking for beige NATCO brick to repair the back of our home, approximately 200. Hoping your brick might be a match! We are in Pittsburgh, are you local?
      Thank You,

      1. Hi there. We’d be happy to send you a photo to see if the color is right. We are located in South Carolina so we’d have to figure out shipping.
