Bijar (or Bidjar) Kurdish rugs are often called the Iron Rugs of Iran. The Bijar was a heavy durable rug that has been very popular in the United States. Now the Bijar rug tends to be a finer thinner more Sarouk like rug. Most Bijar Kurdish carpets are woven by Gerrus Kurds in the Bijar area while a finer copy of Bijar carpets are woven by Afshar weavers who live in the Tekab and Tekkenteppe Area in Gerus.

Bidjar rugs and carpets have long had a mystique that makes them a "man's rug". Called the Iron rug of Persia they have an odd feature that few other rugs can match. The densely packed pile is so tight that the pile cannot lay down. Because the fibers are constantly erect when you step on the rug it has a cushioned feel that makes it great to walk upon. For the large segment of the market for whom tactile qualities are important this is a compelling feature even if barely one in one thousand could ever explain why.
