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.

Cold-Rolled Steel

Cold rolling of steel occurs with the metal below its recrystallization temperature (usually, at ambient temperature), which increases its strength through work-hardening of over 20%. It also improves the surface finish and maintains tighter tolerances. Semimetais offers a wide variety of cold rolled products. 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 cold rolled products with thicknesses of 0.1mm to 10mm and the widest range of characteristics and formats.
