We were founded in 2003 around one unglamorous specialization: grinding Egyptian limestone into calcium carbonate, precisely and repeatably. We never diversified away from it. Twenty-three years later, it is still the only thing we do.
Quality starts with the stone, not the machinery. Our limestone is what puts CaCO₃ purity at 99.9% and brightness at 97%, and holds iron oxide and silica to 0.001% each. Grinding controls fineness — but no amount of processing adds brightness the rock never had.
That stone is processed across two plants. 10th of Ramadan handles the fine grades, from 5 to 15 microns; El-Saff handles coarser material, from 20 to 45. Both work under the same ISO 9001:2015 certified system — and two sites mean your supply never rests on a single location.
What customers actually buy, though, is consistency. Any grinder can hit a specification once; holding it batch after batch, for years, is the harder problem. Every batch is verified by laser-diffraction particle size analysis and brightness testing before release — so the spec you approve is the spec that arrives.
