STEELS

• Semimetais currently processes and markets products that can be cold-rolled, hot-rolled, galvanized (Zinc-coated), electro-galvanized (Zincor), pickled and oiled, aluminized and prepainted according to the desired characteristics.

ALUMINUM • BRASS • COPPER

• Semimetais processes and markets products such as aluminium, brass and copper in their various characteristics.

SERVICE

• We may say that we are the only locally-owned company specialized in cutting aluminum, copper, brass and steel rolled products. We are able to cut thicknesses from 0.1 to 2.5 mm and widths from 10mm to 1,500mm.

Electro-galvanized Steel

Semimetais offers a wide variety of electro-galvanized products and we are a company specialized in the crosswise or longitudinal cutting of these materials.
We are able to cut thicknesses from 0.1 to 2.5 mm and widths from 10mm to 1,500mm.

We process and commercialize electro-galvanized products with thicknesses of 0.1mm to 10mm and the widest range of characteristics and formats.
