The shomal cement company (public joint stock company) was founded in September 21, 1954 and with the registration number 4492 was registered in the Company Registration Office and Industrial Property of Tehran and was accepted in the Tehran Stock Exchange in March 1968.
The first production line with a capacity of 100 tons per day was operated in 1956 in which wet cement method was applied. In late 1967, the white cement was produced for the first time in the middle east by changing the gray production line to a white production line. The machines applied in this production line are manufactured by G.H.H Company. The second production line with a capacity of 200 tons of gray cement per day was operated in 1971. The wet method was also used for the production of clinker in this line and the machines applied in this line are manufactured by FLS Company.
The third production line with a capacity of 2200 tons per day was operated in 1979 by KHD Company. In 2008, the project of increasing the capacity of the third production line from 2200 tons per day to 4000 tons per day was conducted by Cemag Company. However, due to some design defects the capacity of the line did not reach 4000 tons per day before July 2016. By the grace of God and the efforts of the colleagues, with the change made in the line the production of the third line has reached the nominal capacity (4000 tons per day) since July 2016.
