Padideh Shimi Gharb, a subsidiary of Golrang Industrial Group, was established in 2012 with the aim of producing sulfonation products.
Thanks to the expertise of its management team and the dedicated efforts of its employees, the factory, with an annual production capacity of 16,500 tons, became operational in October 2013. Due to the high quality of its products, the company quickly gained a loyal customer base.

In the second phase of development, new plans were implemented to produce detergent powders with an annual capacity of 50,000 tons, alongside a second sulfonation unit with a capacity of 13,200 tons. Both units are currently operational.

The third phase of Padideh Shimi Gharb’s production development involves the launch of the Zanjan factory, which is dedicated exclusively to sulfonation. Notably, this facility has an impressive annual production capacity of 50,000 tons, entirely allocated to the sulfonation unit and does not include any powder products.
