About

About Arta Leca

We have produced expanded clay aggregate since 1996 on one principle: the number printed on the datasheet is the number that arrives on the truck.

How the company grew

Arta Leca began with a single rotary kiln line in the Mahmoudabad Industrial Zone, Qom. Capacity was expanded in three stages; today three lines supply 450,000 m³ a year across fractions from 0 to 20 mm. Export to the Persian Gulf states, Iraq and Central Asia began in 2013.

How we think about the material

Lightweight aggregate is not a commodity — it is an engineered material with declared parameters. The difference between a good consignment and a poor one shows up in grading spread and bulk-density drift, not in how the granules look. Our technical investment goes into narrowing exactly that spread.

01

Repeatability

Continuous control of kiln temperature and residence time, so the hundredth load matches the first.

02

Traceability

Every consignment ships with a batch number, production date and its own certificate of analysis.

03

Technical support

We work with the design team on grade selection and mix design before the order is placed.
