AGI – Augusto Guimarães & Irmão

Operating in the Portuguese market since 1915, we are a company steeped in tradition but focused on the future.

Over the years we have kept up with technological developments, which has allowed us to maintain our current position with diversified offers and to gain the trust of our partners, making us leaders in the supply of plastic raw materials and equipment for the plastics industry.

In order to meet the latest market demands, we have extended our area of operation to the construction sector, offering a wide range of modern, creative and functional solutions for professionals.

We are a family company operating on the Portuguese market with the commitment and dedication of various people and we constantly strive to exceed all expectations in highly competitive markets.

In 2002, the Guzman Group acquired 50% share in AGI, allowing us to extend our area of operation in the distribution of raw materials to the entire Iberian Peninsula. In turn, through the acquisition of ROMGOM S.L.U. (Spain), now called AGI Spain, AGI is continuing the process of internationalisation of its services and products in the Equipment for the Plastics Industry Department and the Construction Materials Department.


The company was pioneer in having quality certification, in Portugal, according to ISO 9001.

Currently, we have ISO 9001:2015 certification.
