There are only three factories in this town. The wood industries one in Chali, Pichkooban in Sartappeh and wood saturating factory that has been established in 1932 AD (1311 Iranian date) and because of less use of wood bars in rail way its production has been limited. Of course a kind of this factory has been made in Ghazvin province that only isolated the wood. So that was the first saturating factory in Iran.
