Pegah Trading Group commenced its activities in 1991 (1370 in the Iranian calendar) in the field of selling polycarbonate sheets, crystal sheets, and cartonplast. Over time, with the growing awareness of society about the features and value of these products and the sharp increase in market demand, Pegah Trading Group decided to import these products under the POWER-STRONG brand from Taiwan, Thailand, South Korea, China, and the Netherlands. By 2001 (1380), the company had become one of the leading and largest importers of these products in the country.

In appreciation of supporting domestic producers, Pegah Trading Group also contributed to the local production of these products by updating its activities in the manufacturing of crystal sheets, polycarbonate sheets, and cartonplast, and took firm and significant steps toward progress. Finally, in 2020 (1399), relying on divine grace and the perseverance of its team, the group established a factory covering 12,000 square meters in Abbas Abad Industrial Town, Tehran. By importing advanced machinery from a reputable Italian company, production was launched under the exclusive brand name Pooshesh Polymer Aso Company.
