Hot-Rolled Steel - Structural

Semimetais offers a wide range of hot-rolled products and we are a company specializing in the crosswise or longitudinal cutting of these materials.
We were able to cut thicknesses ranging from 1.50mm and widths from 10mm to 1,500mm.
We process and commercialize hot-rolled products with the widest range of thicknesses, formats and characteristics:
