How it started
History
In 1962, the four grandsons of Vicente Vassallo Fiorimonte, an Italian immigrant who established a metal shop in Ponce, Puerto Rico, in 1898, began experimenting with making construction products from a promising new substance, polyvinyl chloride, or PVC. With an initial investment of $3,000, their decision to start manufacturing products with polyvinyl chloride (PVC) lead to the creation of a purely Puerto Rican company that has subsequently been quite successful in the plastics industry.
