Estekhraj Co.

Glass Raw Material Exploitation Company

We are the main producer of silica sand for glass and casting industries in IRAN.

In glass industries, silica sand counts for 60-70 percent of raw materials. The quality of glass and crystal wares depend on such factors as particle size distribution and chemical analysis of raw materials especially silica sand. Apart from particle size distribution, the presence of harmful impurities such as Iron oxide directly affects the consistency and quality of the products. Taking into account the unavoidable necessity of the quality of the products this plant was erected in one of the richest mineral regions of Iran abundant with Quartzite in order to beneficiate and produce quality silica sand for foundry men and  glass industries. In our plant, priority is given to the production of standard silica sands for various end-users in either glass or casting industries with an emphasis on high quality and consistency in particle size distribution as well as homogeneity in chemical analysis.
In casting, industries silica sand should meet strict specifications regarding AFS as well as chemical and physical properties which we are dedicated to fulfilling them.
